The MK28 vacuum unit by AstroVac filters the dust from the air. 1-motor split system, with unequalled suction power. Making a guided exhaust to the outside (through the wall or the roof) is possible, but because of the perfect filtration of the MK28 it is not necessary.

When exhausting to the outside a standard dust bag can be used. Is it not possible or not desirable to make an exhaust to the outside? Then replace the standard dust bag by a high-efficiency dust bag, with extra high filter resolution. The dust bags for the MK28 are sealable, quick and hygienic to exchange and have a capacity of over 30 liters.
