Whirlwind STA Series Septic Air Pumps
Whirlwind Septic Air Pumps are linear air pumps that use diaphragms to pump air through the unit. These flexible, rubber membranes are attached on each side of a magnetic actuating rod, or “shuttle.” The pump’s motor utilizes an electromagnetic current to move the shuttle back and forth. This motion expands and contracts the diaphragms, compressing and forcing air through a hose into the liquid effluent of your tank. At the end of the hose is a diffuser, which creates many small bubbles to distribute oxygen throughout the wastewater. This dissolved oxygen (DO) is vital for the aerobic bacteria to break down organic matter in the septic tank.
Whirlwind septic linear air pumps are exceptionally reliable, providing consistent airflow to your septic aeration tank. These septic pumps are compatible to replace OEM brand septic tank air pumps.
The Whirlwind STA150AL septic air compressor comes with a built-in visual/audible alarm to alert you in the event of low-pressure due to weakened diaphragms. Whirlwind linear air compressors have an exceptionally long lifespan, however, over time the diaphragms will weaken and eventually need replacement. The alarm has a light that will illuminate, and a buzzer will sound.
The alarm comes with three settings: Test/Silence/Operate. “Test” allows you to check that the alarm light and buzzer sound work properly. “Silence” allows you to mute the buzzer. This is a convenient feature as it may take a few days before you are able to determine the cause of the alarm and find the solution. “Operate” is the setting for normal use. If the visual/audible alarm sounds in this setting, it indicates that your pump requires servicing.
Easy to Maintain
Whirlwind septic aeration pump motors have no bearings or other moving parts that require lubrication. With this oil-less system, only minor maintenance is necessary. Regularly cleaning and/or replacing the filter is easily accomplished using the hand-adjustable knob located on the top of the pump.
Diaphragms will eventually weaken and need replacement. “Rebuilding” your pump by installing new diaphragms essentially restores your pump to “new” condition.
Quiet, Cost-Effective Aeration
Whirlwind STA Series septic air pumps offer a high rate of aeration while consuming much less energy than most aerators on the market. Amperage is a useful indicator of energy consumption and the STA150AL draws only 2.9 Amps with an open flow of 10.8 CFM.
Another marker of highly efficient machines is noise level. Linear air pumps are known for their quiet, low-cost operation. Durable, anti-vibration rubber feet suppress noise and keep the Whirlwind STA150AL septic aerator firmly in place.
Compact, Weather-Proof Design
Whirlwind septic linear air pumps are extremely compact pumps. With their minimal footprint, they easily fit on top of the septic tank lid. The Whirlwind STA150AL Septic Air Pump is constructed with a lightweight, powder-coated aluminum housing for better temperature handling and corrosion-resistance. STA150AL linear air pumps are safe to install exposed to the elements but can be covered with fake rocks or other properly vented enclosures.
Whirlwind linear diaphragm air pumps are designed to run continuously or on a timer for intermittent use. If you choose a timed option, Septic Tank Parts recommends cycling the pump on a “two hours on/two hours off” schedule and not to keep the pump off for longer than two hours.
The quiet operation, low energy consumption, and small footprint of the Whirlwind linear air compressors makes them desirable aerators for indoor growing systems such as hydroponics, aquaculture, aquascaping, aquaponics, or as air pumps for large aquariums. Whirlwind linear air compressors are also effective pond aeration pumps.
