Product Description
The MCDANIEL METALS MCDA-ACE2025-6N is a filter base designed for electric air handling units. It provides a secure, insulated housing for standard 20×25 inch filters and serves as the intake filtration point in the air handler assembly. The unit accommodates 1 inch, 2 inch, or 4 inch depth filters in the 20×25 inch face size, giving installers flexibility to match filtration requirements to the application. The filter access door is located on the narrow side of the base for easier serviceability in tight mechanical spaces. HVAC technicians and sheet metal installers handle this component during new construction and replacement installs.
This filter base is suited for residential and light commercial electric air handling unit installations. It is typically installed at the return air inlet of the air handler, upstream of the heating and cooling coil. The narrow-side door orientation is well suited for installations where front access is limited. The fully insulated construction helps reduce condensation and thermal loss at the filter section, which is especially relevant in humid climates or unconditioned mechanical rooms.

Installation Notes
Installation is typically performed by a licensed HVAC technician or sheet metal installer. Disconnect and lock out electrical power to the air handler before beginning work. Verify the filter base orientation and door-swing direction before final fastening to ensure unobstructed filter access after installation. Follow local mechanical codes for sealing and insulation continuity at the filter section.
