Greenco Side Channel Blower

Use the duty point method: add up the air your diffusers need, work out the pressure they need it at, then choose the model whose air flow at that pressure meets the demand with a small margin in reserve.

Allow roughly 10 kPa (100 mbar) per metre of water above the diffuser, then add pipework friction and diffuser back pressure, which together typically add another 5 to 15 kPa.

Both are offered up to 2.2 kW – three phase is generally the better choice where the supply exists because it starts more gently and runs cooler, while single phase suits smaller sites without three phase power.

Yes – both are mandatory: the inlet air filter keeps grit out of the impeller and the pressure relief valve protects the machine if a line blocks, and warranty is only offered where both are installed.

Side channel blowers are noticeably loud and push a lot of heat into the discharge air, so mount them in a ventilated, weather-protected enclosure away from occupied areas and use heat-rated pipework at the outlet.

240 V units come without cable or a three pin plug and 415 V units must be wired on site by a licensed electrician, normally into a control box; a lead can be fitted by request at extra cost on 24 V units only.

Yes – the same 2RB units run in vacuum duty for applications such as vacuum holding and gas sample extraction; tell us the duty and we will confirm the right model.
