About exhaust fans for pig houses
Exhaust fans create the slight negative pressure that pulls fresh air in through the inlets. A fan’s real airflow depends on the static pressure of your house, not on the size of its blades, so fans are chosen from performance data together with inlets, the air-tightness of the house and the controller.
Common configurations
Axial exhaust fans
Wall or chimney fans.
Housings and drives
Belt or direct drive, different housings.
Shutters
Close when the fan stops.
Selection checklist
Before we send a layout or quotation, we confirm these points with you.
| Point to confirm | Why we ask |
|---|---|
| Airflow at static pressure | From test data at your working pressure. |
| Power use and noise | Running cost and comfort. |
| Housing corrosion protection | For ammonia and washing. |
| Mounting and guards | Safe installation. |
| Speed control | Variable or stepped. |
| Emergency ventilation | What happens in a power cut. |
Dimensions, materials and quantities are confirmed for each project.
Scope of supply
| Usually in the package | Agreed in each contract |
|---|---|
| Fans, air inlets, cooling pads and heaters | Air-tightness of the building |
| Climate controller and sensors | Heat source and power supply |
| Air filtration units where ordered | Standby power and alarm call-out |

Frequently asked questions
How many fans does my house need?
We calculate the airflow for your hottest weather from the house size, pig weight and climate, then choose fans by their airflow at your working pressure.
