Rotary Lube Blower / Vacuum compressor KAESER EB 420 C û 38 m3/min, 53 kPa There are two identical sets of oil-free, 2 lobe rotary blowers, made by Germand Kaeser Kompressoren GmbH in year 2005 with accessories. Manufactures type is Kaeser ED 420 Compact Omega Pluss 53 and accessories include a control cabinet with two inverters and programmable Kaeser Start Control STC 30 unit, totally 6 preliminary intake air filters and 3 final air intake filters with their steel supports. The rotary blower units have removable sound enclose for noise insulation. Operation of the equipment was stopped in year 2007, total running hours approx 7000 and therefore they are in excellent operational condition. In addition, we can offer you service maintenance by the manufacturer at separate cost. This equipment is suitable for demanding dust collection and pneumatic transportation of various products due to oil free operation. For pneumatic transport application some changes in filters and other parts are needed. The rotary lobe has two blower shafts with high efficiency Omega profile in a blower block. The rotary lobe and the block have a very small distance and they are not touching each other's and therefore there is no need for lubrication oil. The rotors are driven by high efficiency electric motor via belt connection and they both are installed on the same base frame. . The inlet and discharge silencers are designed to be effective at all frequencies and are eminently suited to variable speed . Higher rotational blower speeds produce high volumetric efficiencies, which in turn lower discharge temperatures and power consumption. The Compact Range ensures that all serviceable items are accessed from the front panels of enclosures. The preliminary intake air filters are combination of cyclone and bag filter and it removes most of the dust from inlet air. Fine filter is a combination of cyclone and 138 ceramic fine filters which removes fine dust very effectively.
