DS-BM aseptic filter holders are intended for fine and sterilizing filtration of compressed air and gases in biopharmaceutical and other industries, where special requirements to the security of filtration are set.
Filter holders are designed for highly critical applications requiring high degree of treatment and durability of construction.
Fully complete filter holders are intended for installation of single filter element 250 mm height with D-structure with double radial sealing and bayonet fixture. Specially polished inner surfaces minimize adhesion of particles or microorganisms and their accumulation and increases sanitization effectiveness.
The filter holder is equipped with an air bleed valve, a drain valve and a stainless steel pressure gauge.
Standard filter holder is provided with a pressure gauge without the permeator.
