What Is the 20x20x2.625 Galvanized Steel Universal Holding Frame?
The AMFCO 20×20×2.625 Galvanized Steel Universal Holding Frame is a foundational component for advanced air filtration systems, designed to securely house standard filter media pads. This robust frame ensures that air passes through the intended filtration media, rather than bypassing it, which is critical for maintaining indoor air quality and protecting sensitive HVAC equipment.
By providing a stable and sealed enclosure, this holding frame optimizes the performance of various filter media types, including polyester and fiberglass pads. The integrated foam or rubber gasket plays a crucial role in preventing air leakage around the filter media, thereby enhancing the overall efficiency of particle capture and ensuring compliance with air quality standards where applicable.
Unlike disposable filter frames, this durable galvanized steel unit is a permanent fixture, allowing for the replacement of only the filter media. This approach not only reduces waste but also offers greater flexibility in selecting media tailored to specific filtration requirements, from basic dust arrestance to finer particle removal, supporting systems that aim to meet or exceed ASHRAE standards for air filtration.

How This Frame Is Constructed
The AMFCO 20×20×2.625 Galvanized Steel Universal Holding Frame is meticulously engineered for strength, longevity, and optimal filtration performance. Each component is selected and assembled to ensure a secure and efficient housing for your chosen filter media.
Galvanized Steel Frame
The primary structure of this holding frame is crafted from high-quality galvanized steel. This material is chosen for its exceptional durability and superior resistance to corrosion, rust, and environmental wear, making it ideal for demanding HVAC applications. The all-welded construction ensures structural integrity, preventing warping or deformation over time and providing a consistently secure enclosure for the filter media. This robust design contributes significantly to the frame’s long service life and reliability.
Integrated Gasket
A critical feature of this universal holding frame is its integrated gasket, made from either foam or rubber. This gasket is strategically placed to create a tight seal between the filter media and the frame, as well as between the frame and the HVAC system’s housing. Its primary function is to prevent bypass air — air that would otherwise flow around the filter media instead of through it. By eliminating bypass, the gasket ensures that the filtration system operates at its maximum intended efficiency, capturing more contaminants and protecting downstream components more effectively.
Installation Instructions
Proper installation of your AMFCO Galvanized Steel Universal Holding Frame is essential to ensure maximum filtration efficiency and system performance. Follow these guidelines for a secure and effective setup.
Before Installing
- Safety First: Always wear appropriate personal protective equipment, including gloves and eye protection, when handling HVAC components.
- Inspect Components: Verify that the holding frame and filter media are free from damage. Ensure the gasket is intact and properly seated.
- Check Dimensions: Confirm that the actual dimensions of the holding frame (20” × 20” × 2.625”) match the opening in your HVAC unit and are compatible with your chosen filter media.
- Gather Tools: Have any necessary tools ready, such as screwdrivers or fasteners for securing the frame (if applicable, clips and fasteners are sold separately).
Installation Steps
- Prepare Opening: Ensure the filter housing or duct opening is clean and free of debris.
- Orient Frame: Position the holding frame correctly within the HVAC unit’s filter slot or housing. Ensure the gasket side faces the direction that will create a seal against the system or the next component.
- Insert Filter Media: Carefully slide the chosen filter media pad (polyester, fiberglass, etc.) into the holding frame. Ensure it sits flush and securely within the frame’s interior.
- Secure Media (if applicable): If your system or frame design requires additional securing, use appropriate filter holding clips or fasteners (sold separately) to firmly hold the media in place within the frame.
- Seal System: Once the frame with media is in place, ensure it forms a tight seal with the surrounding HVAC unit. The integrated gasket should compress slightly to prevent any air bypass.
- Test System: After installation, run the HVAC system briefly to check for proper airflow and listen for any unusual noises or signs of air leakage.
Notes by System Type
- Upflow Systems: Install the frame and media so that the air flows upwards through the filter.
- Downflow Systems: Install the frame and media so that the air flows downwards through the filter.
- Horizontal Systems: Ensure the frame is securely seated to prevent sagging of the filter media, especially in larger units.
- Grille/Return-Air Installations: For frames installed directly behind return air grilles, ensure easy access for future media replacement and cleaning.
Cleaning and Maintenance
The AMFCO Galvanized Steel Universal Holding Frame is designed for long-term use and requires minimal maintenance. While the filter media pads will need regular replacement, the frame itself can be cleaned to ensure continued optimal performance and durability.
Washing Procedure for the Frame
- Remove Filter Media: Before cleaning, carefully remove the used filter media pad from the holding frame and dispose of it according to local regulations.
- Rinse Thoroughly: Using a hose or faucet, rinse the galvanized steel frame with warm water to remove accumulated dust, dirt, and debris. A mild detergent can be used for stubborn grime.
- Gentle Scrub (if needed): For heavily soiled frames, a soft brush or cloth can be used to gently scrub the surfaces. Avoid abrasive cleaners or harsh scouring pads that could damage the galvanized coating.
- Inspect Gasket: Check the integrated foam or rubber gasket for any signs of wear, tears, or degradation. Ensure it is still pliable and capable of forming a tight seal.
- Dry Completely: Allow the frame to air dry thoroughly before reinstallation. Ensure no moisture remains, especially in crevices, to prevent potential corrosion or mold growth.
What NOT To Do
- Do NOT use harsh chemicals or solvents that could damage the galvanized coating or the gasket material.
- Do NOT bend or forcefully reshape the frame, as this can compromise its structural integrity and fit.
- Do NOT obstruct airflow by installing a damaged or improperly cleaned frame.
- Do NOT install the frame while it is still wet, as this can introduce moisture into the HVAC system.
- Do NOT attempt to clean the filter media pad unless it is specifically designed as a washable media. This frame is for holding disposable or washable pads.
Cleaning Frequency Guide for the Frame
The cleaning frequency for the galvanized steel holding frame depends largely on the operating environment and the type of filter media used. The frame typically requires less frequent cleaning than media replacement.
- Residential Environments: Inspect and clean the frame every 6–12 months, or during major media changes.
- Commercial Environments: Inspect and clean the frame every 3–6 months, especially in high-traffic or dusty areas.
- Industrial Environments: Inspect and clean the frame every 1–3 months, depending on the particulate load and operational demands.
