Congress top quality single groove die cast pulleys. For use with 4L (1) type V belts. Each pulley is individually boxed and clearly marked. The bore and belt groove of each pulley is machined and balanced for concentricity assuring smooth op- eration and long service life of both pulleys and belts. Each has socket set screw (installed). Pulleys 5” and smaller are solid type; 6” and larger are spoke type. 1/2” bore pulleys have no keyway. 5/8”, 3/4” and 1” bore have standard keyway.
Permits speed variations of approximately 30%. Ideal for air conditioning units and other installations where speeds must be changed or it is impossible to pre-determine the correct speed. Suitable for use with 3L(0), 4L(A), and 5L(B) V-belts. Quality die cast construction and individually machined for long, smooth service life. Furnished with socket set screws.

HEAT RECLAIM CEILING FANS
Substantially reduces heating costs in commercial and industrial buildings by eliminating heat stratification that occurs near the roof. Warm air trapped at the ceiling often measures 10 to 25° more than at floor level. A practical solution is the installation of heat fans to recirculate the hot air down to floor level at a low ve- locity. Floor-to-ceiling air temperatures become uniform and cold spots are eliminated.
Heat fans will effectively de-stratify a 2500 sq. ft. area at a maxi- mum 30 ft. ceiling height, or 1200 sq. ft. at ceiling heights of 35 to 40 ft. If close control of fan speeds is required, a solid state variable speed control is available for remote mounting. Motor is permanently lubricated PSC type; operates on 115V AC power and draws only 1 amp. UL listed.
