The ventilation system must be running at all times.
Paint booth air flow regulations.
The acgih guidelines and consensus standards criteria are typically recommended when there is no osha criteria addressing a particular problem.
If you want uniform air distribution throughout the booth you should size the air intake filters accordingly.
Osha states that paint booths must be designed to filter out flammable contaminants and move air currents toward an exhaust for proper ventilation.
The real issue with air flow in a spray paint booth is having adequate air.
This requires a building at least 17 472 sq ft with 15.
There must be some sort of independent exhaust system in place to discharge outside of the building.
Additionally vs 75 04 allows the designer to further reduce the airflow rate to 50 cfm ft 2 when the cross sectional area in a drive through booth is greater than 150 ft 2.
Aside from these minimum requirements for paint booths there are some essential safety practices to make sure your booth is maintained properly.
Controlling the paint booth air flow going into the booth with relation to the air being exhausted from the booth is critically important to maintain the proper flow of air over the item being painted and remove the over spray effectively.
Fans to push and pull the air being pushed in and pulled out are done with two types of fans.
A 14 wide x 9 tall x 26 long spray paint booth will exhaust at least 13 104 cubic feet of air per minute.
If you make the filter section too small you can expect turbulence in the booth and this will cause paint overspray to settle on the walls ceiling lamps etc.
Restrict access for anyone with asthma allergies and respiratory illnesses.
Running this spray booth for twenty minutes requires 262 080 cubic feet of available air.
Keep your spray booth clean and change filters regularly.
