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 bearing which keeps the gears & bearing 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.
