These High Efficiency Air Blowers are positive displacement twin lobe compressors suitable for a wide range of operating speeds to meet the exact capacity. EVEREST, pioneers in blower technology, have developed EXPO series twin lobe positive displacement Roots blowers having unmatched quality & performance. They have been specially designed for continuous applications, demanding constant flow at varying discharge pressures, such as in E.T.P., Pneumatic Conveying etc. Complete package units are shipped with all essential accessories. The outboard position of rotor bearings allows atmospheric venting between the compression chambers & the bearings which keeps the gears & bearings cool and prevents contamination of compression chamber & air making delivery 100% Oil Free. Compact design, heavy duty bearings and accurately machined tolerances allow high speed operation, increasing capacity for relatively low unit weight.
SPECIAL FEATURES: • Suitable for various gases such as air,town gas,natural gas,nitrogen,hydrogen,carbon dioxide,inert gases,etc. • Positive displacement machines with constant volume characteristics. • 100% oil free compression. • High precision helical timing gears for reliability and long life. • Overhung V-belt drive for all operating and pressure ranges. • Dynamically balanced rotating components to ensure vibration free operation. • Solid,noise absorbing construction in grey cast iro
