3M Adflo Pre-Filter 5 pcs

On the outside, the Adflo turbo unit is covered by a sheath with replaceable spark arrestor. The filter mantle protects the special filters that can be applied only to Adflo, and holds them in position. The pre-filter prolongs the service life of the particulate filter. The particulate filter is for high-efficiency filtration of particles. The gas filter can either be A1B1E1 or A2 that cleans the air of organic-and non-organic substances as well as acidic gases and ozone. Rather than installing a special air filter instead of the gas filter, it is now possible to make a special order, which removes unpleasant smells.
