EZ-2020-FCS Filter Coil Support 20x20 Fan Coil Filter Base 22 Gauge Galvanized Steel

The EZ-2020-FCS is a professional-grade E-Z Filter Base and coil support, functioning as the structural foundation for your HVAC system's indoor air handler or fan coil unit. As a genuine M&M Manufacturing OEM-spec component, it is designed to manage the critical transition between the return air duct and the evaporator coil, acting as the system's primary protection for airflow integrity. Engineered for high-efficiency electric air handlers and upflow furnace series, the EZ-2020-FCS ensures your evaporator coils remain clean by providing a 100% airtight housing for standard 20x20 filtration. By utilizing this heavy-duty support base, you prevent the cabinet sagging and air bypass common with field-fabricated filter racks, maintaining factory-certified static pressure and cooling performance.

Key Features

• Genuine Part Number EZ-2020-FCS: Guaranteed factory-direct fit for standard 20" x 20" fan coil footprints, eliminating the need for complex field-built transitions.
• Universal Filter Acceptance: Specifically engineered to house 1", 2", or 4" thick filters without the need for additional spacers or door modifications.
• Eliminate Air Bypass and Noise: Replaces flimsy, taped-on filter frames with a rigid 22-gauge steel cabinet that prevents whistling and air leakage.
• Advanced Airflow Monitoring: Features a no-door lift access design that allows for instant filter inspections and lightning-fast replacements without removing furnace panels.
• Heavy-Duty Structural Support: Built to carry the weight of full-size evaporator coils and air handlers, providing a level, vibration-resistant mounting surface.

🛠️ HVAC Depot Pro Tip

Take a Picture First — Before setting your fan coil or furnace onto the EZ-2020-FCS base, photograph the internal guide rails and the filter access opening. Since this base is designed to hold the weight of the entire unit, ensuring it is perfectly level is the most critical step; use high-density isolation pads under the corners if your floor is uneven to prevent mechanical vibration from traveling through the ductwork. Always perform a dry fit with your chosen 4-inch filter before final duct connections to confirm you have enough clearance for the lift-access door to move freely.
