Product catalog summary
Overview
Republic Manufacturing offers a comprehensive range of regenerative blowers suitable for high vacuum or compressed air applications. These blowers can be mounted in both horizontal and vertical positions and are equipped with TEFC motors that are CE certified for 50/60 Hz operation. The design features an impeller directly connected to the motor shaft, minimizing friction and enhancing air force efficiency. Bearings are positioned outside the compression chamber to ensure reliability under high differential pressure. The blowers are designed to be low-maintenance and oil-free, providing continuous and dependable service.

Performance Specifications
The performance curves are based on air at 59°F and atmospheric pressure of 29.91 inch Hg, with a tolerance of +/-10%. These specifications are valid for inlet and ambient temperatures up to 77°F. Suction capacity is related to inlet conditions, while pressure capacity is related to atmospheric conditions. For conditions outside these parameters, Republic should be contacted. Motor tolerances for three-phase motors are +/-10% for fixed voltage and +/-5% for voltage range motors, while single-phase machines have a +/-5% tolerance. Frequency tolerance is +/-2% maximum.

4RC520, 121 m3/hr, 3 Phase, 50Hz-1

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 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. This low-maintenance, oil-free design provides continuous, dependable service to our customers. PERFORMANCE Vacuum Total Pressure Difference 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. ©Republic Manufacturing
