Centac Specification and Performance Data.pdf

This document is a Centac Specification and Performance Data sheet for a Centac Model C-150 (M4-B2) compressor. The specification details include comprehensive technical parameters such as oil reservoir capacity (730 GAL), maximum working pressure, oil temperature ranges, cooling water flow requirements, and critical operational speeds ranging from 13,000 to 29,000 RPM across six stages. The compressor is motor-driven by a General Electric 6900V motor with 5500 horsepower, rated at 1800 RPM with a drip-proof guarded type and 1.15 service factor.

The performance data sheet specifies design conditions including sea level altitude, 15 lbs/sec nominal inlet capacity, 95°F inlet temperature, 60% relative humidity, and a discharge pressure of 735.9 PSIG. The document provides extensive technical drawings and reference numbers for various components, including motor outline, terminal box, speed torque curve, connection diagrams, and performance specifications. The detailed technical specifications suggest this is likely supporting a complex industrial or aerospace equipment maintenance or replacement project, specifically aligned with the Air Force's requirement for a CENTAC 1 Overhaul at Wright-Patterson Air Force Base.
