Rotary vane air compressor kits pump considerably more air than the air pumps. Rotary vane pumps do not operate as deep as the diaphragm and piston pumps — maximum operating depth is 18'. The 1/4 HP model pumps 4.2 CFM of air compared to 1.5 CFM with the 1/4 HP piston compressor. This larger volume of air will increase circulation and oxygen levels for faster cleaning of the pond’s bottom. The 1/4 HP rotary vane kit is recommended for ponds from one to two acres, but it often is used in ponds less than one acre if high fish population, exceptionally poor water conditions or heavy nutrient buildup exists. The 3/4 HP models are recommended for ponds two to four acres while the 1 HP is used in ponds larger than three acres.
