All Aluminum Shutter. The LRW Shutter is an all aluminum damper featuring an extruded aluminum frame with interlocking aluminum blades for maximum weather seal. Double panel shutters (LRW45 and larger) are constructed with a rigid ‘T’ section center member to prevent shutter blades from sticking. The LRW Shutter has nylon bearings on all movable linkage. A sturdy, extruded aluminum tiebar is connected exactly on the blade centers.

CALL FOR PRICING

American Coolair’s AL all-aluminum fans are the answer to concerns about rust and corrosion in today’s damp greenhouse environment. Combined with an aluminum wall housing an aluminum shutter, and a vinyl coated wire guard, the AL fan will provide years of trouble-free and corrosion-free service.

AL fans feature all-welded angle frame construction for a rugged and durable unit. The fan panel has a deep spun orifice for maximum efficiency.

AL fans utilize Coolair’s exclusive drive assembly used on our fans for over 80 years. The die-formed aluminum blades are bolted to a cast aluminum hub, which also serves as the fan pulley. Power is applied through V-belts directly to the propeller with the blade load concentrated directly over the fan earrings, thus elimination overhung bearing load.

LEAD TIME IS 3-4 WEEKS. FREIGHT IS NOT INCLUDED DEPENDING ON DESTINATION
