Long Term Storage Requirements 2) Cover the unit completely to exclude dirt, dust, moisture, and other foreign materials. 3) If the motor can be moved, it is suggested that the entire motor be encased in a strong, transparent plastic bag. Before sealing this bag, a moisture indicator should be attached to the side of the motor and several bags of silica-gel desiccant put inside the bag, around the motor. When the moisture indicator shows that the desiccant has lost its effectiveness, as by

Description COMPRESSOR The Vilter Single Screw Compressor is a positive displacement, capacity and volume controlled, oil fl ooded, rotary compressor which uses a single main screw intermeshed by two opposing gate rotors. Gas compression occurs when the individual fi ngers of each gate rotor sweep through the grooves, or fl utes, of the main screw as the screw rotates. Compression occurs from the time the screw fl ute is fi rst closed off by the gate rotor fi nger, until the time when the screw

Description The Vilter compressors feature the exclusive Parallex™ Slide System, which consists of a pair of slides for each gate rotor assembly. These two independently operated slides are referred to as the capacity slide and the vol- ume ratio slide. On the suction end of the screw, the capacity slide moves to vary the timing of the beginning of the compression process. With the slide moved all the way out to the suction end of the screw (the 100% position), the compression process begi

Foundation Introduction Vilter Single Screw compressor units are low vibration machines. Under most conditions, no elaborate foundation is necessary. However a sound foundation maintains motor alignment and proper elevation, and is therefore required. Provided are recommendations for the foundation and anchoring of the compressor unit. The Vilter foundation sup- ports the entire operating weight of the unit and is suitable for years of continuous duty. Included are specifi cations for concrete

Foundation Building the Foundation Use the Vilter General Arrangement (GA) and foundation drawings to help secure a building permit and foundation construction. The Vilter GA drawing will have the necessary dimensions required to determine the overall founda- tion size and where to locate the compressor unit on the foundation. It will also show the dimensions required to form up the housekeeping piers that the compressor unit rests on. The Vilter foundation drawing lists the necessary informa
