EVEREST, leading manufacturer of Roots Blowers in India, introduces the all new Tri-Lobe Roots Blowers. Tri-lobe technology means blowers have lobe tips exposed to 120 degrees around the rotor instead of 180 degrees as in a bi-lobe blower. This provides a stiffer rotor set, meaning less deflection at any load. These blowers have been designed keeping the specific demands of the industry of continuous duty operation, sturdy design, reduced noise, reduced pulsations and vibrations, longer bearing life and minimal maintenance in mind. Everest Blowers are produced on the latest state-of-art CNC machines from Haas (USA) and HMT (India), thereby ensuring a quality product. These blowers are designed for continuous duty service. Complete package units are shipped with all essential accessories and electric motor, ready to install, on plug and play concept. An Everest Tri-Lobe blower is supplied with built-in safety & monitoring equipment such as safety relief valve and pressure gauge.
Everest Tri-Lobe Blowers/Compressors are positive displacement units, whose pumping capacity is determined by size, operating speed and pressure conditions. It employs two Tri-Lobe impellers mounted on parallel shafts, rotating in opposite direction within a casing closed at the ends by side plates. As the impellers rotate, air is drawn into one side of the casing and forced out of the opposite side against the existing pressures. The differential pressure developed, therefore, depends upon the resistance of the connected system. The Blowers, being positive displacement type, do not develop pressure within the casing but the discharge pressure depends upon the system resistance/back pressure. Effective sealing of the compressor inlet area from the discharge area is accomplished by use of very small operational clearance, eliminating the need of any internal lubrication of the lobes. A pair of accurately machined alloy steel, hardened and ground timing gears maintain clearances between the impellers, during rotation. The air, thus delivered, is 100% OIL FREE. The pumping capacity of a lobe compressor, operating at constant speed remains relatively independent of inlet and discharge pressure variations. These Blowers are constant volume machines, which deliver a fixed discharge against the system back pressure. It is, therefore, essential to ensure that minimum pipeline restrictions, at the inlet and discharge, are imposed. Adequate size piping and large radius bends ensure minimum line losses resulting in higher efficiency and low power consumption. Sudden change in pipeline cross section should also be avoided. To change capacity, it is necessary either to change speed (energy saving) or vent some of the air into atmosphere (not energy saving). The air must not be re-circulated from the discharge to suction as it may result in overheating of the tri lube blower. No attempt should ever be made to control the capacity of compressor by means of throttle valves in the intake or discharge piping. This increases the power load on the motor and may seriously damage the compressor. There is an increase in the discharge air temperature due to heat of compression. As a thumb rule the discharge air temperature increases @ 100C for every 0.1 Kg/cm2 of P above the inlet temperature.
