TJERNLUND VSUB20SS Datasheet

for providing combustion air or sidewall or vertically venting heating appliances, dryers and ovens. Suitable for use on con- densing equipment. Can be installed indoors or outdoors. Use with the CPC-3 Constant Pressure Controller, Closed Loop VFD and TD-Series Pressure Transducer for an Automatic-Variable Speed system which will modulate to always deliver the perfect amount of draft or combustion air. For an Adjustable-Fixed Speed system, use an Open Loop VFD to manually adjust speed of the VSUB. Housing Construction: Constructed of 14-gauge, Type 316L stainless steel with con- tinuous welds. The blower outlet rotates 180° for installation flexibility. The motor chassis slides away from the housing on polyethylene guides for easy motor and impeller access. Impeller: Backward inclined, Type 304 stainless steel, Class 1 impeller is both dynamically and statically balanced with permanently attached balancing weights. Motor: Three phase, 3 HP, 208-230/460 VAC, TEFC, EPACT High Efficiency Rated, arctic-duty, thermal overload protected, per- manently lubricated and sealed ball bearing.
