Airflow solutions for Agricultural equipment manufacturers
Poultry ventilation systems
Poultry ventilation equipment must support different needs as a flock grows. Minimum ventilation helps manage moisture and air quality while limiting heat loss during brooding. Transitional and tunnel ventilation provide greater air exchange and cooling as bird size and heat loads increase.
For OEMs developing poultry exhaust and tunnel ventilation fans, these requirements shape impeller selection, motor specifications, and installed performance. Revcor engineers airflow components around the fan assembly and its intended operating range, helping manufacturers validate performance before production.
Common OEM Challenges
How Revcor Helps
Deliver tunnel ventilation airflow against installed resistance
During hot-weather operation, tunnel fans must deliver the airflow specified for the poultry house’s ventilation strategy. Shutters, guards, housings, and discharge cones affect installed fan output, while cooling pads and house inlets contribute to the pressure the equipment must overcome.
Validate the fan at poultry-house design pressures
Revcor evaluates impeller performance with the fan’s surrounding components and the OEM’s specified pressure range in mind. Testing helps establish whether the proposed configuration delivers the required airflow under representative resistance, supporting the OEM’s fan ratings and equipment selection.
Support minimum ventilation during brooding
Young birds require ventilation that removes moisture and stale air while limiting unnecessary heat loss. Whether the equipment uses timed operation, variable speed, or dedicated minimum-ventilation fans, OEMs need to understand the airflow delivered at the intended settings.
Establish delivered airflow at brooding settings
Revcor evaluates the fan at the operating settings specified for brooding, with representative housing and shutter restrictions and the required house pressure. Testing establishes delivered airflow and motor requirements at those settings, giving the OEM a basis for selecting its minimum-ventilation configuration. House-level timing and air distribution remain part of the ventilation system design.
Maintain useful performance as ventilation stages increase
As birds grow and conditions change, ventilation systems bring additional fans online or increase fan speed. Changing house pressure can affect each fan’s output, so a single rated airflow point does not describe performance throughout transitional and tunnel operation.
Map fan output across transitional and tunnel duties
Revcor evaluates how airflow and motor demand change across the pressure and speed range specified for transitional and tunnel operation. We use those results to refine impeller configuration and establish performance data for the OEM’s staging strategy, including duties where additional fans operate or higher output is required.
Manage power demand during extended tunnel operation
Hot-weather ventilation can require multiple fans to run for long periods. Small differences in the power needed to deliver the required airflow can become significant across a house, particularly when higher resistance shifts the fan away from its preferred operating point.
Evaluate power input at the required airflow and pressure
We assess blade geometry, diameter, pitch, and motor requirements against the OEM’s duty points. Configuration decisions consider airflow and power together, helping manufacturers assess efficiency at the pressures their poultry ventilation equipment is designed to serve.
Account for poultry-house exposure and cleaning
Poultry-house fans can encounter litter dust, feathers, humidity, and ammonia-bearing air. Cleaning between flocks may introduce additional moisture or chemical exposure. These conditions influence material, finish, and construction requirements at the fan’s location.
Specify construction for flock operation and between-flock cleaning
Revcor works with the OEM to define the dust, feather, humidity, and ammonia-bearing air exposure at the fan’s location, along with the cleaning conditions expected between flocks. Those requirements inform impeller materials, coatings, and construction within the agreed scope. Production specifications carry those decisions forward alongside the validated airflow and structural requirements.
Swine and Livestock ventilation systems
Swine barn ventilation equipment must support changing airflow demands as animals grow and seasonal conditions shift. Tunnel ventilation and positive-pressure crossflow designs place different demands on fan configuration, with equipment moving air along the barn or supplying air across it. Larger-diameter fans must deliver the required volume against the resistance of the intended installation while managing power input and mechanical loads.
Revcor works with equipment manufacturers to configure or develop impellers and assemblies for these applications. We evaluate blade geometry, housing and venturi interactions, motor requirements, and structural integrity against defined equipment targets, supporting the OEM’s broader barn ventilation design.
Common OEM Challenges
How Revcor Helps
Deliver required airflow through the barn
Tunnel exhaust fans and positive-pressure crossflow supply fans operate within different inlet and discharge arrangements. Housings, guards, shutters, and other restrictions affect delivered airflow. Free-air performance alone does not establish whether a fan will meet the equipment’s requirements at the specified barn operating pressure.
Configure for tunnel exhaust or crossflow supply duty
Revcor establishes the fan’s intended role, airflow target, and pressure range with the OEM. We evaluate the impeller’s interaction with the housing, venturi, and relevant inlet or discharge restrictions, then validate the specified configuration under representative conditions. Results support the OEM’s fan selection and barn ventilation calculations.
Maintain predictable low-output barn ventilation
During low-demand operation, ventilation must support moisture and air-quality management without unnecessary air exchange and heat loss. OEMs need reliable airflow data at reduced settings, particularly when their equipment must operate against the specified barn pressure.
Validate low-output performance in the intended exhaust assembly
Revcor evaluates the selected pit or wall-exhaust configuration at the OEM’s minimum-ventilation settings, accounting for its housing, shutters, and specified pressure range. Results establish the airflow and motor requirements equipment designers need when setting low-demand operation.
Withstand manure-related moisture and corrosive exposure
Fans serving livestock buildings may encounter humidity, dust, ammonia, and other manure gases. Exposure varies with fan location, particularly between pit exhaust and general barn exhaust, affecting material, coating, and construction requirements.
Match construction to pit or barn-exhaust exposure
Revcor establishes whether the impeller will serve pit exhaust or general barn exhaust and defines the relevant moisture, manure-gas, and cleaning exposure with the OEM. Material, coating, and construction decisions follow the conditions at that location. Where a product family includes both exhaust arrangements, each configuration’s production specifications reflect its defined exposure and structural requirements.
Manage power and structural demands in larger-diameter fans
Larger-diameter fans must deliver the required airflow within the equipment’s power and mechanical limits. Blade geometry, pitch, speed, and housing clearance affect efficiency and motor loading. Extended operation also makes structural integrity and resonance important considerations during development.
Optimize impeller geometry and motor requirements
Revcor evaluates diameter, blade geometry, pitch, and speed against the airflow and pressure targets within the available housing. We establish motor requirements and validate structural performance through the agreed scope, which may include stress analysis, resonance evaluation, and endurance testing. Proven platforms are configured first, with new geometry developed when existing options cannot meet requirements.
Maintain performance across fan sizes and barn applications
OEM product lines may span multiple fan diameters, capacities, and configurations for tunnel ventilation and positive-pressure crossflow barns. Changes in housing, shutters, motor, or speed can alter airflow and power requirements. Performance established for one model cannot automatically represent the entire lineup.
Validate each model against its assigned ventilation duty
Revcor works with the OEM to establish the airflow range, pressure requirements, and assembly constraints for each pit or wall-exhaust model. We identify where a proven impeller platform can support related configurations and evaluate each specified combination at its required operating points. The resulting production specifications reflect the performance and motor requirements of each model.
Greenhouse ventilation systems
Greenhouse equipment must support both air exchange with the outdoors and circulation within the growing space. Exhaust fans move air through screens, shutters, and other restrictions, while circulation fans help distribute air around crops and growing structures. Each function requires a different approach to airflow, pressure, and fan configuration.
Revcor works with greenhouse equipment manufacturers to engineer impellers and assemblies around these requirements. We evaluate the fan’s intended airflow path, operating range, and environmental exposure to help OEMs deliver equipment suited to changing growing conditions.
Common OEM Challenges
How Revcor Helps
Maintain exhaust airflow through screens and inlet restrictions
Insect screens, louvers, shutters, and evaporative cooling pads can add resistance to greenhouse ventilation systems. Fans must deliver the specified air exchange against that resistance, rather than rely on an unrestricted airflow rating.
Validate exhaust performance against the specified resistance
Revcor evaluates airflow, pressure, and motor requirements across the resistance range defined by the OEM. We assess the impeller within representative fan geometry and restrictions, helping manufacturers select a configuration that meets the exhaust target under the intended system conditions.
Provide useful circulation around crops and growing structures
Circulation fans must support air movement beyond the immediate fan outlet. Benches, hanging baskets, crop spacing, and plant growth influence the circulation pattern the equipment needs to support. High airflow volume alone does not establish whether a fan meets the OEM’s air-delivery objective.
Configure the fan for its crop-area circulation objective
Revcor works with the OEM to define the fan-level air-delivery requirements for circulation around benches, hanging baskets, or other growing arrangements. We evaluate blade geometry, diameter, pitch, and surrounding components against those requirements. Fan-level validation supports the equipment design, while the OEM verifies fan placement and circulation coverage within the intended greenhouse layout.
Balance routine air exchange with peak solar-load demand
Greenhouse ventilation demand changes with sunlight, outdoor conditions, humidity, and crop requirements. Equipment designed only around peak exhaust output may not provide the airflow or power performance needed during lower-demand operation.
Characterize performance across the ventilation settings
Revcor evaluates airflow, pressure, speed, and power input at the operating points specified for the OEM’s control strategy. We use those results to align impeller configuration and motor requirements with both routine air exchange and higher-output ventilation.
Limit power demand during extended circulation
Greenhouse circulation fans may operate for long periods to support air mixing around the crop. Across multiple fans, the power required to deliver that circulation becomes an important equipment-design consideration. Guards, blade configuration, and motor matching all influence performance.
Evaluate power at sustained-circulation settings
Revcor evaluates airflow and power input together at the settings specified for sustained greenhouse circulation. Representative guards and mounting restrictions are included when assessing blade configuration, speed, and motor requirements. This helps the OEM select a configuration that delivers the required circulation output within its power target during extended operation.
Account for humidity and growing-environment exposure
Depending on their location, greenhouse fans may encounter condensation, irrigation mist, fertilizer exposure, or cleaning agents. These conditions affect material and finish requirements, particularly for equipment operating close to growing areas.
Specify construction for the fan’s growing-area location
Revcor works with the OEM to distinguish the exposure of an exhaust fan from that of a circulation fan near irrigation mist or crop-treatment activity. The defined condensation, fertilizer, and cleaning conditions inform impeller materials, finishes, and assembly requirements within the agreed scope. Those decisions become part of the production specifications for the intended fan location.
Dairy ventilation systems
Dairy cooling equipment must support air movement where cows rest, feed, and gather. Fans serving freestalls, feed lanes, and holding areas face different requirements for air delivery, mounting, and coverage. Equipment must also withstand moisture, bedding dust, manure-related exposure, and extended hot-weather operation.
Revcor works with dairy ventilation equipment manufacturers to configure or develop impellers and assemblies around these demands. We evaluate fan geometry, installed restrictions, motor requirements, and structural integrity against defined equipment targets, supporting the OEM’s broader cooling and ventilation design.
Common OEM Challenges
How Revcor Helps
Turn fan output into useful airflow at cow level
A high airflow rating alone does not establish how effectively a fan supports cooling where cows stand or lie down. Impeller geometry, discharge direction, guards, and mounting arrangements influence the air delivered from the equipment and the OEM’s ability to achieve its intended coverage.
Configure the fan around its air-delivery objective
Revcor works with OEM engineers to define fan-level airflow requirements for the intended application. We evaluate blade geometry, diameter, pitch, and surrounding components against those targets, while the OEM verifies cow-level airspeed, fan placement, and coverage in the barn layout.
Serve freestalls, feed lanes, and holding areas with different equipment configurations
Long rows of stalls, feeding areas, and crowded holding spaces present different cooling objectives and installation limits. A fan configuration suited to one area may not deliver the required performance within another area’s available diameter, mounting position, or clearance.
Configure for the intended barn location
Revcor works with the OEM to establish the fan-level airflow target and installation constraints for the freestall, feed-lane, or holding-area model being developed. Available diameter, mounting interfaces, clearances, and discharge requirements guide the impeller or assembly configuration. We validate each specified configuration against its equipment targets, while the OEM verifies placement and coverage in the intended barn area.
Preserve airflow through protective guards and mounting structures
Dairy circulation fans must accommodate protective guards, supports, and other nearby components. Those features can obstruct the inlet or discharge, change the airflow pattern, and increase the power needed to deliver the specified output.
Evaluate performance in the guarded fan assembly
Revcor evaluates how the impeller interacts with the intended guards, housing, and supporting geometry. Testing helps identify installed losses and informs blade configuration and motor requirements before the equipment design moves into production.
Manage power and mechanical demands during extended cooling operation
Hot-weather cooling can require multiple fans to run for long periods. Large-diameter impellers and sustained operating speeds place demands on motor loading, balance, and structural integrity, making both power input and mechanical performance important to equipment development.
Align airflow, motor requirements, and structural performance
We evaluate airflow, speed, and power input at the specified duty points, alongside impeller construction, balance, and structural requirements. The agreed validation scope addresses the demands of extended operation and establishes specifications for repeatable production.
Withstand moisture and debris near animal cooling areas
Depending on placement, dairy fans may encounter sprinkler drift, washdown moisture, bedding dust, and manure-related exposure. These conditions vary between barn locations and influence material, coating, and assembly requirements.
Match construction to the cooling area’s exposure
Revcor defines the expected exposure with the OEM for the fan’s intended location, including sprinkler drift near cooling areas, washdown moisture, bedding dust, and manure-related contaminants where applicable. Impeller materials, finishes, and assembly requirements are selected around those conditions. The production design carries those requirements alongside the airflow and structural targets for the specified dairy fan configuration.
