Request Information
Republic offers a complete line of regenerative blowers for high vacuum or compressed air applications in both horizontal and vertical mounted positions. TEFC motors are rated for 50/60 Hz operation and are IE3, cUL, UL, and CE certified. The impeller is directly connected to the motor shaft, providing powerful air force without undue friction. The bearings are outside the compression chamber, ensuring maximum operational reliability under high differential pressure. Constructed in robust diecast aluminum, this low-maintenance, oil-free design provides continuous, dependable service to our customers.

Available Options

N/A All Republic Regenerative Blowers are available in pre-assembled kits for either pressure or vacuum applications. These kits include an inlet filter, gauge and relief valve, and are factory tested prior to shipment. Optional items for these kits include check valve, and tube adaptor; washdown motors, explosion proof motors, or other specialty motors; noise enclosures; and control panels such as VFD's, PLC's, or starter panels.

Note

N/A The performance curves are based on air at a temperature of 59 ºF and an atmospheric pressure of 29.91 inch Hg with a tolerance of ±10%. The total pressure differences are valid for inlet and ambient temperatures up to 77 ºF. Suction capacity relates to inlet conditions. Pressure capacity relates to atmospheric conditions. For other conditions please contact Republic. Three phase motor tolerances are ±10% for fixed voltage motors and ±5% for voltage range motors. Single phase machines are designed with a ±5% tolerance. The frequency tolerance is ±2% maximum.
