Air Flow – Modified Down Draft Spray Paint Booth

Intake, Heated Booth:

Outside air is filtered twice, once as it enters in through the air make up unit (heater), and again as it passes through the rear intake plenum filter wall. In this example this booth is equipped with a Spray & Cure heating unit.

Intake, Non Heated Booth:

Outside air is filtered once, through the top intake filters before entering the work area.

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.
