The Hiblow HP-120 is a power-efficient septic air pump designed with a linear diaphragm pump. This specific pump contains only an exhaust port, and the inlet air is pulled through an orifice. With thermal overload protection, this standard UL approved 120 VAC model is oil-free and durable. Although it is priced higher than other air pumps, it will prove to be long-lasting and cost-effective—whether it is used continuously or intermittently. You can contact Hiblow USA for custom voltage applications. They provide 48 VDC system applications using external PWM controllers for modulating pump flow.

Hiblow USA serves as a subsidiary for Techno Takatsuki Co., who introduced the first diaphragm pump in 1967. It has since then become the most common type of air pump used for aerobic septic systems. Why is it so popular? A high percentage of solids with varying size can easily be expelled with almost 200 psi discharge pressure, making it strong and efficient. 

Additionally, an aerobic septic system is considered most ideal for the breakdown of organic material in septic tanks. The aerobic, oxygen-loving respiration occurring creates 20 times more energy than an anaerobic system. The oxygen-filled environment of this type of system allows waste to break down faster. Therefore, with the necessary aeration process fulfilled by the Hiblow HP-120 Septic Air Pump, the organic material leaving the septic tank will be considerably lessened, while the amount of clean water produced is increased.
