Questions & Answers
Question : Should an Air Compressor blow off excess pressure at the crankcase?
I have a used 2 stage air compressor powered by an 5hp electric motor via a drive belt. The compressor is a two stage, it has a V shaped pump with one large and one small cylinder head. The large cylinder head has a small metal line coming from the top of the head, comes down and enters the crankcase via a fitting. The small cylinder head also has a line coming from the top of it's head and comes down and enters the through the side of the crankcase. The fitting that connects this line to the crankcase blows out air when the compressor is on. A friendly know-it-all said it was supposed to be this way to blow off excess pressure, but that doesn't make sense to me. Should this line (about the diameter of a metal brake line on a car) make an airtight seal where it enters the side of the pump crankcase or is this fitting designed to blow off excess pressure inside the crankcase?The compressor does shut off when psi reaches 100. The fittings on the line in question are tight. There is a threaded hole in the side of the crankcase, a square fitting with threaded rounded corners fits between the crankcase and the line coming from the secondary cylinder. I thought I once read that the crankcases on some air pumps are pressurized to reduce piston blowby, and I can see this being used for that, but if that's the case it seems there shouldn't be a strong blast of air coming from the fitting on the side of the crankcase. Again, it's a round hole with a square threaded adapter, and because you have a square inside a circle, you have open space around the side of the square for air to escape. This is the way we got the compressor, so I don't know if this is the way it came or someone just didn't have the right parts to repair it at one time. TY
Answer:
Yes, this compressor is operating correctly. Some compressors operate with automatic stop/start controls, which shut the compressor off when the proper pressure is reached. Other compressors have constant speed controls which uses a pneumatic (air) control line connected to a device which will hold the intake valves open to prevent more air pressure from building up once the desired pressure has been reached. This type of compressor will run in an "idle" mode when it has reached the proper pressure, and it will go back to normal compression mode when the pressure drops. Also, some larger compressors have the ability to bleed off the pressure from the top of the cylinder upon shutting down, so that the compressor motor will not have to start up under a large load. Unless you are simply talking about a loose fitting, there does not seem to be a problem with your machine.

Question : Where do I take an air compressor to get repaired?
I have an air compressor that can't build up any pressure. The pump runs, but the pressure stays near zero. I can't figure out where to take it for repairs. I've called a lawn mower shop, a pump repair shop, and an electrical repair shop. None of them work on air compressors. Any ideas?
Answer:
1 look in owners manual..they have service/repair places listed or # to call2 no book? yahoo/google search the neme brand3 phone book4 unless its a 500+ priced compressor its usually not worth repairing..

Question : How does the sound amplification using just an air compressor or a flame work ?
More than 100 years ago, there was almost no electronics. There were no amplifiers. The achieved amplification using two different methods. One was by just air compressor and other was to use gas light flame; Any ideas how exactly it was done. And by what factor amplification was achieved ?
Answer:
You modulate the opening of a small valve, and you get a large modulation of gas flow. If the gas burns as it comes out, you get further amplification because a small fuel flow produces a much larger exhaust flow.

Question : What is a good safe level to set my air compressor when dusting computers?
I got tired of spending $10+ a month on canned air, so I bought an Air Compressor and the nozzle attachment with a trigger. I was told not to allow the compressor to shoot out too much air because it may damage the computer parts. What is a safe level to set the compressor (PSIs)?
Answer:
This is too good a question to pass up, so here goes,You either have a thousand computers to clean or you are in a terrible location (dust wise).So I figgered, heck, you can always use the compressor to use a pneumatic jackhammer when the dust gets so packed that ya gotta use it to loosen the petrified dust.Talk about over stocking mechanical supplies for something simpler.That's like getting a bulldozer to dig a small hole in the sand.;-)

Question : Air Compressor?
Thinking of buying a air compressor to run air guns like roofing nailers or framing nailers. Wondering if anyone had any ideas?
Answer:
There are many different types of air compressors out there. The more portable ones are only going to have a capacity of a few gallons. If you are running 1-2 guns you will probably be fine. If you are planning on using a lot of pneumatic tools at the same time you might want to step up to a 25 gallon or more. Not as portable, but you can set it up on a jobsite and run multiple lines off it. You can get one of those starting at 250 dollars depending on where you shop. You can get package deals that come with a nailer, but those are portables. I would get a compressor with a direct drive and go oilless. Easier to maintain, if you use it heavily, drain the water out of it daily.Tank capacity has everything to do with peformance. Try running a pneumatic drill with a portable air compressor for more than 5 seconds. If you look at the specs on your air tools it will tell you the minimum tank capacity required to operate your tools.

Question : What kind of air compressor should I be looking for?
I need to buy an air compressor for filling tires. I want something strong enough to deliver air quickly, like a shop air compressor, but not so large that it's unwieldy and high maintenance. What should i look for? Is it true some compressors can shoot out oil or moisture through the hose, and into the tire? The gas station that I go to can inflate tires about 1 psi a second on a 235/65 16 tire. I'd like to have something near this performance.
Answer:
you could go to home depot and get a little five gallon tank air comp that would probably do pretty good...good luck

Question : How much oil is needed for my air compressor for the first time?
I have a MotoMaster 5-gallon air compressor. I need to fill the part with oil so that it is inbetween the red circle. I have already used one bottle, and it is barely half way there. This is my first air compressor, so how much oil do i need to put in for the first time?
Answer:
It depends and it should tell you in the manual. But get more oil and fill it to where it should be and start er up.Happy New Year

Question : What kind of air compressor can fill up a average nitrogen tank?
I am thinking about getting a nitrogen tank so I can play during the winter. I have a air compressor but i want to know if it could fill it up.
Answer:
no average compressor will be able to fill a nitrogen tank to the pressure that you will want, the most amount of pressure that you would be able to get is around 150

Question : What value is there in air compressor tank sizes?
If I bought a 2 gallon air compressor or a 200 gallon air compressor, what is the difference, why is it important?I understand that the compressor would have to run more often on a smaller tank, but is this a bad thing?
Answer:
By having the sure volume of air you can operate your tools better, say your blowing out a water sprinkler system, the 2 gallon of air will not do it as theres not enough air to clear the pipes, and the compressor running will not deliver enough volume to do the job, same as an air tool that takes 90 psi to run, having 200 gallons of air will run the tool say 5 min without waiting for more air to run the tool, and the 2 gallon would only turn the tool for say 15-20 seconds before you have to wait for more volume of air to pump up..............
