How This AMFCO HI Series Aluminum Filter Is Constructed
The AMFCO HI Series Aluminum Screen Mesh Air Filter is meticulously engineered for exceptional durability and effective filtration. Each component is carefully selected and assembled to ensure a long service life and consistent performance in demanding residential, commercial, and industrial applications.
Robust Aluminum Frame
The filter’s frame is constructed from .030” thick aluminum, providing exceptional rigidity, lightweight handling, and superior corrosion resistance. The frame features precisely mitered corners, which are cut and joined for enhanced structural integrity and a clean finish. These corners are securely fastened with durable pop-rivet(s) to prevent separation. Thoughtfully included drain holes in three corners facilitate efficient water drainage during the cleaning process, preventing water retention and promoting faster, more complete drying.
Multi-Layer Aluminum Screen Media
At the core of the filter’s performance is its media pack, composed of multiple layers of high-quality aluminum screen wire. These layers are corrugated and assembled in a criss-cross fashion, creating a dense yet low-resistance matrix. This unique configuration maximizes the impingement surface area, allowing the filter to effectively capture large airborne particulate, grease, and coolant mist while maintaining optimal airflow through the HVAC system.
Protective Face Grids
Encasing and supporting the aluminum screen media are durable 24 gauge aluminum face grids. These grids provide essential structural support and protection to the delicate media pack, preventing damage from impact, excessive airflow velocities, or handling during maintenance. Their robust construction ensures the filter maintains its structural integrity throughout its operational life and during repeated cleaning cycles, contributing to the filter’s overall longevity and reliability.
Installation Instructions for AMFCO Aluminum Screen Mesh Air Filters
Proper installation of your AMFCO HI Series 9×33-1/2×3/16 Exact Aluminum Screen Mesh Air Filter is essential for optimal performance, system efficiency, and filter longevity. Follow these guidelines for a secure and effective setup in your HVAC system.
Before Installing
- Inspect Filter: Always ensure the filter is clean, dry, and free from any damage or deformation before attempting installation.
- Check Airflow Direction: Locate the airflow arrow clearly printed on the filter frame. This arrow is critical and must point in the direction of the air moving through your HVAC system (i.e., towards the furnace, air handler, or fan).
- Verify Dimensions: Double-check that the filter’s actual dimensions (9 inches × 33.5 inches × 0.1875 inches) precisely match the requirements of your filter slot or housing to ensure a snug fit and prevent air bypass.
- Safety First: For your safety and to prevent damage to your HVAC system, always turn off your HVAC system at the thermostat and the main power switch before accessing the filter compartment.
Installation Steps
- Locate Filter Slot: Identify the filter access slot or housing in your furnace, air handler, return air duct, or range hood.
- Remove Old Filter: Carefully slide out the old filter, taking note of its orientation and the direction of its airflow arrow for reference.
- Orient New Filter: With the airflow arrow on the new AMFCO filter pointing correctly towards the furnace/air handler, align the filter with the filter slot.
- Slide into Place: Gently slide the filter completely into the slot until it is fully seated and flush with the housing. Do not force the filter, as this can bend the frame or damage the media.
- Secure Access Panel: Close and securely fasten any access panels or doors to the filter compartment. Ensure latches or screws are tightened.
- Restore Power: Once the filter is securely installed and the access panel is closed, turn the main power switch back on and reset your thermostat to resume system operation.
Notes by System Type
- Upflow Systems: The airflow arrow on the filter should point upwards, towards the ceiling, indicating air moving from the return to the supply.
- Downflow Systems: The airflow arrow should point downwards, towards the floor, indicating air moving from the return to the supply.
- Horizontal Systems: The airflow arrow should point horizontally, in the direction of the air handler or furnace.
- Grille/Return-Air Installations: Ensure the filter is securely held in place by any clips, latches, or a dedicated frame within the return air grille, with the arrow pointing into the ductwork.
Cleaning and Maintenance for AMFCO Washable Air Filters
The AMFCO HI Series Aluminum Screen Mesh Air Filter is specifically designed for easy cleaning and reuse, offering significant cost savings and environmental benefits over disposable filters. Regular maintenance ensures optimal filtration performance, maintains HVAC system efficiency, and extends the overall life of your equipment.
Washing Procedure
To effectively clean your AMFCO aluminum screen filter, follow these simple steps:
- Remove Filter: Carefully remove the dirty filter from its housing, noting the airflow direction for reinstallation.
- Rinse with Warm Water: Using a moderate-to-heavy stream of warm water, rinse the filter thoroughly. Begin by rinsing against the direction of airflow to dislodge larger, surface-level particles, then rinse with the direction of airflow to flush out remaining debris from within the media layers.
- Repeat as Needed: Continue rinsing until the water runs clear from both sides of the filter. For stubborn grease or heavy buildup, a mild, non-abrasive household detergent (e.g., dish soap) can be applied and gently worked into the media, followed by a very thorough rinse to remove all soap residue.
- Shake Off Excess Water: Gently shake the filter to remove as much excess water as possible. The integrated drain holes in the frame are designed to assist in this process.
- Allow to Air Dry: Place the filter in a well-ventilated area to air dry completely before reinstallation. Ensure it is positioned to allow maximum air circulation. Do not use heat sources (like a dryer or direct sunlight) to dry the filter, as this can potentially damage the aluminum or warp the frame.
- Reinstall: Once completely dry, reinstall the filter into your HVAC system with the airflow arrow pointing in the correct direction.
What NOT To Do When Cleaning
- Do NOT use high-powered steam cleaning: Excessive pressure can damage the delicate aluminum screen media and compromise the filter’s structural integrity.
- Do NOT use harsh chemical dips or strong solvents: These can corrode the aluminum, degrade the filter’s materials, or leave harmful residues that affect air quality.
- Do NOT use abrasive brushes, scouring pads, or steel wool: These tools can scratch, deform, or tear the aluminum mesh, reducing filtration efficiency and filter lifespan.
- Do NOT bend or force the filter: Bending the frame or media can compromise the filter’s seal and structural integrity, leading to air bypass and reduced effectiveness.
- Do NOT reinstall a wet filter: Reinstalling a damp filter can promote mold or mildew growth within your HVAC system and reduce filtration efficiency.
Cleaning Frequency Guide
- Residential Use: Typically every 1–3 months, depending on factors such as household activity, presence of pets, local air quality, and system run time.
- Commercial Use: Every 2–4 weeks, or as indicated by system monitoring, due to higher occupancy, increased particulate load, and extended operational hours.
- Industrial Use (Grease/Mist): Weekly or bi-weekly, especially in kitchen range hoods or industrial processes generating heavy grease, oil mist, or coolant mist, to maintain optimal performance and safety.
- High Dust Environments: More frequent cleaning may be required, potentially every 2–4 weeks, if the filter is exposed to unusually dusty conditions.
