These units are very efficient at low static pres sures. All fan blades are certified under NAFM test code ratings. MUCKLE VENTS come as a complete Cackaged unit, ready to install and can e installed equally well on old buildings or incorporated into new structures. They are designed for use on industrial, commercial and institutional buildings. These units are available in 15 sizes varying from 254 cfm to 10280 cfm with some sizes turning at slow speed for quieter operation. These ventilators are powered with a standard make, continuous duty, full ball bearing, completely enclosed electric motor of the permanent split capacitor type so that 2 and 4 speed switches can be used. Explosion proof motors are available. The base and throat of MUCKLE VENTS are made from 14 and 16 gage steel. The storm bands and cones are made from 18 and 20 gage steel. The parts are hot dipped galvanized after fabrication to insure complete coverage of all sheared edges and welded seams and joints. The motors are directly connected to the propeller--no belts to wear out, tighten or replace. MUCKLE VENTS are designed completely weather proof--rain can not enter the flue past the storm band. Automatic or motor driven back draft dampers are available with or without fuseable fire links. Corro sion resistant coatings can be supplied on order.
