The Hiblow HP-120A is very similar to the Hiblow HP-120LL. The major difference between the two models is that the HP-120A has an alarm built into the body of the compressor and the HP-120LL has a tap for an external alarm sensor. The Hiblow HP-120A can be used in a 750 GPD aerobic septic system. Ponds that cover an area of up to one acre with a maximum depth between 8 and 10 feet can be aerated with this product.

Rebuild kits are available for the maintenance of this product. This product can be expected to require rebuild after three or four years of operation, and it can be rebuilt two to three times. However, red dust building up inside the compressor may signal that a rebuild may not be sufficient.
