Charles Austen Blowers FAQs
How do I know which Charles Austen blower is right for my sewage treatment plant?
The correct model depends on your treatment plant's make, model and population size, as each plant is designed around a specific air-flow rate. Check your plant's manual or data plate for the original blower specification, or get in touch with our team with those details and we'll match you to the right ET, ET A or ET AO unit. Fitting an undersized or oversized blower can affect aeration efficiency and shorten the life of both the blower and the plant.
What's the difference between the ET, ET A and ET AO ranges?
The ET range is the standard blower, delivering reliable air output with no extra features. The ET A range adds a built-in alarm that alerts you to a fault or failure, such as a blocked diaphragm or loss of pressure. The ET AO range goes a step further with both an alarm and an output cable, allowing you to connect an external beacon for a visible warning if you're away from the property.
Where should a blower be installed?
Blowers should be sited in a dry, well-ventilated location close to the treatment plant, ideally under cover to protect against rain and direct sun. They must never be submerged or allowed to draw in damp air, as this can damage the internal diaphragm and motor. Many installers house them in a small vented cabinet or utility area to keep noise down and protect them from the weather.
How often do Charles Austen blowers need servicing?
Most manufacturers recommend checking the diaphragm and air filter annually as part of your general treatment plant maintenance. Diaphragms are a wearing part and typically need replacing every couple of years depending on usage, so keeping spares in stock is sensible. Regular servicing also helps you catch problems early, before reduced aeration starts affecting treatment performance.
Can I replace my existing plant's blower with a Charles Austen model?
In most cases, yes — Charles Austen blowers are widely used as like-for-like replacements across many popular sewage treatment plant brands. You'll need to match the air-flow output and connection type to your current unit, so have your existing blower's model details or plant specification to hand when choosing a replacement. If you're unsure, send us the details and we'll confirm compatibility before you order.
Are Charles Austen blowers noisy, and will they disturb neighbours?
These blowers run continuously, but they're designed to operate quietly compared with older-style compressors, and noise levels are generally low enough not to cause a nuisance when properly housed. Siting the unit in a ventilated cabinet or enclosure, away from bedroom windows or boundary fences, will further reduce any audible hum. If noise is a particular concern, it's worth checking the decibel rating listed for each specific model before you buy.
