Our innovative concept of partially enclosed encapsulated rotary screw compressors is the outcome of a special design aimed at reducing the user’s maintenance costs. Rapid and easy access to all components means that these compressors can be serviced more quickly than any other screw compressor. The new SILVER compressors are partially enclosed (<67 db/a noise levels) and feature TEFC drive motor, WYE Delta Starter, ASME coded air receiver, and synthetic compressor lubricant as standard equipment. The SILVER compressors, in the new compact and reliable version, are easy to transport and to install.
