Heat Controller MARS-08049 Blower Motor Mounting Adapter Kit

Product Description

The HEAT CONTROLLER MARS-08049 is a Torsion-Flex mounting adapter kit designed for 9-inch and 10-inch blower motors. The kit provides a vibration-isolating mount solution for 29 and 39 frame motors as well as 5-inch motors commonly found in residential and light commercial HVAC systems. The hardware bundle includes 3 grommets, 1 bolt, 1 nut, and 2 steel washers, giving the technician everything needed for a complete mounting installation. HVAC service professionals install this kit when replacing or repositioning blower motors that require torsion-flex-style isolation mounting to reduce noise and vibration transfer into the air handler cabinet.

This adapter kit is suited for HVAC blower motor installations involving 29-frame and 39-frame motors, as well as 5-inch motors. It is appropriate for residential and light commercial air handler and furnace blower applications where torsion-flex mounting is specified by the equipment design. The included grommets provide the flexible isolation interface between the motor and the mounting bracket, which is critical for reducing operational vibration and noise in ducted forced-air systems.

Compatibility

Designed for use with 9-inch and 10-inch blower motors on 29-frame and 39-frame motors, as well as 5-inch motors in torsion-flex mounting applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Disconnect electrical power to the air handler or furnace at the breaker and verify power is off before removing or repositioning the blower motor. Ensure grommets are fully seated in the mounting bracket before securing the bolt and washers to avoid uneven load distribution. Follow equipment manufacturer guidelines and applicable local mechanical codes when securing blower motor assemblies.
