Custom Width Fiberglass Filter Rolls for Spray Booth Floors

Introduction: Custom width fiberglass filter rolls work only when the media width, thickness, and roll length match the actual floor grille and the airflow path it serves. The first time a booth designer measures a floor grille for filter media, the assumption is usually that a roll is a roll. Then the numbers come in. […]

How Paint Booth Filter Media Affects Exhaust Fan Pressure Drop

Introduction: Paint booth filter media changes exhaust fan pressure drop by adding resistance as overspray accumulates, shifting airflow and fan load away from the clean-filter operating point. In a spray booth, the exhaust fan is selected to move a certain volume of air against the resistance of the whole system. The floor filter media is […]

Solvent Resistant Fiberglass Media for Industrial Paint Booths

Introduction: Solvent droplets, weak acids, weak bases, and bake heat each press on fiberglass floor filter media in a different way, and knowing which force does what makes material comparison far easier. Air leaving an industrial paint booth rarely behaves like ordinary dusty air. Overspray arrives as microscopic droplets of coating and solvent, and in […]

Thermally Bonded Glass Fiber Media for Paint Overspray Capture

Introduction: Thermally bonded glass fiber media stays fluffy and resilient, and that structure is what lets it capture paint overspray through its depth instead of only at the surface. When a spray booth exhaust filter is pulled for inspection, the fiber web often still looks open even though it is coated with sticky, solvent-loaded paint. […]

Fiberglass Paint Stop Filter Rolls for Spray Booth Floor Exhaust

Introduction: A fiberglass paint stop filter roll is the unframed floor layer that catches overspray before exhaust air reaches the fan and ductwork. In most downdraft spray booths, the first consumable a new technician meets is underfoot. The floor exhaust grille is covered with a fibrous mat, usually off-white and increasingly blotched with paint after […]

How to Size Custom Paint Booth Filters for Nonstandard Exhaust Openings

Introduction: Sizing custom paint booth filters begins at the exhaust opening, not with a catalog number or last year’s roll. A standard roll may cover a nonstandard floor opening yet leave bypass edges, bunch against the support grid, or make replacement harder than it needs to be. Treat the media as part of the exhaust […]
