I began out my woodworking career with a quarter-sheet electric sander, rapidly graduated to a arbitrary orbit electric disk sander and eventually seen that I really could significantly limit sanding time having an air hand sander. I settled on a 5" Dynabrade sander and Sears 3HP air compressor. It took me less than an hour to realize my error: The little compressor I bought could not start to steadfastly keep up air requirements of the air sander. It'd run out of air stress very nearly straight away and the air sander could slow down to the stage of being useless. I'd then have to wait for many moments for the stress to develop again to get yet another moment of sanding.
To produce matters worse, I'd three persons employed as sanders and so I will have to keep three machines operating at top rate all day long. Used to do some math and learned that I would require a twenty power air compressor with a sizable tank to accomplish this. I was fortunate to locate a applied one for not an excessive amount of money but it needed three period power and plenty of it. Additional money sought out for an electrician to line it as much as the building's 208 volt 3-phase power. The large air compressor was so noisy maybe it's heard all around the making and down the block but it driven these three sanders from dawn to dusk. What's promising is that it taken care of itself in stored sanding time really quickly.
Air sanders are aggressive and efficient. They're gentle in weight Air compressor when compared to their lesser electric cousins. My sanders took to them straight away and manufacturing took off. I was as pleased as they were. Soon there was yet another machine form air compressor needed having large levels of air in the shop: an Onsrud inverted green router. It had been also good to have the ability to strike sawdust of benches and machine while washing upon the shop at the end of the day. The compressor was also applied to spray completes on the finished furniture.
Decades later, I created a smaller woodworking shop within my house which just needed one air sander operating at a time. For that shop, I ordered an air compressor half the size and remote in a soundproof room in one single part of the shop. I ran ¾" galvanized tube underneath the shop floor to three regulators at three various easy locations. The equipment I ordered for that shop as a 5 HP Ingersoll Rand design having an 80 quart tank. At the 80 PSI needed by my Dynabrade sander, the compressor could produce enough air all day long. I must claim that that compressor was perfectly built. All I'd to accomplish was keep an eye on the fat level in the sight glass. During the night, I'd turn fully off the grasp air device quietly of the equipment, making the electricity on, to stop the compressor for the night.
I must assume that, having study this far, you have some interest in having an air compressor to power air resources in your shop. Most likely, a 2-stage reciprocating air compressor will load the needs of a tiny to medium shop. As a principle, a 5 HP air compressor will power one air sander, a 7.5 HP machine will power two and a 10 HP machine is likely to be needed for three sanders.
How big the compressor's air tank is a significant factor: Small the tank, the more often the compressor will have to period on and off, That is difficult on the engine and compressor pump over time and it employs more electricity. I would not also contemplate an air compressor applied to power an air sander with less than the usual 60 quart tank and I'd sense significantly more comfortable having an 80 quart tank.
The kind of electric power needed by an air compressor is yet another consideration. If you have three-phase power offered at your local area, fine. Three period motors tend to make use of electricity much more efficiently than single-phase motors. Big air converters will all require 3-phase power however the 5 HP models come often way. If you do not have 3-phase power accessible, you are able to production it with a rotary or electric period converter as Used to do within my smaller shop. Whether you use single or three period power, you will be needing 230V AC power for single-phase motors and 208 or 220V AC for the three-phase variety. Be sure to check always the voltage and amperage demands of any air compressor before you buy it. Electricians could be expensive.
