GUANLIN waterproof oil-proof anti-static filter bags, 130°C, for humid and oily dust in food and metal processing.
Triple-defense polyester filter bags combining water repellent, oil repellent and anti-static properties for humid, oily and combustible dust streams.
Description
Three problems tend to arrive together in real baghouses: humidity that wets out the felt, oil that glues the dust cake to the surface, and static that turns a spark into an explosion. Treating them one at a time means three different products. GUANLIN triple defense media combines a fluorocarbon impregnation with a conductive grid in a single polyester felt.
Why Choose GUANLIN Triple Defense Filter Bags
- Water repellent — fluorocarbon impregnation stops the felt wetting out in humid gas.
- Oil repellent — oily dust releases cleanly instead of gluing to the surface.
- Anti-static — conductive grid dissipates charge for combustible dust service.
- 130°C service — polyester base media for room temperature duty.
- ≥99.9% efficiency — dense needle felt captures particulate down to 1 μm.
- Custom sizing — Ø115–200 mm × 1000–6000 mm.
Application Scenarios
Food processing with humidity
Wash-down areas and steam-laden exhaust blind ordinary felt; the water repellent finish keeps the cake dry.
Metalworking with oil mist
Cutting oil and coolant carry-over is repelled instead of blinding the media.
Woodworking with resin
Resinous dust sticks to untreated felt; the oil repellent surface releases it.
Coal and chemical powder
Anti-static construction for combustible dust with grounding.
Coastal and humid climates
Ambient humidity no longer shortens bag life.
Mixed duty baghouses
One media covers humidity, oil and static at once.
