Master Pneumatics breathing air assembly 350-4SA447 is designed to provide breathing air for up to 2 workers. The Breathing Air assembly can allow end users to achieve "grade D" breathing air as defined by the Compressed Gas Association's commodity specification: G-7.1 (www.cganet.com). The general purpose filter in this assembly removes gross contaminants while the coalescing filter removes oil mists, aerosols and minute particles. The adsorbing filter effectively eliminates odors from freons, alchohols, esters, keytones and up to 99 percent of most hydrocarbons. The CO monitor is designed to detect and alert user to the presence of CO if the level is 10 ppm or greater as stated in OSHA title 29 section 1910.134(D)(1)&(2) ANSICGA standard G-7.1

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.

SERV-OIL SINGLE POINT UPSTREAM LUBRICATOR:The single-point lubricator (SPL) is specically designed to lubricate air tools. It cannot be used for general lubrication of components other than air tools. An SPL is installed in the air supply line upstream of the air tool. When the tool is cycled the SPL injects a precise amount of oil at the air inlet of the tool. Both the amount of oil and the frequency of injection are adjustable. Flow Valve: The air suppy line is connected to the inlet of the flow valve. 18-Inch nylon tubing is connected to the nozzle in the outlet port, then runs inside the air line to within a short distance of the air tool.(Note: A check valve must be installed on the end of the 18 nylon tube.) When the air tool is at rest, no air flows in the valve. When the tool is triggered the differential pressure across the sensing disk opens a passage to the pulse counter. Pulse Counter: When the air tool is triggered the pulse counter receives an air signal from the flow valve. A three position switch on counter is set to allow air signal to proceed to the Servo-Meter on every cycle, every 5th cycle or every 10th cycle. This is one of the means of controlling the amount of lubrication that will be supplied to the air tool. Servo-Meter: The servo-meter is an air-actuated, positive displacement oil pump. It injects oil with each signal from the pulse counter. To actuate the servo-meter the signal received must have a pressure of at least 60 psig (4 bar). When actuated a precise amount of oil is delivered to nozzle in the outlet port of the flow valve, and is then carried by a nylon line to the air tool. A transparent sight indicator on one end of Servo-Meter gives visual verification of oil delivery. Adjusting Knob: By means of the adjusting knob on the end of the Servo-Meter, oil delivery can be reduced in precise increments from the maximum rating down to 10% of the maximum rating (30% for 2 drop units).

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

Modular assembly and mounting. Threaded ports or quick-connect fittings for tubing up to 10 mm in diameter. 0.3-m-rated coalescing filter element; optional 0.01-m-rated element. High-strength polycarbonate plastic filter bowl; optional aluminum bowl. Internal automatic drain; optional manual drain. NPTF port threads; optional BSPP threads. Application Note: A general purpose filter must be installed ahead of a coalescing filter to ensure good performance and to extend the life of the coalescing element.

The adsorbing filter is designed to remove vapors from the air line that cannot be removed by a coalescing filter. It produces air free of oil and hydrocarbons as required by industries such as food processing, electronics, and instrumentation. An adsorbing filter preceded by a coalescing filter and a general purpose filter constitute a Clean Air Package.

The integration of a general purpose lter 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 ttings for tubing from 14" up to 10 mm. When an integral lterregulator 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 t in tight spaces. All lterregulators include an internal automatic lter 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 lters, regulators, and lubricators. They include regulating springs for various pressure ranges, metal lter bowls, and sintered bronze lter elements in several m ratings, as well as quick-ll caps for the lubricators. All assemblies, except Miniatures, now include a lockout valve for increased safety. Continue
