Choosing the correct filter for your paint booth.

Your choices will have a direct impact on everything from the efficiency of your paint booth and the quality of the end product to spray booth maintenance costs and the safety of technicians. This guide will introduce you to and give insight into the different types of filters found throughout your spray booth, as well as maintenance tips to keep it running efficiently. We can also provide the filters for your booth.

Establishing a schedule for changing intake and exhaust filters is just as important as deciding which filters to use. The cleanliness of your spray booth and the work you do within it depends heavily on it. Clogged or overloaded filters may not allow proper airflow through the paint booth, causing dust or overspray to recirculate through the booth and affect the finish of your paint job.

Ensuring your paint operation meets the health and safety standards required by the NFPA (National Fire Protection Association) and OSHA (Occupational Safety and Health Administration) is also essential. In more severe situations, clogged filters may create flammable or explosive conditions within your paint booth.

With so many different styles and brands of filters, they reach their target reading and require replacement at varying rates. These rates also depend upon the paint type, paint booth design, fan speed, temperature, and spray equipment.

One way to establish a change-out schedule for exhaust filters is to compare readings from a manometer or Magnehelic pressure gauge with the paint booth manufacturer’s specifications. Without a pressure gauge, it is best to establish a strict maintenance schedule based on the daily spraying volume. Ultimately, it is best to work with your spray booth manufacturer or filter supplier to design an effective schedule for changing your filters that balances filtration needs and cost efficiency in your paint booth’s performance.
