Aciq 70G36H Knockdown Supply Plenum with Top

Product Description

The ACIQ 70G36H is a knockdown supply plenum with top, designed for field-trimmed installation on residential and light commercial HVAC systems. Fully assembled, the plenum measures 13.5 inches wide by 20.5 inches deep by 30 inches high and is sized for use with 14-inch wide furnaces. The knockdown construction collapses flat for easy transport to the job site, reducing handling time and cargo space. Trim to final height using standard tin snips to match the supply opening of the air handler, furnace, or evaporator coil. The unit ships with four trimmable side panels and one trimmable top panel, allowing precise on-site fitting without specialized tools.

This plenum is suited for residential forced-air heating and cooling applications where a field-fabricated or replacement supply plenum is needed above a furnace or air handler. The trim-to-fit design makes it compatible with multiple equipment brands and configurations. It is commonly installed during new construction, equipment changeout, or ductwork retrofit projects. The A-width designation fits 14-inch wide furnace cabinets, a standard size found across many residential gas and electric furnace product lines.
