Fiberglass panel filters for high-temperature work, built from layered glass fibre media with good chemical resistance.

1. Low resistance with high dust-holding capacity, saving energy.

2. Resistant to chemicals and suitable for high-temperature applications up to 300°C (575°F).

3. Ideal for pre-filtration in ventilation and air conditioning systems of commercial and industrial buildings.

## Key features

- **Continuous temperature**: ≤240 °C (Withstands 300 °C instant peaks in baking ovens and pre-coating stages)
- **Filtration grades**: G2, G3, G4 (EN779) (EU2–EU4 equivalents for the same panel)
- **Fiberglass media**: Multi-layer, random array (Good chemical and temperature resistance in a non-woven structure)
- **Low resistance**: 45 – 60 Pa initial (Rated at 1.0 m/s across the three standard thicknesses)
- **Standard sizes**: 500×500×15 / 21 / 96 mm (Custom sizes available to the holding frame)
- **Final resistance**: 250 Pa (Set the change-out alarm at 250 Pa on the differential gauge)
