The HEMLA-80 provides simple and reliable aeration for your aerobic septic system, fish tank, or small pond. While some aerators use rubber diaphragms, Medo’s aerators use pistons to push air. That allows Medo’s aerators to avoid the need to periodically replace torn diaphragms. Furthermore, Medo’s units have a reputation for being robust and reliable.
This particular model has an alarm build into the unit. If there is a problem with the pressure leaving the aerator, a lamp and buzzer will signal that there is a problem. Customers do not need to worry about setting up a pressure switch, buzzer, or a light. Medo’s HEMLA-80B has already taken care of all of that already! All the customer needs to do is connect the aerator to the air line and plug the aerator into an outlet. It really is as simple as that!
If the alarm is triggered, the unit is either experiencing too much pressure or too little pressure. Clogged diffusers can cause too much pressure to build up in the air line. On the other hand, a cracked air line would cause too little pressure and trigger the alarm.
It is recommended that the diffusers be inspected before a new aerator is installed. Diffusers are porous devices that are in the water within the septic tank. In order to help oxygen dissolve into the water, diffusers turn the stream of air from the aerator into many small bubbles. However, diffusers can get clogged over time, and that makes it harder for the aerator to push air into the system. Cleaning or replacing the diffusers helps to ensure that you will get the most out of your aerator.
