Full Down Draft Breakout

The Full Down Draft Spray Paint Booth is designed so the air enters through the ceiling intake filters and moves vertically, from the top of the booth to the bottom of the booth, enveloping the vehicle with clean, filtered air. Overspray from the painting process is then pulled down through the floor grates and captured by the exhaust filters underneath. Marathon’s paint booths for trucks and equipment Full Down Draft Series are designed to be a True Down Draft finishing solution, so a pit or basement required! This booth type can be ordered with a Spray & Cure heater or without. You can also choose between a single wall booth or a fully insulated, double wall booth.

Outside air enters through filters mounted in the ceiling, then travels through the work area. This type of design does allow for the addition of an Air Make Up unit (AMU), so heating (and/or cooling) are available options. The air travels vertically (down draft) through the booth.

Exhaust: Once the air has traveled the height of the booth, the overspray and particulates are removed by the exhaust filters under the grates that cover the pit. This booth has a pit beneath the booth that serves as an exhaust plenum. Marathon uses standard size intake and exhaust filter media, readily available from most paint and refinishing suppliers.
