How This AMFCO Aluminum Air Filter Is Constructed
The AMFCO 7-1/2″×24″×5/16″ Exact Aluminum Foil Mesh Air Filter is meticulously engineered for strength, durability, and effective filtration. Each component is selected and assembled to ensure a long-lasting, high-performance product capable of withstanding repeated cleaning cycles and demanding operational environments.
Durable Aluminum Frame
The filter’s robust frame is constructed from .030″ thick aluminum, providing a rigid and corrosion-resistant enclosure for the media pack. The frame features mitered corners, precisely cut and joined for enhanced structural integrity, and is securely fastened with pop-rivet(s). To facilitate drainage during cleaning, the frame is equipped with drain holes in three corners, ensuring efficient water removal and preventing residue buildup.
Multi-Layered Aluminum Screen Wire Media
At the core of the filter’s performance is its media pack, composed of multiple layers of corrugated aluminum screen wire. These layers are assembled in a criss-cross fashion, creating a dense yet permeable matrix that effectively captures airborne particulate through impingement. This design maximizes the surface area for particle collection while maintaining a low resistance to airflow, crucial for system efficiency. The aluminum construction ensures the media is washable, reusable, and resistant to degradation from moisture or common contaminants.
Protective 24 Gauge Aluminum Face Grids
The media pack is firmly enclosed between two layers of 24 gauge aluminum expanded metal face grids. These grids serve a dual purpose: they protect the delicate corrugated media from damage during handling, installation, and operation, and they contribute significantly to the overall strength and rigidity of the filter. The expanded metal design allows for maximum airflow while securely holding the media in place, ensuring the filter maintains its structural integrity even under varying air pressures.
Installation Instructions for AMFCO Aluminum Air Filters
Proper installation of your AMFCO 7-1/2″×24″×5/16″ Exact Aluminum Foil Mesh Air Filter is essential for maximizing its performance and ensuring the longevity of your HVAC system. Follow these guidelines carefully to achieve optimal filtration and airflow.
Before Installing
- Verify Dimensions: Double-check that the filter’s actual dimensions (7.5″×24.0″×0.3125″) match the filter slot or housing requirements.
- Inspect Filter: Ensure the filter is clean and free from any shipping damage.
- Identify Airflow Direction: Locate the airflow direction arrow on your existing filter or system housing. The new filter should be installed with the arrow pointing in the direction of the airflow.
- Safety First: Turn off the HVAC system or appliance before attempting to remove or install filters. Wear appropriate personal protective equipment if necessary.
Installation Steps
- Locate Filter Slot: Identify the filter access panel or slot in your furnace, air handler, or return air grille.
- Remove Old Filter: Carefully slide out the old filter. Note its orientation and the direction of the airflow arrow.
- Clean Housing (Optional): If the filter housing is dirty, gently wipe it clean to ensure a good seal for the new filter.
- Orient New Filter: Position the AMFCO filter so that the airflow arrow printed on its frame points in the direction of the air moving through your system (typically towards the furnace/air handler).
- Slide Into Place: Gently slide the new filter into the designated slot. Ensure it sits flush and securely within the housing, without bending or forcing.
- Secure Access Panel: Close and secure the filter access panel or grille.
- Restore Power: Turn the HVAC system or appliance back on.
Notes by System Type
- Upflow Furnaces: Airflow typically moves upwards. Install the filter with the arrow pointing up towards the furnace.
- Downflow Furnaces: Airflow typically moves downwards. Install the filter with the arrow pointing down.
- Horizontal Furnaces/Air Handlers: Airflow moves horizontally. Ensure the arrow points in the direction of the air handler.
- Return-Air Grille Installations: The filter is often installed directly behind a return air grille. Ensure the arrow points towards the ductwork leading to the air handler.
Cleaning and Maintenance for AMFCO Washable Aluminum Air Filters
The AMFCO 7-1/2″×24″×5/16″ Exact Aluminum Foil Mesh Air Filter is designed for repeated washing, offering significant cost savings and environmental benefits. Regular cleaning is crucial to maintain optimal airflow, filtration efficiency, and the longevity of your HVAC system. Follow these steps for effective maintenance.
Washing Procedure
- Remove Filter: Turn off your HVAC system. Carefully remove the dirty filter from its housing.
- Pre-Rinse: Using a garden hose or utility sink, rinse the filter with warm water to remove loose debris. Spray against the direction of normal airflow to dislodge particles from the media.
- Apply Cleaner: For stubborn grease or heavy particulate, apply a mild detergent or a specialized filter cleaning solution. Allow it to soak for 5-10 minutes, following the cleaner’s instructions.
- Brush Gently: Use a soft brush (e.g., a dish brush) to gently scrub the filter media and frame, paying attention to heavily soiled areas.
- Thorough Rinse: Rinse the filter thoroughly with warm water until all soap residue and dislodged contaminants are gone. Ensure water drains freely from the frame’s drain holes.
- Shake & Dry: Gently shake the filter to remove excess water. Allow it to air dry completely in a well-ventilated area before reinstallation. Do not use heat to dry.
- Reinstall: Once completely dry, reinstall the filter into your HVAC system, ensuring the airflow arrow points in the correct direction.
What NOT To Do
- Do NOT use harsh chemicals: Avoid strong acids, alkalis, or abrasive cleaners that can damage the aluminum.
- Do NOT use high-pressure washers: High pressure can deform the delicate aluminum screen wire media.
- Do NOT bend or force the frame: This can compromise the filter’s structural integrity and fit.
- Do NOT reinstall wet: A wet filter can promote mold growth and restrict airflow.
- Do NOT use heat to dry: Excessive heat can warp the aluminum frame or media.
Cleaning Frequency Guide
- Residential Use: Typically every 1-3 months, depending on household activity, pets, and local air quality.
- Commercial Use: Every 2-4 weeks, or as indicated by system monitoring, due to higher occupancy and operational hours.
- Industrial Use (Grease/Mist): Weekly or bi-weekly, especially in applications like range hoods or coolant mist collection, where buildup is rapid.
- High Dust Environments: More frequent cleaning (e.g., monthly) may be required in dusty areas or during construction.
