I returned to the job site with my new goodies and soon discovered that I had indeed made the right choice. The compressor started right up and was soon pressurized and ready to go. I hooked up the hose and gun, filled the reservoir with stain, and started systematically applying it to the siding. The portable air compressor was on wheels, and easy to maneuver. I could see the dry wood soaking up the stain and I was happy I'd opted for this method of application. I dreaded the idea of having to brush stain on for hours on end. Once I had the first coat on I let it set for a couple hours while I took a break, then went back out and applied a second coat. This probably would have been sufficient, but I had read that the very best thing to do when applying stain with a sprayer is to go back and brush over the job. Doing this really drove the stain into the wood and allowed it to fill every little pore.
Screw compressors consists of two helical rotors which are used in compressing external air to a set pressure, ensuring dry, clean, and compressed air. The find increasing application in segments such as chemicals and petrochemicals processing, food & beverages, metals & mining, automotive, power plants, and oil & gas where large volume of high pressure air is needed especially to drive machine tools.
Now, most of these you do not have to know anything about, but if you are a layman, you can clearly see that there is a lot more to compressors than first meets the eye. For general use with tools, an air compressor is most likely to be a reciprocating piston, a rotary vane or rotary screw compressor.
