Our PROCART B pleated spray booth filter is ideal for using with both water and solvent-based paints as well as many other types of coating, including lacquers, PVA, and paint, in all types of dry spray booth. This Procart spray booth filter is designed to filter all types of water and solvent based paints and other types of coating but not powder paints or dust (for this we recommend the use of our Procart M2 or Procart H booth filters). With this design of paper filter your overspray is captured on both on the face of the filter and within the folds which allows the booth air to pass through the filter with minimal obstruction until full, thus a constant, smooth airflow is maintained for much longer than using other types of extraction filtration. What is so important about airflow? Without it you don't have a proper functioning spray booth and you won't be able to produce a proper finish so a good airflow is vital to the running of your spray booth.
