Linear Air Pumps Useful Information

Air pumps (“blowers”) generally use a lower amount of power, however do so almost continuously through the year – and the cost can add up.

 

Make sure yours is properly rated with our checklist:

 

MPC Services prides itself on its brand-independent perspective. The strongest compressor brands have earned it through quality product supply and reliability; however that does not always mean it is the best option for your site.

 

Air pumps blow air along the air-hose, the end of which is usually submerged in water. Back-pressure on an air blower measures how hard the pump is having to work to blow air, and can be expressed in metres of water”. It is typically the sum of friction between air and the pipe, and the effort required to push air down into the water.

 

Higher compressor back-pressures usually lead to lower air-flow. Excessive back-pressure can accelerate wear / failure.

The following curves have been selected based on a target air-flow of 50-70 Lpm (litres per minute) at a back-pressure of 2.0m. For a version of this chart customised for your site, contact the team at enquiries@mpcservices.co.uk.

While air pumps generally use little power, because most systems are designed to run continuously, the costs can add up faster than you might guess. The following table estimates cost based on 17p/kWh and 100% on-time.
