The EFS Series provides filtration and silencer for discharge of dry pumps such as dry scroll and screw type pumps. The multi-stage noise reducing features includes a final stage sound absorbent insert. Typical noise attenuation depends on vacuum pump and application but can provide a dampening effect of up to 13 dba. Construction is corrosive resistant black powder coat carbon steel. Operational orientation can be horizontal or vertical.
