All filters have published data that explain the initial and final static pressure (measured in "inches of water column"). When the final resistance is reached, the filter must be changed. A loaded filter that is left unchanged will allow particles to pass through. A blower equipped with a variable speed drive can increase the RPM's to accommodate the changing conditions.
There are many types of filters used in a paint system and we will recommend the best type of filter and also provide a schedule for replacing them. This can be used as a starting point but careful monitoring and data tracking is necessary to develop your filter changing schedule.
