Hiblow HP-120LL Applications

The Hiblow HP-120LL is used on many 750 GPD and some 1000 GPD rated NSF Class 1 Standard 40 aerobic treatment systems (ATUs). The Hiblow linear diaphragm septic air pumps are widely regarded as the highest quality and longest lasting septic air pumps available on the market. They are extremely quiet and very energy efficient. The Hiblow HP-120LL can be used for septic tank aeration as well as an aerator for small ponds and water gardens.

NEW LONG LIFE (LL) MODEL

The new Hiblow HP-120LL is an improved long life version of the Hiblow HP-120. The original Hiblow HP-120 would average around 2-3 years of diaphragm life. This new and improved Long Life version should see around 5 years out of diaphragms in most applications.

SEPTIC AIR PUMP SIZE DOES MATTER

A common misconception is that the air pump just puts air in the water, so it doesn’t really matter which size is used. Nothing could be further from the truth. Air pump sizing is actually very important to the operation of your system, and not every system will use the same size air pump. If you have been our website, then you already know there are many different types and sizes. The air pump size is normally determined by the volume capacity of the tank, the style of air diffusers in the tank, and how many GPD (Gallons Per Day) the system is designed to treat.

Our sales team can make sure you get the right size pump if you are unsure about this aspect of buying a new one. In most cases we only need either the model number of the pump you are replacing, or the brand of your aerobic system and the GPD that it is rated to treat. Again, size does matter and it is very important that you get the correct air pump for your system.
