The INTERNATIONAL COMFORT PRODUCTS A33 is a replacement V-belt measuring 35.2 inches in outside circumference, manufactured to Browning A-section specifications. This belt transfers rotational power between the motor sheave and blower pulley inside forced-air HVAC equipment, including air handlers, furnaces, and package units. It is a direct-drive-adjacent component suited for installations where belt-driven blower assemblies are used. HVAC technicians and mechanical contractors install this part during routine preventive maintenance or as an emergency replacement when a worn or snapped belt causes blower failure.
The A33 belt is commonly used in residential and light-commercial forced-air systems with belt-driven blower assemblies. It fits standard A-section sheave and pulley configurations found across a wide range of air handler and furnace platforms. This belt is appropriate for any application requiring an A-section belt at the 35.2-inch outside circumference specification.
Designed as an OEM-style replacement A-section V-belt for belt-driven blower assemblies in residential and light-commercial forced-air HVAC equipment requiring a 35.2-inch outside circumference belt.
Belt replacement is performed by licensed HVAC technicians. Disconnect and lock out all electrical power to the unit before accessing the blower compartment. Relieve tension on the motor mount adjustment before removing the old belt, and re-tension the new belt to the manufacturer-specified deflection range after installation. Inspect sheaves and pulleys for wear or misalignment before installing the new belt to avoid premature failure.
