Standard pre-filters rust and sag prematurely in spray booths and chemical environments due to solvent vapors and paint overspray. The G3 Corrosion-Resistant Paint-Coated Mesh Panel Filter by CHUQI solves this with a heat-cured, baked-on steel grid that firmly secures high-density polycotton media under high airflows.
Corrosion & Rust Defense: Baked-on protective paint coating prevents grid oxidation caused by harsh chemical fumes and moisture.
Non-Deforming Structure: Reinforced mesh support eliminates frame collapse, sagging, and media bypass.
Extended Service Life: High dust-holding capacity captures coarse paint mist and particulates (≥ 5 μm), shielding expensive secondary HEPA/medium filters.
Custom OEM/ODM Dimensions: Available in 21 mm, 25 mm, and 46 mm profiles to fit standard spray booth filter housings.

Designed for aggressive industrial environments, the G3 Paint-Coated Mesh Panel Filter features a specialized heat-cured finish over its steel retaining grid (or optional aluminum mesh). This protective coating blocks oxidation, rust, and chemical corrosion caused by paint fumes and ambient humidity.
Corrosion-Resistant Grid: Heat-cured paint barrier prevents rust and chemical degradation in harsh exhaust setups.
Non-Warping Media Support: Paired with resilient non-woven synthetic media to maintain uniform airflow without fluttering or media distortion.
Slim Profile Fit: Compact flat-panel design slides effortlessly into standard side-access filter tracks for easy replacement.
Heavy-Duty Air Filtration: Delivers a rigid, high-capacity primary barrier for demanding supply and exhaust ventilation systems.

Engineered specifically for heavy-dust, resin mist, and chemical-laden environments, this corrosion-resistant primary filter excels in specialized industrial applications, including:
Coating & Finishing Facilities: Automotive paint spray booth intake plenums, industrial coating lines, and silk screen printing workshops.
Industrial Ventilation: Metal pretreatment plants, chemical processing workshops, and cleanroom fresh air make-up units (MAU).
Its primary filtration role is to trap airborne resin mist, sticky paint overspray droplets, and coarse particulates before they reach fine secondary filters or exhaust blowers.
Proper maintenance ensures consistent airflow and prevents paint overspray buildup in industrial exhaust lines:
Spray Booths & Printing Facilities (High Paint Mist Loading): Perform weekly pressure drop inspections, and replace the filter unit every 1 to 2 months.
Cleanroom Fresh Air Intakes & General Industrial Ventilation: Inspect monthly, and schedule complete batch replacements every 3 to 4 months.
Frequently Asked Questions: G3 Coated Mesh Pre-Filters
Q: Why is a paint-coated mesh grid required for spray booth air pre-filtration?
A: Baked-on paint coating protects the internal steel retaining mesh from oxidation, rust, and chemical corrosion when exposed to paint overspray, solvent vapors, and high humidity, preventing frame structural collapse.
Q: Can this G3 coated mesh filter capture paint overspray particles effectively?
A: Yes. The high-capacity polycotton synthetic media captures paint overspray mist, sticky particulates, and dust fibers down to 5 microns, protecting downstream exhaust blowers and fine filters from fouling.
Q: What frame materials and thickness options are available for this SKU?
A: We manufacture this model in galvanized steel or aluminum frames with standard profile thicknesses of 21mm, 25mm, and 46mm, featuring paint-coated square grid or aluminum face netting.
Q: How does the filter prevent structural deformation under strong airflow?
A: The rigid paint-coated steel grid provides double-sided support to the synthetic media, preventing fiber sagging or blow-through even under maximum operating airflow rates up to 3200 m³/h.
Q: Is this corrosion-resistant panel air filter cleanable or disposable?
A: When exposed to dry particulate matter, it can be cleaned using low-pressure compressed air. However, if heavily saturated with sticky paint overspray or resin mist, complete filter replacement is recommended.
