What Are Poultry Exhaust Fans?

Due to the enclosed nature of poultry houses, unwanted gases will likely build up if you don't replace the air quality correctly and frequently. This can change the air composition and cause significant harm to you, your poultry, and your livelihood. Exhaust fans keep the levels of carbon dioxide, ammonia, and other gases at a safe level.

Types of Poultry Exhaust Fans

Wall-Mounted Poultry Exhaust Fans

Wall-mounted options are typically mounted in the sidewalls of the building with a wind hood and louvre shutter to stop back draught.

Ceiling-Mounted Poultry Exhaust Fans

Ceiling fans mounted in GRP chimneys are an excellent option for propelling exhausted air high into the external air stream

Tunnel Ventilation Fans

Explicitly designed for poultry houses, when specified correctly this option is a great way of moving large amounts of air over the birds to cause a cooling effect. An ideal air speed of 2 metres per second is required, with the air not taking more than 60 seconds to transfer through the building. Any longer than this and the air begins to warm up again. An equal amount of air inlet area is required to allow free movement of air.

Direct Drive Poultry Exhaust Fans

Direct drive exhaust fans offer a fantastic option to adjust the fan's speed for different situations and seasons.

Belt-Drive Poultry Exhaust Fans

A generally cheaper alternative to direct drives, the belt-drive exhaust fan operates as an on / off fan.
