Maintaining the filter

Spray booth filters need to be maintained to a high standard, as filthy filters will significantly affect the end product. A great way to identify when a filter needs replacing is by using a manometer. This is a useful device that measures the air pressure inside the filter to determine whether your filter needs to be renewed. According to PF Online, it takes a mere couple of particles, or 10 microns, to ruin the finish on your paint job. These particles equate to a miniscule 0.0004 inches!

Regularly checking and monitoring filter usage is a good way to ensure your paint finish remains consistent. The spray painting process is an integral part of the overall protection. It needs to be conducted in a separate room or spray booth, with sufficient ventilation throughout the room. The filters remove nasty toxic fumes, as well as dust and other particles that have the potential to damage the overall paint finish.

Types of filters

It is important to choose the appropriate spray booth filters. There are various types of filter and paint, including input filters, extractor filters, cardboard concertina filters, ceiling inlet filters, fibreglass roll and paper filters. All are useful for different purposes.

Input filters make sure the air that enters the spray booth is clean. This is key to ensure your spray finish isn’t destroyed! They are useful for rooms that don’t have great ventilation. An input filter maintains regular ventilation throughout your spray room.

As spray paint contains dangerous toxins, extract filters are important in ensuring the air leaving the spray room is clean and safe. Sock filters are used with auxiliary drying systems to improve the quality of your finish.

Concertina filters are easily foldable with a big surface filter area, whereas inlet filters covers the flow of air from the ceiling to the flow. A fibreglass roll provides comprehensive filtration, whereas paper filters provide several layers, accommodating many different types of paint.
