1/16/2024 0 Comments Industrial extractor fan![]() Models are available that provide up to 40,000 CFM. This helps remove odors and fumes and keeps the workplace at a more comfortable temperature. Explosion-proof air circulating fansĪir circulating fans are not intended primarily for exhaust or make-up air. Fans with capacities up to 55,000 CFM are available. Belt drive models take up a little more space and need more maintenance. Both belt and direct drive models are available. Tube axial fans are designed for integration into cylindrical ducting. Models are available with up to 55,000 CFM. These supply-side fans incorporate filters in their housings that remove harmful contamination. It's important that make-up air is clean because particulates could affect paint finish quality. Explosion-proof filtered supply or intake fans ![]() Models are available providing up to 15,000 CFM. These fans will mount to a wall or metal panel. Note that filters should be inspected regularly and replaced as needed.Įxplosion-proof panel-mounted wall exhaust fans ![]() Explosion-proof filtered wall exhaust fansĪvailable to handle up to 15,000 CFM, these fans incorporate a filter element to trap particulates that would otherwise be exhausted. Fans in this style are avaialble with capacities of up to 7,500 CFM. This stops wind and rain from entering when the booth is not in use. These fans are mounted to sqaure housings with shutters on the outer surface. Here's more detail: Explosion-proof shuttered wall-mounted exhaust fans We offer fans for both make-up air (supply-side) and exhaust, with and without filters. Types of fansĪll the fans we sell for paint spray booths are explosion-proof. If belt-drive is chosen both belt and pulley must be completely enclosed. NFPA regulations also require fans to be explosion-proof and recommend against the use of belt drive fans. (Filtering make-up air is not mandatory but highly recommended in order to protect the quality of finish being applied.) In most booths they also require filters on the exhaust, sometimes referred to as paint overspray arrestors. In cross draft the exhaust is placed on the opposite wall of the booth to the intake.īoth OSHA and NFPA have strict expectations regarding exhaust outlet location to ensure contaminated air is not drawn back into the booth. In a downdraft booth an exhaust fan installed low down pulls out vapor-laden air while make-up air enters from the top of the booth. Airflow in paint spray boothsīooths are usually configured in one of two ways to provide adequate ventilation. And last, the EPA also has strict regulations regarding spray booth ventilation. ![]() The NFPA 33 standard addresses fire prevention in spray booths while NFPA 70 covers ignition sources such as electrical switches. Effective ventilation prevents vapors accumulating, which happens mostly at floor level, but it's still essential to eliminate all potential ignition sources. Paint vapors have a low flash point and ignite easily. Don't overlook that these fumes may also affect others working or living close by. Not only is that bad for employees but it affects productivity and quality too. These can cause headaches, dizziness and nausea. Paint spraying hazardsĪs paint, especially oil-based paint, dries it gives off fumes. We offer models providing up to 55,000 CFM and are available in many blade sizes. Depending on the type of hazardous chemicals, fumes, gases or dust in the atmosphere, it is important to purchase a fan or blower based on these elements. These fans are typically rated by Class, Division and Group criteria. These highly specialized fans are designed with totally enclosed explosion proof motors, and non-sparking or non-ferrous metal blades. These are explosion-proof for hazardous atmospheres and many incorporate filters. We sell fans designed specifically to meet the demands of paint spray booths. That’s why the NFPA, OSHA and the EPA have detailed requirements for ventilation, and you can’t have good ventilation without exhaust and make-up fans. Paint gives off VOC’s that pose a fire hazard and create health and environmental problems. ![]()
