The exhaust fan for a paint booth is a tube axial fan with propeller-style blades. Our fans all use aluminum blades that are best for fire safety because they don’t spark. Non-sparking fans are important for paint booths because most paints and other finishing products are flammable.
Does paint booth need explosion proof fan? NFPA regulations also require fans to be explosion-proof and recommend against the use of belt drive fans. If belt-drive is chosen both belt and pulley must be completely enclosed.
Do exhaust fans need explosion proof? When these combustible materials are present in an environment in high concentrations, they may ignite and cause an explosion. As such, you want to install an explosion proof fan if you operate in a dangerous area where flammable particles or gases are in the air or passing through ventilation systems.
What makes an exhaust fan explosion proof? Explosion-proof fans also use motors that are designed not to produce sparks as they cycle on and off. For added protection, the blades are often made of materials that won’t accumulate static electricity or otherwise become prone to sparking.
How many CFM do I need for a paint booth? Multiply the booth’s face area by 100 feet per minute to achieve CFM. One hundred feet per minute is the guideline for air movement in the booth area. Using the example from above, 80 square feet multiplied by 100 feet per minute equals 8,000 CFM. This is the size of the fan needed.

Why do spray booths operate at negative pressure?
Spray painting booth ventilation relies on the balance of the exhaust fan and the air replacement fan. If just the exhaust fan is on, the booth takes on negative pressure, since more air is being removed than pushed in.
How often should paint booth filters be changed?
“Paint booth exhaust filters need to be changed every 100 operating hours or every three to four work weeks. Anything beyond that is putting your equipment at risk. Each paint operation is different, which may require changing exhaust media more frequently than every 100 hours.”
Does a spray booth need ventilation?
Modern paint booths need to be designed in such a way that they can filter out all the flammable gases and move all the air towards an extractor fan so that there is proper ventilation.
How do I know what size exhaust fan I need?
