Green-Tek is poised to be North America’s premium Greenhouse Environmental Supplier. Our HAF Fan Series gives you great performance, energy efficiency and an air pattern that is designed for heat de-stratification.
The OSHA approved guard means the fan can be mounted at any height. Our totally enclosed air over motor can be used in the harshest greenhouse environments. The Green-Tek series HAF fans are easy to install and will give years of trouble free service. The ideal spacing is every 50’ but call one of our ventilation design engineers for proper sizing of your HAF fan or a recommendation of a Green-Tek complete Greenhouse environmental system.
