These blowers do not include inlet air filter or bleed valve, which are necessary for safe and effective operation. Ideal for replacement applications where filter and bleed valve already exist. Gast Regenerative Blowers are the industry choice for high oxygen output, low energy consumption and reliable service. Blowers have only one moving part – the impeller – and since the impeller touches nothing, there is no wear, no seals, no vibrations and no lubrication to be done!
