Depending on the air pressure that you want to store the other method that I tried and was able to get 35 PSI from was using my old 702 windmill. I mounted a goodyear airbag that trucks use as a shock absorber to the botttom of the tower, on the down stroke of the windmill it would push the airbag open and suck the air in through one check valve. On the upstroke it would squeeze the airbag closed and force the air out through a second check valve into the air storage tank. If you try this method make sure you dont try to squeeze the air out on the down stroke or it will bend and or brake the wooded rod on the windmill. Trust me on this one. Once the tank had about 35 PSI it would stall the windmill

www.windcompressor.com The unit I bought will pump up to 30 CFM at 175 PSI. works great

We bought a windmill air compressor that has a 10 HP compressor and store the air in two 1,100 gallon propane tanks. The 5 blades are over 17 feet long and it works great, started out using it just as a pond aerator but have since switched over some of the electric motors in my shop to pneumatic motors. The Wind compressor is set for 175 PSI. Im in the process of looking for a third storage tank
