What Is the 20x20x2.625 Stainless Steel Universal Air Filter Holding Frame?
The 20x20x2.625 Stainless Steel Universal Holding Frame is a durable, reusable component manufactured by American Metal Filter Company (AMFCO) designed to securely house various types and depths of air filter media pads within commercial and industrial HVAC systems. Unlike disposable filters, this frame provides a permanent structure into which filter media — such as polyester or fiberglass — can be inserted and replaced. Its primary function is to create a rigid, sealed enclosure for the filter media, ensuring that all air passes through the filtration material and not around it.
This holding frame is critical for maintaining filtration efficiency by preventing air bypass, a common issue with ill-fitting or poorly sealed filters. The integrated foam or rubber gasket plays a vital role in creating an airtight seal between the frame and the filter bank, maximizing the effectiveness of the chosen filter media. By providing a stable and secure foundation for filtration, it contributes significantly to improved indoor air quality and the protection of HVAC equipment from particulate matter.
Key Benefits of the AMFCO Universal Holding Frame

How This Holding Frame Is Constructed
The AMFCO 20x20x2.625 Stainless Steel Universal Holding Frame with Gasket is meticulously engineered for strength, longevity, and optimal filtration performance. Each component is selected and assembled to ensure a reliable and efficient solution for securing air filter media.
Frame Material: Stainless Steel
The entire frame is constructed from high-grade stainless steel. This material is chosen for its exceptional resistance to corrosion, rust, and chemical degradation, making it ideal for use in humid, industrial, or otherwise challenging environments. Stainless steel also offers superior structural integrity, ensuring the frame maintains its precise dimensions and rigidity over years of service, even under varying air pressures and temperatures.
Frame Construction: All-Welded Design
The frame features an all-welded construction, which is a critical aspect of its durability and performance. Unlike frames with riveted or crimped joints, an all-welded design eliminates potential weak points and gaps, providing a seamless and robust structure. This construction method enhances the frame’s rigidity, prevents flexing, and ensures that the frame maintains its shape, which is essential for a tight seal and preventing air bypass.
Integrated Gasket: Foam or Rubber
A key feature of this universal holding frame is the integrated foam or rubber gasket. This gasket is strategically placed to create a tight, impenetrable seal between the holding frame and the filter bank or housing. Its primary function is to prevent unfiltered air from bypassing the filter media, thereby maximizing the efficiency of the filtration system. The gasket material is resilient, ensuring it maintains its sealing properties even after repeated use and exposure to environmental factors.
Universal Design for Media Pads
The frame’s universal design allows it to securely hold various depths of standard filter media pads, such as polyester or fiberglass. This adaptability provides flexibility for users to select the appropriate media based on their specific filtration requirements, without needing to change the entire frame. The design ensures that once the media is in place and secured (with clips/fasteners, sold separately), it remains firmly positioned within the airflow path.
Installation Instructions
Proper installation of your AMFCO 20x20x2.625 Stainless Steel Universal Holding Frame with Gasket is essential to ensure maximum filtration efficiency and system performance. Follow these guidelines for a secure and effective setup.
Before Installing
- Safety First: Always turn off the HVAC system’s power at the thermostat and circuit breaker before beginning any installation or maintenance.
- Inspect Frame: Verify that the holding frame is free from damage and that the gasket is intact and properly seated.
- Confirm Size: Double-check that the actual dimensions of the holding frame (20×20×2.625 inches) match the requirements of your filter bank or housing.
- Gather Tools: Have any necessary tools ready, such as screwdrivers for access panels or clips/fasteners (sold separately) for securing the frame.
Installation Steps
- Power Down: Ensure the HVAC system is completely powered off to prevent accidental startup during installation.
- Access Filter Bank: Open the access panel or door to the filter section of your air handling unit or ductwork.
- Remove Old Components: Carefully remove any existing filters or frames from the slot.
- Position Holding Frame: Insert the AMFCO stainless steel holding frame into the designated filter slot. Ensure the gasket side faces the direction that will create a seal against the filter bank’s frame. The frame should fit snugly.
- Secure Frame: If your system requires it, use appropriate clips, fasteners, or mounting hardware (sold separately) to firmly secure the holding frame in place. This prevents movement and maintains the seal.
- Insert Filter Media: Once the frame is secure, insert your chosen filter media pad (polyester, fiberglass, etc.) into the holding frame. Ensure the media is fully seated and covers the entire opening.
- Close Access Panel: Close and secure the access panel or door to the filter section.
- Restore Power: Turn the HVAC system’s power back on at the circuit breaker and thermostat.
Notes by System Type
- Universal Fit: This holding frame is designed for universal application and can be installed in upflow, downflow, or horizontal airflow configurations. The key is always to ensure a tight, gasketed seal against the filter bank.
- Gasket Orientation: Always ensure the gasket makes full contact with the mating surface of the filter bank to prevent air bypass, regardless of the system’s orientation.
- Multiple Frames: For larger filter banks requiring multiple frames, ensure each frame is securely installed and sealed to its adjacent frames or the system housing.
Cleaning and Maintenance
The AMFCO 20x20x2.625 Stainless Steel Universal Holding Frame with Gasket is designed for long-term use and requires minimal maintenance. While the filter media pads will need regular replacement, the stainless steel frame itself can be cleaned to ensure its integrity and continued performance.
Washing Procedure for the Frame
- Power Off System: Always turn off your HVAC system at the main power source before attempting any maintenance.
- Remove Frame: Carefully remove the holding frame from the filter bank.
- Remove Media: Dispose of the used filter media pad according to local regulations.
- Rinse Frame: Rinse the stainless steel frame thoroughly with warm water to remove loose dust and debris.
- Clean with Mild Detergent: If necessary, use a soft brush or cloth with a mild, non-abrasive detergent to clean any stubborn grime from the stainless steel surfaces. Pay attention to the gasket area to ensure it is clean.
- Rinse Thoroughly: Rinse the frame again with clean water to remove all detergent residue.
- Air Dry Completely: Allow the frame to air dry completely before reinstallation. Ensure no moisture remains, especially around the gasket.
- Reinstall: Once dry, insert a new filter media pad into the frame and reinstall the frame into your HVAC system following the installation instructions.
What NOT To Do
- Do NOT use abrasive cleaners, scouring pads, or steel wool on the stainless steel, as these can scratch the surface and compromise its corrosion resistance.
- Do NOT use harsh chemical solvents, strong acids, or bleach, which can damage the stainless steel finish or the gasket material.
- Do NOT bend or distort the frame during cleaning or handling, as this can compromise its fit and sealing capabilities.
- Do NOT reinstall the frame while it is still wet, as this can promote mold or mildew growth within the HVAC system.
Cleaning Frequency Guide for the Frame
- Light Commercial Environments: Inspect and clean the frame every 6–12 months, or as needed.
- Standard Commercial Environments: Inspect and clean the frame every 3–6 months, especially if the filter media is changed frequently.
- Industrial or High-Dust Environments: Inspect and clean the frame every 1–3 months, or more frequently depending on the particulate load and system demands.
