Andreae Filters

These Andreae Filters – type AF923, are designed to capture any wet solids or liquid particles in the airstream. These include enamels, glues, oils, lacquers, stains, epoxies, tar, Teflon, etc. Filters are constructed from two ply, heavy duty cardboard with a bright white finish, with a final polyester layer

High Efficiency Filters

These High Efficiency Filters combine the proven inertia separation principle of the Eco Filter, but has an additional layer in the form of a polyester media. The V shaped holding pockets retains the paint particulate outside the air stream, and the polyester captures any remaining over spray. The result is a filter with superior holding capacity and exceptional filtration efficiency. Due to this unique combination, static pressure remains constant and the Andreae High Efficiency Filters will last 4-6 times longer than fibre glass Filters

Each Andreae Filter (1 box) measures 900mm x 9.2m (approximately 240 pleats)
