For the people who want a more powerful model, there is Westward 4B220 portable air compressor. This machine uses a powerful Briggs engine. Its powered by a powerful 5.5 HP motor. The machine uses a 2 cylinder pump made of cast iron. It has a horizontally placed tank which has a rated capacity of 20 gallons. It uses a four cycle aluminum block engine. The machine has 21 oz engine oil capacity and 12 oz of compressor pump oil. The machine uses a time tested reliable type H tank which makes it one of the longest performing and most reliable machines that you can buy.
I recommend that you buy a compressor with an air tank. It produces constant air flow, unlike the diaphragm model, which creates pulsation. You have to choose as large as possible reservoir tank. It provides constant, smooth air flow.
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.
