Raypak MVB 503, Installation & Operating Instructions Manual

Page: 213 / 213

Description:
VSUB-Series Variable Speed Universal Blowers are suitable
for providing combustion air or sidewall or vertically venting
non-condensing heating appliances, dryers and ovens. 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, high temperature coated, Class 1 impeller
is both dynamically and statically balanced with permanently
attached balancing weights.
Motor:
Three phase, 2 HP, 208-230/460 VAC, TEFC, EPACT High
Efficiency Rated, arctic-duty, thermal overload protected, per-
manently lubricated and sealed ball bearing.
