SEPAERATOR® COMMERCIAL PLUS 120 DETAILS
Hiblow Air Pump
The SepAerator™ uses only top quality air pumps that are designed and proven to run trouble free for many years. The Hiblow air pumps have proven to be high quality and high performance septic air pumps. The Hiblow air pump used on the SepAerator® Commercial Plus 120 package has an output of 5.2 c.f.m. and is effective at treating 750-1000 gallons per day of wastewater or up to a 2500 gallon septic tank.
This air pump will use approximately $4 to $8 per month to operate. The Hiblow air pumps were designed to run continuously and our system works best when operated that way. The average life of the diaphragms in the air pump is 5 to 7 years. The diaphragms are a replaceable part, and Septic Solutions® carries a full line of Hiblow Replacement Parts. If you decide to repair your unit when the diaphragms fail, a pump will last you around 10 to 12 years.
Patented Wonderfuser™ Assembly
The Wonderfuser diffuser assembly is a unique design offered only in the SepAerator™ packages from Septic Solutions®. The Wonderfuser is maintenance free and very effective at not only transfering oxygen into the wastewater, but also breaking down large solids into tiny particles for easier digestion.
The Wonderfuser will be lowered and sat on the bottom of your septic tank on the inlet side. The base of the diffuser assembly weighs 13 pounds to ensure it will sit securely on the bottom. The diffuser is self-positioning, meaning you do not have to mount it in any way, nor do you have to worry about it falling over, as the top of the diffuser is buoyant and will always end up in the upright position.
The SepAerator™ Wonderfuser introduces oxygen some 10 inches off the bottom of a septic tank through a series of 48 orifices angled downward at approximately 35 degrees from top to bottom. When air is diffused in water and bubbles are created, the air bubbles want to travel straight up. The Wonderfuser has a deflection area 15 inches from the bottom that causes all rising air bubbles to be deflected outward 360 degrees around the diffuser. This allows the oxygen to stay in the tank much longer than other systems. Secondly the deflector creates a rolling action in the tank. This rolling action provides a very important function that causes the combined air and water movement to act somewhat like an oversized household blender exploding large solids into tiny particles for easier digestion.
Unique to the SepAerator™ Wonderfuser, by utilizing this deflected rolling action most solids that come into the tank are broken down into very small particles within 30 seconds. When those solids are rapidly broken into small particles that are continually moving inside the tank, aerobic bacteria generated by sufficient oxygen being introduced inside the tank, can quickly and easily attach themselves to those small particles. Much smaller and moving particles can be found and devoured by these aerobic bacteria very quickly resulting in a much higher quality of effluent.
Air Pump Housing and Platform
The SepAerator™ Value Package includes our durable and attractive Air Pump Housing and Platform combination. These from manufacturered from roto-molded HDPE plastic designed to last many years sitting outside in various weather conditions. These products will withstand the strong Ultra-violet rays of the sun, extreme hot or cold weather, as well as keep your air pump out of rain or snow.
At both ends of the Housing are eight inch aluminum vents for adequate pump ventilation. One of the most important things anyone can do to protect their investment in a new air pump is to make sure that air pump does not run too hot. Inadequate ventilation can and will cause pre-mature failure of any air pump.
The SepAerator™ Housing and Platform was specifically designed and built for the sole purpose of protecting and ventilating our air pumps. The Housing has curved edges and a rolling curved top, which adds significantly to its strength.
Heavy Duty Spa-Flex Airline
The spa-flex air line is made up of a very high grade material that is very strong and flexible. Its flexibility allows for easy installation in even the most difficult of circumstances. Simply screw the threaded brass adapter attached to the air line into the fitting in the top of the diffuser. Lower the diffuser into the tank using the spa-flex and even swing it over into position if necessary. Curve the line up through the opening and out the side and then up and into the bottom of the housing where the other end hooks to the air pump. It cannot be much easier than that. This spa-flex can be glued to ½ schedule 40 pvc pipe if you want to extend the pump to a remote location. It is extremely tough and durable ensuring that it will deliver air from the pump to the diffuser trouble free for many years to come.
