One common feature of most air compressors is the sound of the rushing air – so how can silent air compressors produce a jet without producing that characteristic whooshing noise?

It’s a combination of precision machining, effective lubrication, and extra external noise insulation to absorb the last of any sound that might be produced.

Together, these measures can produce extremely quiet and even silent air compressors, ideal for use in enclosed spaces, such as in small workshops where a quiet-running and economical compressor is preferable.

For obvious reasons, the alternative – an industrial air compressor operating at normal volume levels – would be unwelcome in any workshop where individuals need to use the equipment over a full working day.

The SILENT Series of ABAC air compressors is one choice of silent air compressors, with a one-stage or two-stage belt-driven mechanism producing the jet of compressed air.

Inside the S-Series, noise-reducing foams help to prevent the transmission of any sound between different parts of the system.

And externally, an extra noise insulating cover cuts out the last few decibels that might otherwise escape from the moving parts inside.

Finishing touches like an oil level indicator that can be seen without opening the hood mean there should be no need to expose anybody to unwanted noise, even during some routine maintenance and safety checks.

Meanwhile, Bambi Air Compressors pride themselves on their MD range, which promises to deliver ultra high performance with ultra low noise levels.

The T75 pump unit offers compressed air output 50% higher than other silent air compressors, according to Bambi Air Compressors.

And while the pump is oil lubricated, this does not mean the T75 cannot be used in locations where a very clean compressed air supply, free from oil particles and droplets, is needed.

That is because of the piston rings fitted to the compressor – a feature Bambi say is unique among silent air compressors, and which prevents any oil from passing into the air supply.
