Septic Solutions® is proud to bring to you the Ultra-Air™ Model 735! The most advanced alternative replacement shaft aerator available on the market today! This new unit has many improved designed features over our previous model and other models available on the market today. All of the components of this product are manufactured right here in the U.S.A.!

The Ultra-Air™ Model 735 motor is designed to give you years of trouble free service. Our durable 1/4 HP, 1725 RPM hollow shafted motor will run smoothly and generate approximately 2.0 cfm of airflow to make your aerobic system work properly. The motor will operate in your system at around 3.5 amps, but has a FLA (full load amp) rating of 4.6 amps. This means the motor will only be working at approximately 75% of its full capacity ensuring a long motor life.

The unique motor shield attached to the top of the motor will cover and protect the motor from any moisture and debris. The built-in handle makes the unit easy to install and remove from the tank. At the top of our motor shield is the air intake for the motor. This air intake allows the motor to draw clean air from outside of the tank down through the handle all the way down through the aspirator tip at the bottom of the shaft and diffuse it into the tank. An O-ring seals the motor shield to the motor ensuring a sealed path for the air to flow through as it travels through the aerator unit.

Our newly designed brackets will provide you with a solid foundation as well as a tight fit inside the riser eliminating the ability for the motor to move back and forth. This will help your motor run more efficiently and last much longer. The brackets are also equipped with rubber feet to prevent vibration noise. The brackets are available in two options: The RED brackets measure 12'' across the top and are designed for a 10'' diamter opening. These brackets are compatible with the Jet Aeration systems. The BLUE brackets measure 14'' across the top and are designed for a 12'' diameter opening. These brackets are compatible with the Norweco Singulair systems.

The stainless steel 5/8'' hollow shaft now has a pressed on brass coupling making for a more balanced fit when attaching to the motor. The shaft is also threaded counterclockwise on the end where the aspirator will simply screw onto it. Since the motor spins counterclockwise you can be assured that the threaded aspirator will always stay tight.

The suds restrictor on the shaft has been enlarged to better protect the motor from the harsh environment inside the tank. This round disc prevents water from splashing or sudsing up towards the motor.

We are most excited about our newly designed Aerodynamic Aspirator. This design will greatly reduce much of the normal drag created when the Aspirator is spinning inside the tank. Our testing shows that the aerodynamic benefit includes reducing the amperage draw of the motor by up to .75 of an amp from 4.25 amps down to 3.5 amps. The importance of this would be that the motor would be operating at less than full capacity meaning it should last longer and use less electricity.

Manufacturer’s recommendations and important information:

It is highly recommended that the ULTRA-AIR™ MODEL 735 septic aerator be allowed to run continuously to provide optimum performance and ensure an adequate oxygen supply is readily available inside the septic tank to proliferate the growth of aerobic bacteria. Do not shut off the motor for extended periods of time if left inside the septic tank.

The ULTRA-AIR™ MODEL 735 aerator comes with a pre-wired 115-volt plug that is designed to plug into a normal electrical socket or for reference an extension cord. The motor draws only 3.5 amps when operating. When mounted into a tank the motor and the suds restrictor must remain above the highest liquid levels inside the tank. At least every 6 months all motors with a shaft inside the tank should be taken out and any debris on the shaft removed. The stainless steel shaft is hollow and attaches to another hollow shaft that extends through the center of the motor. Air is drawn from the vent on top of the tank lid and down through the hollow shafts where it is distributed throughout the tank as defined in the tank illustration. At least once per year the inside of these shafts should be checked to ensure there are no restrictions. Cleaning inside the shaft can be accomplished by using a gun cleaning rod and brush or some other similar means.

Although the ULTRA-AIR™ MODEL 535 aerator has been constructed with Permanently lubricated bearings in a fully enclosed housing, it was not designed to be placed in an area that will flood. Only special flood proof motors will handle flooding conditions. A flooded motor will not be covered by warranty. If potential flooding conditions exist in your application we suggest that you check out our SepAerator™. The SepAerator™ will aerate an existing septic tank without any flooding concerns, as the air pump sits in a housing outside of the tank and diffuses air into the tank through our patent-pending weighted diffuser assembly.
