Seal-tite 92RFB-142220 Return Air Box 14.75x22.19x20 in

Product Description

The SEAL-TITE 92RFB-142220 is a return air box designed for ducted HVAC systems where a dedicated return air plenum is required at the air handler or furnace. Measuring 14-3/4 inches wide by 22-3/16 inches tall by 20 inches deep, this box provides the structural enclosure that channels return air from the conditioned space back to the equipment. HVAC installers and sheet metal mechanics use return air boxes like this one to complete the return-side ductwork in residential and light commercial forced-air systems, ensuring proper airflow balance and a sealed transition at the unit cabinet.

This return air box is suited for residential and light commercial forced-air heating and cooling installations. It is typically installed at the base or side of a gas furnace, air handler, or fan coil unit where a field-fabricated or factory-matched return air plenum is needed. The 14-3/4 by 22-3/16 by 20 inch form factor fits applications where those opening dimensions align with the equipment cabinet and the surrounding framing or platform.

Key Features

• Dedicated return air enclosure sized at 14-3/4 inches x 22-3/16 inches x 20 inches
• Designed to seal the return air path and reduce air leakage at the unit connection
• Structured box form supports integration with standard return duct systems
• SEAL-TITE construction intent focused on minimizing infiltration at the return plenum

Compatibility

Designed as an OEM-style return air box for forced-air HVAC systems where a 14-3/4 inch by 22-3/16 inch by 20 inch return opening is required at the air handler or furnace cabinet.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal mechanic. Shut down and lock out the HVAC system before beginning work on the return air plenum. Secure all connections and seal seams with appropriate duct sealant or mastic to meet local mechanical code requirements. Verify that the box dimensions align with both the equipment cabinet opening and the structural platform or framing before fastening.
