Mars M41112 Double Inlet Blower Wheel Clockwise

Product Description

The MARS M41112 is a double inlet blower wheel designed for use in forced-air HVAC systems where clockwise rotation is required. This wheel draws air through both inlet sides simultaneously, increasing airflow volume without increasing the overall unit footprint. It is a direct-drive or belt-drive compatible component installed inside air handlers, furnaces, and fan coil units. HVAC technicians and sheet metal mechanics are the primary trades responsible for selection and installation. The part number CSA50202 is referenced in supplier documentation as an associated designation for this wheel.

This blower wheel is suited for residential and light commercial forced-air applications. It is commonly found in air handler cabinets and furnace blower assemblies where a double-width, double-inlet (DWDI) configuration is specified. When replacing a failed or damaged blower wheel, matching the rotation direction, bore size, and blade diameter to the original equipment specifications is essential for proper airflow performance.

Key Features

• Double inlet design pulls air from both sides for increased airflow capacity
• Clockwise (CW) rotation as viewed from the drive side
• Referenced under supplier designation CSA50202
• Intended for use in air handlers, furnaces, and fan coil blower assemblies
• DWDI configuration suits residential and light commercial forced-air systems

Compatibility

Designed as an OEM-style replacement blower wheel for residential and light commercial HVAC air handlers and furnace blower assemblies requiring a double inlet, clockwise-rotation wheel.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all electrical power to the unit before removing the blower assembly. Verify bore diameter, wheel diameter, wheel width, and rotation direction before installing the replacement wheel. Ensure the set screw is properly secured to the motor shaft before returning the system to service.
