Overview
Republic 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 certified for 50/60 Hz operation, meeting cUL, UL, and CE standards. The design features a direct connection between the impeller and 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 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%. The total pressure differences are applicable 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.

Model Specifications
The document provides detailed specifications for models HRC 1302, 1402, 1452, and 1502, including air flow, rated vacuum and pressure, motor power, voltage, current, sound level, and weight. For example, the HRC 1302 model at 60 Hz has an air flow of 771 CFM/1310 m3/hr, rated vacuum of 88 in. H2O/220 mbar, and rated pressure of 80 in. H2O/200 mbar.

Available Kits and Options
Republic offers pre-assembled kits for pressure or vacuum applications, including an inlet filter, gauge, and relief valve, all factory tested before shipment. Optional items include check valves, tube adaptors, washdown motors, explosion-proof motors, noise enclosures, and control panels like VFDs, PLCs, or starter panels.
