TJERNLUND VSUB16R User manual

Description:
The VSUBR Series Variable Speed Universal Blowers (with
Ryton® coated impellers) are 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 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.

Backward inclined, Ryton® PPS coated for superior corrosion
resistance, Class 1 impeller is both dynamically and statically
balanced with permanently attached balancing weights.
