How often do I need to change/clean the air filter?
Most linear air pump manufacturers recommend cleaning air filters every few months and at least once every six months. To clean, remove from the unit, and wash using mild, soapy water and air dry. Do NOT re-install the filter unless it is absolutely dry. Generally, it is recommended to replace the filter annually.
What size air pump do I need for my septic tank?
This is a common question that homeowners have when they find their septic aerator/pump has failed. The best initial step is to determine the make and model of your current pump and locate a compatible replacement. If you know your tank manufacturer, visit the Aerobic Systems page on our website for pumps that are direct replacements for your aerobic septic system.
Manufacturers of linear air pumps follow standard specifications with numbers like 60, 80, 100, 120, 150, 200 etc. indicating the size system it can treat. The Whirlwind STA60N can treat 60 LPM (liters per minute) and the STA80N treats 80 LPM, and so on. These numbers also correlate to tank size.
Do I need to install my Whirlwind Septic Air Pump in an enclosure?
The Whirlwind linear air pumps are designed for high temperature tolerance and moisture/corrosion resistance. For the longest pump life, we recommend installing linear diaphragm pumps in a vented enclosure above ground level to combat high ambient temperatures and reduce exposure to water and dirt.
What is the difference between a linear piston air pump and a linear diaphragm air pump?
Linear piston and diaphragm air pumps are both types of positive displacement pump. Positive displacement pumps move air physically between different chambers and mechanically compress the air to increase the output pressure. The main difference between the two is simply the mechanism used to move the air. Piston pumps use a plunger-like rod to push air, whereas diaphragm pumps use rubber membranes that flex back and forth to pull and push air. The design of these pumps allows for a constant flow making them exceptionally suited for septic, pond, and other aeration purposes.
How long do linear diaphragm air pumps last?
Several years, if properly maintained. Regular septic tank pumping is the most effective way to keep your aerobic septic system healthy and your septic tank pumps and aerators functioning as designed. Other maintenance items, such as regularly replacing the air filter and installing new diaphragms, will keep your septic tank pump aerator performing for years.
What size air hose is used to connect my Whirlwind septic air pump to an alarm?
We install our Whirlwind STA low pressure alarms using a clear, vinyl hose with a ¼” OD (outer diameter) and a 1/8” ID (inner diameter) that fit over the hose bib. The air hose will need to be secured with a hose clamp or a zip tie.
What size hose is recommended for installation of the Whirlwind septic air pumps?
Our Whirlwind STA Series Septic Air Pumps come with a 90-degree rubber elbow fitting that has an ID (inner diameter) of 5/8” to connect the pump to an air line.
My Whirlwind Septic Air Pump alarm has gone off, what does this mean?
If you have a Whirlwind AL model with an alarm or have an alarm installed remotely, it will likely alert you with an illuminated red light and/or a buzzer. This alarm is designed to let you know when the pressure drops below a certain PSI, i.e. low pressure. This is not necessarily an indication that your Whirlwind air pump is broken, but it does likely mean that you need to replace the diaphragms in your pump. If the diaphragms are cracked, the pump can no longer maintain the seal necessary to compress/pressurize the air. The outgoing pressure needs to be enough to overcome the friction inside of the pipes, tubing, and any fittings between the pump outlet and the septic tank.
What size pump do I need to aerate my pond?
Determine the surface area and depth of your pond to find the appropriate pump for your aeration needs. The chart below is a handy guide for selecting a Whirlwind air pump model for your pond:
