Master Pneumatic – The Most Respected Name in Pneumatic Products. For over 50 years Master Pneumatic has been bringing industry the finest in pneumatic products. In addition to our fine products, we are well known for our commitment to customer service and satisfaction. Here are just a few of the reasons why our customers are pleased to deal with Master Pneumatic.

 

WE HELP TO REDUCE YOUR INVENTORY NEEDS

Our “Just-In-Time” inventory program ensures a reliable supply of products to our wide network of distributors. This means that you don’t have to maintain large stocks of parts. If a distributor should ever be temporarily out of any standard product, he can have it drop-shipped directly to you.

ALL OUR PRODUCTS ARE FACTORY-TESTED

Our products are designed, produced and then factory-tested so that they perform properly as soon as they are put into service. This also means that they are built to give you long-term reliability. That is why Master Pneumatic products can be found in large and small plants in all parts of the world.

WHEN PRODUCTS TO ABROAD, OUR SUPPORT GOES WITH THEM

We have been in export markets since 1960. Our products can be specified for overseas plants, or for use on OEM products shipped abroad, with the assurance that they are fully accepted and supported by the worldwide network of Master Pneumatic, such as Pneumatic and Hydraulic located in three key areas; Houston, Lafayette and Baton Rouge.

WE WORK WITH YOU ON YOUR NEEDS FOR CUSTOMIZED PRODUCTS

Designing specialized products to satisfy special needs is one of our recognized strong points. One of our sales engineers will be pleased to discuss any of your unique pneumatic problems and offer a cost-effective solution.

BEST WARRANTY IN THE BUSINESS

The true test of quality by any product is the company belief in that product. That’s why Master Pneumatic offers a SEVEN-YEAR WARRANTY. We are so proud of our warranty, we proudly display on the very first page of our catalog, not on the last page as most of the industry does. The company warrants to the Purchaser that the equipment to be delivered will be free from defects in material and workmanship for seven years.


MASTER PNEUMATIC PRODUCTS OFFERED

Master Pneumatic offers a complete range of air line support equipment, accessories and options to handle every possible need no matter what industry you are in, from medical to oilfield.

GENERAL PURPOSE FILTERS

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 in 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 calm to ensure 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 micron, so that nearly all particles than 5 micron (half the diameter of a human hair) will be collected in the filter element.

Filters come in a wide range of port sizes and flow rates from 1/8” NPT to 2” NPT, with an assortment of options such as high-strength polycarbonate  bowls, metal bowls, manual drains, automatic drains and float drains.

COALESCING FILTERS

Master Pneumatic coalescing filters remove 99.99% of oil and solid contaminants larger than 3 micron. An optional 0.01-micron-rated element provides extremely fine filtration, but at some reduction in air flow. However, in GUARDSMAN, GUARDSMAN II, SERIES 380 AND VANGUARD filters there are available extended bowls with higher capacity coalescing elements for significantly increased air flows.

Coalescing filters have epoxy-resin-coated, borosilicate, glass-fiber elements. Liquids and solids are removed from the air stream by several different actions such as IMPACTION, INTERCEPTION, DIFFUSION AND DRAINING. Available in sizes from 1/8” to 2” NPT, units are available with slide type gauges, dual face gauges, reed switches, internal automatic drains, manual drains and plastic or metal bowls.

PRESSURE REGULATORS

Master Pneumatic pressure regulators are made in a wide range of sizes to suit nearly all  industrial  requirements for pneumatic pressure regulation. Available in 1/8” through 2” NPT sizes, our regulators come in two basic designs, piston design and diaphragm design.

Piston regulators provide the highest air flow, while diaphragm regulators provide high sensitivity and quick response. All regulators are self-relieving, but a non-relieving option is available.

In addition, we offer precision regulators in all port sizes for applications demanding extra precision, with an option 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.

SIGHT-FEED LUBRICATORS

Air flows through a flexible-vane automatic flow sensor that creates a small pressure differential between the air passage and the oil reservoir. This differential causes oil to move up a riser tube, through an adjustable metering valve, and then to drip into a transparent dome and the air stream. This oil is “atomized” by the air stream, and carried down the air line to the points of lubrication.

Sight-feed lubricators are easy to adjust, and an indicator on the sight dome measures the amount of oil dispensed. The adjusting knob can be removed to make the lubricator “tamper-resistant.” All working parts are in an easily replaceable cartridge.

NOTE: These types of lubricators are not recommended for valve and cylinder circuits, where injection lubricators are the preferred method of lubrication.

WICK-FEED LUBRICATORS

In a wick-feed lubricator, one end of a porous bronze wick is saturated with oil in the reservoir. Capillary action causes the oil to travel up the wick. Oil is stripped off the upper portion of the wick by the air flow, and maintains a constant oil-to-air ratio. This ratio can be varied by manual adjustment. Units will not shut off, even with dirt and moisture in the reservoir. However, air must be shut off when filling the reservoirs of these models.

OTHER OPTIONS AND ACCESSORIES

Master Pneumatic also offers other options and accessories to complete the entire air treatment application range such as:
