Put together by Sheldon Sportings Goods. I guess they are a refurbished military compressor used for the flamethrowers. I have a 88 CF tanks but seem to exhaust it over the weekend. My fill center is only open on the weekend and so I get a late start on Saturday and I am unable to shoot during the week if my tank is low. Trying to decide whether to buy an additional tank or get a compressor. Concerned about dry air with the Omega.
