A spray booth is a specially designed enclosure used to house spray equipment and isolate expelled vapor that is generated during a spray application process.
What temperature should a spray booth be? In the automotive industry, it is no secret that increased throughput equals increased profit. That is why proper temperature settings for paint spraying are so important. For waterborne paint, the recommended booth temperature is between 70 and 75 degrees, or 5 degrees above ambient temperature, whichever is greater.
How much airflow does a spray booth need? Reply: Table G-10 of 1910.94(c)(6)(i) specifies the required airflow velocities ranging from 50 to 250 linear foot per minute (fpm) into the openings of a spray booth for various operations and designs, except where a spray booth has an adequate air replacement system.
What temperature is an automotive paint booth?
A paint booth must be a minimum of 55 degrees Fahrenheit for automotive paint with a catalyst to dry. For paint booths with an air heater, the rule of thumb in the automotive industry is that for every 15 degrees above 70 degrees, a coating will cure about twice as fast (assuming 50 percent relative humidity).

What do you need for a spray booth?
Spray booths should be constructed of steel, concrete, or masonry, and securely and rigidly supported. Interior surfaces should be smooth, continuous, and non-combustible. Sprinklers, visible gauges, and alarms should be properly installed. Booth should be designed to sweep air currents toward the exhaust outlet.
Is a paint booth positive or negative pressure?
A slightly positive booth pressure prevents dust and dirt from being pulled into the paint booth, while a slightly negative pressure may be recommended so vapors cannot escape the spray booth and contaminate other work areas. The paint booth pressure is related to airflow.
What is good cfm for a paint booth?

How does heated paint booth work?
All of the air passes through the pre-filter, then through the burner or around the heat exchanger. The outside air is heated to the desired cure temperature, as defined by the booth controls. The air passes through the intake filters, enters the paint booth and is evenly distributed throughout the cabin of the booth.
What are 3 different types of spray booths?
