Eliminate hot and cold spots in your greenhouses, factories or any controlled environment with tube fans. The DURAFAN duct/pit fan comes in an 8" or 10" size and totally enclosed sealed ball bearings. Stainless steel tube fans come in diameters from 12"-36".

After fans are mounted, attach duct pipe or polyethylene ventilation tubing to distribute air throughout your space. We have 50 lb. PVC duct pipe and ventilation tubing in varying diameters. Attach it to the ceiling with stainless steel tube clamps and poly tube hangers. Get the air to all parts of your buildings with PVC tees, 90- and 45-degree elbows, end caps, couplers and tapered reducers.
