Exhaust, Both Spray Booth Types:

The filtered air travels horizontally towards the front of the booth (cross flow). Finally, the air is filtered of overspray and particulates by the exhaust filters before exiting the booth. Marathon uses standard size intake and exhaust filter media, readily available
from most paint and refinishing suppliers, or directly from Marathon.
