The 2BH 20540 is the large frame of the Gardner Denver G-BH1 side channel family. It is chosen when a project needs the highest flow in the range while keeping the oil-free, contact-free side channel principle.
Typical duty is continuous aeration of large basins, long-distance pneumatic conveying and central vacuum supply where a smaller frame would have to run at its limit. The two-stage rotor package gives a steep pressure characteristic, so the unit holds its differential when the filter or the pipework gets dirty.
