An exhaust fan is compulsory to accomplish Correct spray booth airflow.
When you are designing a spray booth, it is fundamental that the Correct magnitude of airflow is available. A spray booth should hold an exhaust fan that is rated at the Correct cubic feet per minute (CFM) adjudjing to certify that airflow is always at the optimal scale. While defined equipment is available that can test the concentration of specific solvents, the National Fire Protection Association's estimated sufficient airflow velocity of 100 feet per minute can be used to calculate a sufficient CFM rating for your exhaust fan.
Instructions
1. Use a tape measure to determine the height and width of your spray booth face in feet.
3. Multiply the area by the National Fire Protection Association airflow figure of 100 feet per minute to receive the CFM needed for an exhaust fan in the spray booth. For example, our example of a 100-square-foot area would need a fan with a rating of at least 10,000 CFM to adequately ventilate the booth.
2. Multiply the height and width together to receive the area in square feet. For example, a 10-foot by 10-foot face would have an area of 100 feet.
