Greenhouse fan FAQ
How many fans does a greenhouse need?
It depends on volume and local summer heat. Enter your dimensions in the Fan Selector to see the recommended quantity.
How are fans placed with pad-cooling?
Fans go on one end wall and cooling pads on the opposite end so cool air flows the full length.
Why a louvered model?
Louvers close when the fan stops, reducing heat loss in cold weather and backflow in wind.
Farm fan FAQ
How many fans does a poultry house need?
It depends on volume, animal count and local summer heat. Enter your dimensions in the Fan Selector or send them via WhatsApp for a project calculation.
Where should barn fans be mounted?
Wall fans go on the end wall to pull air along the barn; hanging fans go above feeding and resting areas, angled slightly towards the animals.
220V or 380V?
With three-phase power, 380V models suit long, heavy operation. Without it, the 140×140 220V single-phase model connects to standard mains.
Exhaust fan FAQ
Are exhaust fans used in winter too?
Yes — run intermittently to remove humidity, dust, smoke and odours; louvers close when stopped to limit cold air.
Are they suitable for fire smoke extraction?
No. They are for general extraction of process smoke, dust and odours. Fire smoke extraction requires certified (e.g. F400) fans.
Can they be mounted on sandwich panels?
Yes, with the installation kit for sandwich-panel and sheet walls.
