Truck & Equipment Semi Downdraft Paint Booth

Marathon’s Semi Down Draft Series spray paintbooths are designed to be an efficient Space Saving finishing solution. Can be ordered with a Spray & Cure heater or without

Front Air Flow Introduction

The Semi Down Draft Spray Paint Booths are designed so the air enters through the front ceiling where the shop air is cleaner. Air travels thru intake filters and moves horizontally, from the front of the booth to the rear of the booth. This system envelopes the vehicle with clean, filtered air. Over spray from the painting process is then captured by the exhaust filter system in the back wall of the spray booth. All our booths meet applicable national requirements established by OSHA and NFPA for paint booth construction.

AIR FLOW
Intake, heated booth: Outside air is filtered twice, once as it enters through the air make up unit located at the side of the booth, and again as it passes through the intake plenum filters (shown in green). In this example, this booth is equipped with a Spray & Cure heating unit.
Semi Down Draft Airflow Diagram
Intake, non heated booth:
The air is filtered twice, once through plenum side filters, and again through the ceiling filters before entering the work area.
Semi Down Draft Airflow DiagramExhaust: The filtered air travels horizontally across the length of the booth (crossflow). 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.
