Mcdaniel Metals Ace 2020-6 Tall Filter Base 4 Inch

Product Description

The MCDANIEL METALS ACE 2020-6 is a tall filter base designed to house 4-inch air filters in residential HVAC systems. It installs at the base of a furnace or air handler to create a dedicated filter section, replacing field-fabricated filter boxes or undersized factory filter slots. The cabinet measures 21-3/8 inches wide by 5-3/4 inches deep by 22 inches tall and accepts 20 x 20 inch filters in 1-inch, 2-inch, or 4-inch depths. Full internal insulation limits condensation and heat loss at the filter section. A hinged access door and perimeter gaskets keep the installation clean and airtight. HVAC technicians and installers use this unit to standardize filter access on forced-air systems sized up to 5 tons.

This filter base is suited for residential forced-air furnace installations where the existing unit lacks an adequate filter section or where a field upgrade to a deeper filter is required. It accommodates standard 20 x 20 inch filter stock, making filter replacement straightforward for both service technicians and building occupants. The hinged door eliminates the need for tools during routine filter changes, reducing callbacks and simplifying maintenance on occupied-building service accounts.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Shut down and lock out the furnace or air handler at the disconnect before beginning any ductwork or cabinet modifications. Secure the filter base to the unit using sheet metal screws and seal all seams with foil-faced tape or mastic per local mechanical code requirements. Verify door swing clearance before finalizing placement to ensure unobstructed filter access.
