Slant Wall Fans
Properly sized ventilation options are crucial to the success of your greenhouse. We inventory full line slant wall fans, the ultimate in green-house ventilation. Six-bladed propellers with quiet operation at low RPM and aluminum dampers. Standard sizes range from 18” to 60” with additional options available.
Steel Box Fans
Steel box fans installed in the gable of the greenhouse provide an excellent first stage of ventilation. The box fan is an economical alterna-tive to our slant wall fan and features 3/4 HP direct drive motor with an aluminum exhaust shutter.
Evaporative Cooling Pad
Available in 5’ increments, this system comes complete with pump, float valve and all required plumbing. Our stainless steel trough has enough water capacity to function without a sump tank, thus producing a user-friendly, self-contained system.
EZ Roll-Up Curtain System
Our EZ Roll-Up package includes everything needed for natural greenhouse ventilation. In addition, you can choose a manual crank or automatic system. Our heavy duty, 13 mil. coated 10 x 12 weave fabric (not 6 mil. poly) is strong enough to withstand harsh conditions.
Z-Lock Drop Down Curtain
Our Economy Curtain System is a more economical way to passively ventilate your high tunnel or coldframe. Growers prefer curtains that roll up from the middle as opposed to rolling up from the bottom; crank rotations are cut by half because our crank rod rolls from the middle. Our crank handle makes this sytem easy to operate. For even smoother operation, the crank package can be upgraded to include a 13:1 gear reduction box. Poly film can also be upgraded to strong 12 mil. curtain fabric. The Economy Curtain can be adapted to straight or curved side walls. System comes complete with crank handle, crank rod, curtain guides and all hardware necessary to install.
