This blower is used to inflate two layers of polyethylene greenhouse covering. Heat savings of up to 40% have been realized from this system. This blower has automatic-reset thermal protection which shuts off the motor should excessive temperatures develop. An adjustable air inlet damper is included.

Used for tacking down poly film with Bostitch tacker. This heavy gauge will last many years.

Designed to be used with the above adjustable blower. Made of heavy weight alum­inum, complete with bolts, nuts, washers, and complete installation instructions.

The use of outside air inflation helps reduce condensation between double layer poly­ethylene. System includes blower, exhaust air deflector, mounting bracket, 72” inlet air hose, air inlet with locking ring and bug screen. The four port air deflector reduces film deterioration by directing air away from the poly layer. White cap reduces degradation and eliminates air flow restrictions. The inlet hose may be cut any desired installation length. 115 volt, Hz, 1/125 hp, 60 CFM.

Used to measure air pressure inside the pillow formed by inflated 2-layer poly cover on a greenhouse. This meter measures from .05 to +3.0” of water. Pillow pressure should be adjusted to .2” for hot days to .45” on cold and windy days. Mount on vertical support and connect tubing between gauge and polyfilm. Includes 8’ double column plastic tubing, connector fittings, mounting screws, red oil indicator, and level for leveling unit.
