Mcdaniel Metals DP-18X44-22GW Welded Corner Drain Pan

Product Description

The MCDANIEL METALS DP-18X44-22GW is a galvanized steel drain pan designed to collect condensate beneath air handlers and furnaces with coils. Constructed from 22-gauge galvanized steel, it measures 18 inches long by 44 inches wide by 2 inches deep, providing a large secondary containment footprint for residential and light commercial HVAC equipment. The welded corners eliminate seams that can leak over time, and the single 3/4-inch drain connection allows for direct tie-in to a condensate drain line. At 10.27 pounds, it is sturdy enough for long-term service without being unwieldy to position during installation.

This drain pan is intended for use under air handlers or furnaces equipped with evaporator coils in split-system or package configurations. The 18-inch by 44-inch footprint accommodates larger coil cabinets common in mid- to high-capacity residential systems. It is typically installed in attic, closet, or utility-room applications where secondary condensate containment is required by local mechanical code. HVAC technicians and installers use this pan as both a primary and overflow drain pan depending on equipment layout.

Key Features

• Welded corners provide leak-resistant construction without seam sealant
• 22-gauge galvanized steel resists corrosion in humid condensate environments
• Single 3/4-inch drain connection for standard condensate line tie-in
• Large 18 x 44 x 2 inch profile fits wide coil cabinet footprints
• Gray finish galvanized construction meets typical mechanical code requirements for secondary drain pans
• Manufactured in the USA

Compatibility

Designed for use with air handlers or furnaces equipped with evaporator coils. Verify equipment base dimensions against the 18 x 44 x 2 inch pan footprint before installation.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Shut off power to the air handler or furnace at the disconnect and at the breaker before positioning the pan. Ensure the drain connection is routed to an approved condensate disposal point per local mechanical code. Do not install beneath equipment with a base footprint that overhangs the pan edges, as this will compromise containment.
