The Whirlwind R4247 Regenerative Blower is a rugged and dependable regenerative blower and the ideal solution for moving large volumes of air for high volume vacuum or compressed air applications.

The impeller is the only moving part in the R4247 and does not come in contact with the housing channels and is therefore "wear-free".

The R4247 can be mounted in any plane and with a dynamically balanced impeller generates little vibration.
