Air Intake Filter Screens

Air intake filter screens are mounted on the fresh-air side of air handling units, louvers or make-up air systems to stop larger contaminants before they enter the ductwork. This model uses a rigid metal mesh pack inside a metal frame, so instead of changing disposable panels every time the intake gets dirty, the screen can be taken out, cleaned and put back in service.

Typical uses include AHU fresh air sections, intake grilles on rooftop units, and factory make-up air in workshops or spray areas, where dust, insects, fibres and light debris would otherwise plug coils or overload finer filters.

 

Material: Stainless steel or galvanized metal mesh

Frame: Aluminum or galvanized steel frame

Mesh Size: Adjustable (typically 0.5mm to 2.0mm)

Filter Efficiency: Up to 80% for particles ≥5µm

Airflow Resistance: Low pressure drop (≤50Pa)

Humidity Range: 0% to 95% RH (non-condensing)

Dimensions: Customizable (standard sizes available)

Exact values can be adjusted to match your project. When you send an inquiry, you can specify mesh opening, frame material, face size and airflow so we can recommend a suitable configuration.

Installation

Check the frame size and airflow direction before installation.

Slide the screen into the intake frame or track, making sure all four sides sit square and tight.

If the frame uses clips or fasteners, lock them so the screen cannot move or rattle during operation.

After installation, confirm there are no visible bypass gaps around the panel.

Cleaning & Reuse

Inspect regularly according to site conditions (from monthly in dusty environments to longer intervals in cleaner locations).

When the screen is visibly loaded or when pressure drop reaches your internal limit, stop the fan and remove the panel.

Clean with water (and mild detergent if needed) or use compressed air from the clean side outwards.

Allow the screen to dry fully, then reinstall in the same position.

With sensible cleaning intervals, a washable air intake filter like this can remain in use for a long period before physical wear and tear calls for replacement.

To make it easier for international buyers to plan projects and stock, we provide the following typical commercial terms for air intake filter screens:

MOQ (per size)

Standard sizes: normally 50–100 pieces

Custom sizes: normally 100–200 pieces, depending on mesh and frame structure

Sampling

Sample production: about 3–7 days after size and construction are confirmed

Samples can be shipped by express for fit check and on-site testing

Lead Time for Bulk Orders

Standard models: around 15–20 days after deposit

Customised designs: around 20–25 days, confirmed per order

Trade Terms & Payment

Common Incoterms: FOB Xiamen, CIF main ports, DAP for some regions

Payment: T/T (e.g. 30% deposit, 70% before shipment); L/C negotiable for larger contracts

Port & Logistics

Main loading port: Xiamen, China

Packed in export cartons, with pallets or wooden crates used for larger screens

HS Code (reference)

Usually classified under 8421.39 for gas filtration and purification equipment (final classification subject to local customs rules)

1. AHU Fresh Air Intakes

Mounted in the fresh-air section of air handling units

Keeps insects, leaves and visible dust out of coils and drain pans

Used in office buildings, hotels, hospitals, malls and public facilities

2. Factory Make-Up Air & Plant Ventilation

Installed on intake grilles for factory or workshop ventilation systems

Helps protect downstream filters in machining shops, fabrication plants and general manufacturing

Works well where dust levels are higher and intake filters need to withstand rough conditions

3. Spray Booths & Surface Treatment Areas

Used at air intakes for spray paint lines and surface treatment zones

Screens off fibres and coarse dust that would otherwise land on wet coatings

Easy to remove and wash between production runs or when contamination builds up

4. Commercial Parking Garages & Utility Rooms

Fitted on outdoor intake openings for car parks, generator rooms and utility spaces

Helps prevent paper, leaves and loose debris from entering ducts and fans

Suitable for areas where maintenance teams prefer a simple, washable screen that can be checked during routine inspections

We actively participate in key global trade shows annually to showcase innovations, build partnerships, and stay abreast of industry trends: At ISH Frankfurt (the world's top HVAC&R expo), we launch next-gen metal mesh filters-like high-temp models for industrial use-and host tech seminars, driving 20% EU market growth. At HVAC&R Expo (USA), we highlight UL-certified, energy-efficient filters with on-site wash-reuse demos, securing 15+ bulk orders yearly from U.S. clients. The Canton Fair (China) lets us display our full range, engaging buyers from 80+ countries and converting 30% of leads into long-term partnerships. At Interclima (France), we present CE/RoHS-compliant, low-energy filters, adding 12+ new EU partners yearly. These shows blend demos, expert talks, and negotiations, turning global exposure into tangible business growth.

A Sri Lankan customer delegation recently visited our company for a two-day visit and exchange. The delegation toured the production workshop, R&D center, and quality control laboratory, inspecting the entire production process and gaining an in-depth understanding of our corrosion-resistant metal treatment process and automated pleating technology.

 

During the exchange, the two sides discussed topics such as HVAC system filtration requirements in tropical climates and optimizing filter durability in high-humidity environments. We demonstrated the high-pressure washing and reuse process for stainless steel filters and specifically demonstrated a dust filtration solution for tea plantation workshops. The customer highly praised the product's temperature resistance, recyclability, and ISO 9001 quality control system, and reached a preliminary consensus on customized sizes and localized after-sales service.

 

This visit deepened the customer's understanding of our company's technical strength and laid the foundation for future cooperation in the South Asian market.
