With a filter
AstroVac's filter units separate the dust from the air by using a replaceable bag. It is possible, but not necessary, to make a guided exhaust to the outside (through the wall or roof).
In case of an exhaust to the outside a standard dust bag is used.
If you do not want, or are not permitted, to make an exhaust to the outside, then use a high-efficiency dust bag, with a high filter resolution. Dust bags are easily replaceable and have a capacity of 30 liters.
Without a filter
AstroVac's filterless units do not lose suction and are easy to maintain. With advanced cyclone technology, the dust is extracted from the air without using any filter.
Due to the complete absence of filters, slightly more dust (approx. 5%) is vented to the outside compared to a central vacuum unit with a filter. Low-maintenance installations, which do require the exhaust air to be vented to the outside.
