Question about Air Tools & Compressors

1 Answer

Howdy, I just acquired an air compressor, ''Westinghouse Air Brake Co., Type Y 3YC, SN 136848. I am wondering about parts motor config, cfm output, psi, etc. It appears to be a 2 stage & I'm thinking it should reach 175 psi or so. Can you assist in the matter? Thanks LT

We have a Westinghouse 3YC air compressor. The safety relief valve in the line between the two compressors started "popping off" recently. The compressor seems to be working fine. Is this a problem only with the relief valve or could there be a symptom of a more serious condition that we should be attending to? The valve is stamped 60 max which I assume is 60 psi. Is this the correct size. The tank pressure is set for125 psi. The tank relief valve is marked 250 max.

If there is no external leakage, then air is probably slipping back past the valves. If the cylinders and rings are good, a valve change may fix it. There are still aftermarket parts available for these machines. As a rule of thumb, a rebuild with rings, gaskets, valves, and bearings usually runs about $100 per horsepower.

I have an Ingersoll Rand Type 30 air compressor. Model #234. I was given this unit because the motor had gone bad. I would like to replace the motor and use it but I was not given the bad motor with the...


One dealer for your model compressor is Northern. They are very good at replacement parts. If you do not have 3 phase power, you could shop around for 5 to 7 hp 220 v motor making sure that the motor mount will align with your plate. Pully size depends on dia. of pulley on the pump. Most pumps turn between 550 min to 1100 rpm depending on the power available and cfm requirements. Most motors turn at 1725 rpm so for example if your compressor has a 14 in. pulley then you motor will need a 5 in. pulley to turn it about 620 rpm. The larger the pulley at the motor the higher cfm produced but more amps used. Motor speed x pulley dia. divided by compressor pulley dia. To obtain more efficiency and highest cfm you will need 3 phase. Good place to see motors and two piece pulley combnations is www.grainger.com. Good luck

Nail Gun how to


One of the factors used to designate compressor power is motor horsepower. However, this isn't the best indicator. You really need to know the amount of air the compressor can deliver at a specific pressure. The rate at which a compressor can deliver a volume of air is noted in cubic feet per minute (cfm). Because atmospheric pressure plays a role in how fast air moves into the cylinder, cfm will vary with atmospheric pressure. It also varies with the temperature and humidity of the air. To set an even playing field, makers calculate standard cubic feet per minute (scfm) as cfm at sea level with 68 degrees F air at 36% relative humidity. Scfm ratings are given at a specific pressure–3.0 scfm at 90 psi, for example. If you reduce pressure, scfm goes up, and vice versa. You also may run across a rating called displacement cfm. This figure is the product of cylinder displacement and motor rpm. In comparison with scfm, it provides an index of compressor pump efficiency. The cfm and psi ratings are important because they indicate the tools that a particular compressor can drive. When choosing a compressor, make sure it can supply the amount of air and the pressure that your tools need.

Portable Air Compressor Comparison


Portable air compressors give flexibility to the job both inside and outside the working environment. They're powered by electric, gasoline or diesel engine. A larger portable air compressor often has its own carrying trailer with wheels and handles. You buy a compressor based on its horsepower, pounds per square inch (PSI) and cubic feet per minute (CFM). Choose a portable air compressor to make work quicker and easier. Figure the amount of power you need based on the type of job and air tools used. Know the cubic feet per minute (CFM), such as 5 CFM for small household tools and 10 CFM or more for wrenches or sanders. All air tools have these ratings. Select a gas- or electric-powered engine. Gas gives a higher reliability for frequent use and portability, but consider electric for enclosed areas for its lack of fumes. Pick an air tank based on amount of use time and tools. Large tanks are best for longer use with sanders or grinders and smaller tanks for less time, like wrenches and air hammers. Consider the pump type you need: belt for heavy use or direct-drive for light home use. The quieter belt-drive pump needs periodic oil changes. Buy an inexpensive, small electric portable air compressor for small jobs. These typically operate from a 12-volt power outlet and inflate a 14-inch tire in a few minutes. Get a 150 PSI, 120 volt motor pancake-type air compressor for home use. These light-use models typically carry two air couplers, allowing hook up of two air tools and adequate 25 feet or more air hose. Obtain a larger PSI portable air compressor for bigger jobs, like nailing, with longer continuous use capabilities.
