With air being used for many applications, some more obvious than others, solving OEM problems with compressed air is easier than you think.

In some parts of the country where piped sewerage is not available and high water tables exist, household waste must be treated aerobically. This means air is mixed into a solution to activate microbes that feed on the waste, speeding up the naturally occurring organic breakdown.

Rotary vane air compressor and vacuum pumps from the Gast Group – a member of the IDEX Corporation – are the perfect solution for these applications and are available with oil-less, oil-lubricated, motor-mounted or separate drive styles.

They provide a long, very low maintenance life; are simple and economical to install and operate; and the low vibration design means that the range is ultra-quiet in operation.

Units offer a wide range of pulse-free airflow rates from 0.31 to 112 cfm (0.53 to 190 m3/h) without the need for a separate receiver tank. Vacuum ratings range from 65 to 335 mbar with pressure ratings from 5 to 25 psig (0.4 to 1.7 bar) and motor outputs from 1/45 to 15 HP (0.02 to 11.1 kW).

Options include dual-function compressor and vacuum pumps, dual-frequency, multi-voltage AC electric motors are available along with, 12 and 24 volts DC-rated models. A range of recommended accessories is also available and bespoke versions can be manufactured to special order for OEM quantities.

As well as environmental and water & waste treatment, Gast’s air compressor and vacuum pump ranges are suitable for sectors including food and beverage processing, medical healthcare, laboratory and for applications as diverse as air sampling, breathing air supplies and vacuum forming.
