In modern industrial air management, paint finish operations, and HVAC environmental engineering, Fiberglass Filtration Rolls serve as the baseline defense against airborne particulate contamination, overspray paint mist, and heavy industrial dust load. Designed with a continuous, non-woven glass filament matrix bound by thermo-setting synthetic resins, these media rolls deliver unmatched dust-holding capacities (DHC), flame retardancy, and low structural pressure drops across high-velocity air handlers.
As global environmental regulations tighten—specifically under ISO 16890, EN 779:2012, and EPA 6J spray booth standards—procurement officers and HVAC engineers demand customized, high-gain Original Design Manufacturer (ODM) partners capable of tuning media thickness, fiber strand diameter, density graduation, and chemical resistance profiles for specific application dynamics.
Unlike flat synthetic non-wovens, high-performance fiberglass filtration rolls utilize a progressive density arrangement. The air-inlet side features open, coarse continuous fibers to capture larger particles and paint overspray droplets, while the air-outlet side transitions to an ultra-dense micro-fiber web. This structural evolution prevents surface blinding, maximizing total volumetric dust containment before initial resistance doubles.
Operable up to continuous thermal thresholds of 170°C to 300°C (depending on binder dynamic), glass fiber media withstand harsh industrial exhaust solvents, synthetic paint chemistries, and moisture-laden environments without physical structural collapse, degradation, or off-gassing toxic VOC compounds into the workspace or surrounding atmosphere.

When selecting OEM/ODM fiberglass filtration rolls (commonly designated as Paint-Stop, Floor Media, or Pre-Filter Glass Fiber Rolls), performance verification relies on empirical fluid dynamic testing under ISO 16890 and EN 779 standards. The table below outlines our technical engineering baseline for custom ODM roll production:
| Filter Class (EN779 / ISO16890) | Media Thickness Range (mm) | Initial Resistance @ 1.5 m/s | Paint Overspray Arrestance | Temperature Resistance | Standard ODM Roll Sizes (W x L) |
|---|---|---|---|---|---|
| G2 / ISO Coarse 40% | 20 - 30 mm | 15 - 25 Pa | 93.5% - 95.0% | Up to 170°C | 1m x 20m / 2m x 20m (Customizable) |
| G3 / ISO Coarse 60% | 50 mm | 25 - 35 Pa | 96.0% - 98.2% | Up to 170°C | 0.8m x 20m / 1m x 20m (Customizable) |
| G4 / ISO Coarse 85% | 60 - 100 mm | 35 - 50 Pa | 98.5% - 99.4% | Up to 200°C | 1m x 20m / 2m x 20m / Custom Cut Pads |
| High-Temp Paint Stop | 50 - 75 mm | 30 - 45 Pa | 98.0% - 99.0% | Up to 300°C Continuous | Custom Master Roll Specifications |
For seamless maintenance in industrial spray booths and air handlers, ODM rolls are produced with color-coded side indicators. The air entering side is standard white, while the air leaving side features color tinting (Green/White, Blue/White, or Yellow/White) treated with thermo-fixed chemical backing to lock down individual glass fibers and prevent fiber shedding downstream.
Safety in paint spray operations requires strict adherence to fire mitigation protocols. Our fiberglass rolls satisfy DIN 53438 (Class F1/K1) non-flammability standards. In the event of high temperature exposure or spark contact, the glass fibers act as an inert thermal barrier without sustaining open flames or melting into burning liquid droplets.
As global industrialization advances toward sustainable carbon footprints, major enterprise buyers focus on reducing energy consumption across HVAC networks. Air filtration rolls present direct economic leverage: low initial differential pressure translates directly into reduced fan energy draw in commercial and industrial air filtration units.
Automotive body painting demands zero particle migration to eliminate paint finish craters and fish-eyes. Green/White G3 and G4 fiberglass floor media capture wet paint overspray mist efficiently under continuous floor grid downdraft airflow setups.
Serving as robust pre-filter stages in multi-tier HVAC systems, our fiberglass rolls capture coarse environmental particulates (10µm+), protecting costly down-stream HEPA/ULPA filters from premature dust load degradation.
Combining heat resistance and high chemical inertness, custom fiberglass media rolls prevent reactive ambient chemical aerosol buildup in laboratory fume hood exhaust systems and pharmaceutical production facilities.
Shenzhen Snow Peak Clean Technology Co., Ltd. continuously invests in continuous glass filament technology, binder binder chemistry innovations, and automated quality verification systems. Our R&D roadmap focuses on three strategic vectors:
Transitioning from traditional water-based acrylic thermosetting resins to plant-derived bio-binders. This reduces total volatile organic compound emissions during high-temperature baking processes to near zero, aligning with strict European REACH and RoHS standards.
Integrating plasma nanocoatings onto glass fibers to prevent moisture absorption in high-humidity climates. Hydrophobic glass media rolls maintain structural integrity even when exposed to 99% relative humidity without collapsing or increasing pressure drop prematurely.
Deploying optical and ultrasonic thickness and density mapping sensors directly onto our continuous roll slitting lines to ensure absolute batch-to-batch weight uniformity (g/m²) across every roll shipped globally.
