The integration of a general purpose ﬁlter and a pressure regulator into a single module provides the compactness needed where space is limited. These integral filter/regulators are offered by Master Pneumatic in port sizes from 1/8" up to 3/4" along with SENTRY models equipped with quick-connect ﬁttings for tubing from 1/4" up to 10 mm.
When an integral ﬁlter/regulator is paired with a lubricator, joined either by a modular connector or a pipe nipple, the assembly makes a complete FRL with nothing lost in performance, but with the advantage of compactness to ﬁt in tight spaces.
All ﬁlter/regulators include an internal automatic ﬁlter drain and a pressure gauge as standard equipment, and regulators are either self-relieving or non-relieving. SENTRY, GUARDSMAN, and SERIES 380 assemblies include a lockout valve for added safety.
Available options are the same as those for the corresponding individual ﬁlters, regulators, and lubricators. They include regulating springs for various pressure ranges, metal ﬁlter bowls, and sintered bronze ﬁlter elements in several µm ratings, as well as quick-ﬁll caps for the lubricators. All assemblies, except Miniatures, now include a lockout valve for increased safety.
