EasyPro is please to offer their own line of rocking piston air compressors, each one designed specifically for the demanding job of 24 hour operation. They are ideal for pond aeration systems. The oil-less design safely aerates ponds with no electricity in the water. The sore mounted compressor sends air through tubing to a bottom mounted diffuser for a safe, effective way to aerate ponds. Compressors are available in 115v or 230v.
