Air Filters

General purpose compressed air filters remove water and particulate material from the air stream to protect down stream 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.

Pressure Regulators

Master Pneumatic regulators are made in a wide range of sizes to suit nearly all industrial requirements for pneumatic pressure regulation. Good pressure regulation is essential to the efficient use of pneumatic equipment. A compressor may supply air at 150 psig, but most of the equipment will operate best at lower pressures. A cylinder, for example, may develop sufficient force for its purpose with 50-psig air. Remember that compressed air is costly, so using higher air pressure than necessary is wasteful, and may also shorten the life of the cylinder. A general purpose pressure regulator is the answer for greater economy and efficiency.

Regulators are of two basic designs. Piston design provides highest air flow;
diaphragm design provides high sensitivity and quick response. All regulators are self-relieving, but a non-relieving option is available. A pressure gauge is standard, and gauge ports are at the front and the rear of each unit. In addition there are precision regulators in all port sizes for applications demanding extra precision in the regulation of air pressure, plus regulators for remote, external piloting.

Air Line Lubricators

Air line lubricators are designed to introduce atomized oil into the air line so that downstream mechanisms can be adequately lubricated. Lubricators should be adjusted so that the minimum amount of oil to lubricate the equipment is used. Excess oil will simply be blown into the atmosphere and pollute the environment.
There are two basic designs used in Master Pneumatic lubricators: sight-feed design and wick-feed design.

Pressure Valves

Lockout valves are offered in a full range of port sizes, and with different actuation modes. Each valve is de signed to satisfy the OSHA requirements for energy isolation and lockout. They are not, however, intended emergency stop devices. They lock out the supply air in a system with an easy pushing or sliding motion, and also exhaust downstream air pressure. Even after extended periods on standby, the valves are designed with seals and materials that allow the lock out control to move smoothly into the lock out position. All Master Pneumatic lockout valves can be secured in the closed position by means of a padlock so that the valve can not be inadvertently opened to cause a potentially hazardous situation.

Auxiliary Valves

Auxiliary valves are those used in pneumatic circuits to make the major components of the circuit work with greater versatility and efficiency. Flow control valves have an adjustable orifice which restricts the flow of air in one direction through the valve. Free, unrestricted flow is allowed in the opposite direction. Shuttle valves have two inlet ports, but only one outlet port. The inlet port with the higher pressure is automatically connected to the outlet port. This allows an output signal to be initiated from two different locations.

Silencers and Reclassifiers

Silencers and reclassifiers are integral silencer and oil separation devices. When installed at the exhaust ports of pneumatic valves they reduce exhaust noise and capture lubricants contained in the exhausting air. They are used on valve-cylinder applications and on air tools with piped exhausts.

External Drain

The WARRIOR drain is designed to remove condensate from components in compressed air systems. Typical in stallations include compressors, dryers, receivers, driplegs, and filters. The drain consists of a timer and a valve. Electronic controls allow the draining interval to be set from 0.5 to 45 minutes, and the drain time from 0.5 to 10 seconds. Once set, draining action is automatic and requires no maintenance. This is important in constant-flow applications where there is no on-off action to trigger a standard automatic drain.

MPS Pressure Sensors

The MPS sensor has two independent NPN or PNP open collector output signals. An analog output is optional. The Switch Output Mode has a switch point programmed by the user at a specific pressure. The hysteresis range adjustment controls the output signal from 0 to 100% below the switch point. The optional analog output is calibrated to the pressure scale of the sensor.
