The Bosch PES Flat Pleated Filter is a replacement filter designed for use with Bosch GAS 35 and GAS 55 dust extractors, maintaining consistent suction and filtration performance between service intervals. Constructed from polyester (PES) with an additional nano-coating, this flat pleated filter is engineered to handle ordinary fine dust across dust classes L and M.

Note that it is not suitable for use with acids, oils, or very fibrous media.
