GAST Regenerative BLOWERS. 

 The industry choice when high oxygen, low energy consumption and reliable service is needed. • 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
• 50 and 60 Hz operation, automatic thermal overload protection, UL approved and
CSA certified, can be mounted in any position, lightweight, durable and compact
• Includes inlet air filter and outlet bleed valve. • 6' power cord on all blowers 1 hp and smaller
Larger and three phase blowers are available — please inquire!
