The Campbell Hausfeld ASME-certified, 30-gallon air storage tank (AR8021) provides extra storage of compressed air for peak-demand situations in pneumatic processes. The air storage tank increases the capacity of the air system to help get more jobs done; it also decreases the number of times the air compressor cycles on and off, which reduces wear for longer system life.
