Like the basket prefilters, they are installed in hydraulic systems before the electric pumps and are suitable to provide a pre-established, fine filtering degree (micron values). Available in different types and versions, they are produced in AISI 304 and AISI 316L stainless steel.

The mobile mesh filtration bag, which has a standard filtering degree of 50 micron or 100 micron, is positioned and secured inside the basket, which is also mobile, by means of the bag fastener with pressure spring.

Special models are also available, with perforated sheet metal secured internally and mobile bag only.
