The latest Bollfilter type 6.19 automatic backflushing filter is similar to the Bollfilter type 6.18 but it has an additional connection for an external supply of high pressure liquid or steam.

It is design for use where the system pressure is low and cannot provide the energy required for backflushing. An external medium is used to flush the contaminants from the filter during backflushing.

The 6.19 is available with connection sizes from 50 to 400mm, for flows up to 1,800 m3/h. It can be skid-mounted if required.
