The Hiblow HP 80A is a compatible replacement for the Gast SPP-80, Thomas 5078 and 5080, and many other 80 LPM air pumps. The Hiblow HP-80 is commonly used on many 500 GPD systems. Hiblow Aerators, Hiblow Septic Air Pumps, and Hiblow HP Models are the highest quality septic air pumps used on aerobic septic systems today. The Hiblow Diaphragms last longer than any pump on the market. HiBlow Linear Septic Air Pumps all have a low power consumption, quiet operation, little vibration, low pulsation, long life, and are easy to service.
The Hiblow HP-80A has a built in alarm to alert you when the pump has lost pressure. This feature helps you become aware of a problem with the diaphragm or the unit it self so it can be rebuilt with a Hiblow HP-80 rebuild kit. Hiblow septic air pumps can generally be rebuilt twice. So if you are looking at this pump because yours stopped working it can probably be rebuilt and it's very simple to do.
