Description:
The VSUB12SS Variable Speed Universal Blower is suitable
for providing combustion air or sidewall or vertically venting
heating appliances, dryers and ovens. Suitable for use on condensing 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 continuous 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, 1 HP, 208-230/460 VAC, TEFC, EPACT High
Efficiency Rated, arctic-duty, thermal overload protected, permanently lubricated and sealed ball bearing.
