McDaniel Metals 21X23X36 Plenum R8 M21X23X36R8

The McDaniel Metals M21X23X36R8 is a 21 by 23 by 36 inch plenum with R-8 insulation, for furnace and air handler connections.

The specific 21 by 23 inch cross section reflects the reality that equipment outlets are not standardised across manufacturers. Furnace and air handler cabinets vary in width and depth, and their supply outlets vary correspondingly, so plenums are produced in a range of sizes to match particular equipment rather than to a small set of round numbers.

Selecting a plenum that fits the equipment outlet directly avoids the field fabricated transition that would otherwise be required. Field transitions are a recurring source of problems: they are frequently made too abruptly, which creates turbulence and static pressure at the highest velocity point in the system, and they add joints in a location where leakage is proportionally most costly.

R-8 insulation satisfies the more stringent energy code requirements for duct in unconditioned space, keeps the plenum exterior above dew point in cooling operation so condensation does not form, and absorbs blower noise at the point of generation.

Confirm the equipment outlet dimensions before ordering, seal the equipment connection and all plenum seams with mastic or approved tape, and support the plenum so its weight is not carried by the equipment cabinet.

Applications include residential and light commercial furnaces, air handlers, and fan coils.
