SEP now offers a range of highly cost-effective compressed air regulators, and combined filter/regulators for use with air compressors on pre-action dry, alternate or tail-end systems.

Our regulators conform to ISO6953-1 and incorporate a press-to-lock adjuster with a highly visible red band if they are not locked.

Our high-flow filter/regulators conform to ISO5782-1 and come as standard with 50μm bronze filter (other sizes are available to order).
