Up to 10 Servo-Meters can be assembled to make up a multiple point lubricator (MPL). The frequency of oil injection can be controlled by using one of the pulse counters or frequency controllers supplied by Master Pneumatic. Series 710 factory assemblies employ two mounting holes. When a very rigid mounting is needed, order Series 720 which employs heavy-duty mounting plates with four mounting holes.

General purpose compressed air filters remove water and particulate material from the air stream to protect downstream equipment from contamination. As air enters the filter, internal baffles create a swirling motion to the air so that entrained dirt and liquids are thrown against the sides of the filter bowl and then fall to the sump area at the bottom of the bowl. Additional baffling keeps the air in the sump area relatively quiet; this ensures that the removed material is not returned to the air flow going to the filter element. The filter element will then collect smaller particles. The most frequently used element in Master Pneumatic general purpose filters is rated at 5 µm, so that nearly all particles larger than 5 µm (half the diameter of a human hair) will be collected in the filter element.

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 filterregulators are offered by Master Pneumatic in port sizes from 18" up to 34" along with SENTRY models equipped with quick-connect fittings for tubing from 14" up to 10 mm. When an integral filterregulator 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 filterregulators 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. Continue »
