Overview
The document provides detailed specifications and features of the DRT series of dry-running rotary vane compressors offered by Republic Manufacturing. These compressors are designed for oil-free applications and are suitable for continuous operation across various industries such as environmental applications, water treatment, aeration, electronics, conveying, and printing.

Specifications
The DRT series compressors are single-stage, air-cooled, and direct-driven. They are available in different models with varying displacements ranging from 5 to 92 CFM (10 to 158 m3/hr) and a maximum pressure of 21 psig. The noise levels range from 72 to 85 dB, and the weight varies from 153 lb (69 kg) to 322 lb (146 kg) depending on the model. The compressors operate at speeds of 1450 rpm for 50 Hz and 1740 rpm for 60 Hz.
