Ventilation & Fans

Greenhouse exhaust fans and ventilation equipment sized for real houses. We carry shutter exhaust fans in common sizes — from small circulation fans to large belt-drive units — plus intake shutters, thermostats, and controllers.

Good ventilation is non-negotiable: it drops summer temperatures, controls humidity, and keeps air moving through the canopy. Size your fans to the house — a 30x100 foot greenhouse needs far more airflow than an 18x50. Not sure what you need? Call Henry at (630) 408-2201 and we will size it with you.

Pair fans with cooling water walls for evaporative cooling in hot climates, and find shutters, louvers, and mounting parts in hardware and accessories. Factory-direct pricing. Large fans ship by freight or on our dedicated truck.
