Rotary Screw Vacuums

Roto-dynamic air compressors use centrifugal forces which are produced by a rotating component usually a spinning impeller which accelerates then decelerates the captured air and converts kinetic energy into pressurized energy. These compressors include axial and centrifugal compressors.

Rotary screw vacuums

The best Rotary screw vacuum services are gas compressors that use rotation positive displacement mechanism. These compressors are used in large industries as a replacement for piston compressors in cases where very high pressurized air is needed. There are two types of rotary screw vacuums; oil injected and oil free vacuums. Oil-injected vacuums use oils to seal rotors and provide cooling of the gas after compression. The oil is then cooled, filtered and recycled. Oil-free rotary screw vacuums use the screws to compress the air. These have lower maximum discharge and are used in fields where oil recycling is not acceptable or safe such as semiconductor manufacturing plants and medical researchers.

These types of compressors use helica screws called rotors to compress gas. The timing gear in oil-free equipment ensures that the male and female rotors are properly aligned while in oil-injected lubricating oils bonds and bridges the space between the two rotors. This ensures that mechanical energy is transferred between the two rotors as gas enters the pressure side and moves through the rotating screws, the rotors push the gas through the compressor at the end of the screws.

Use of air compressors for medical purposes

Medical gas is fundamental for the proper functioning of a hospital and all other healthcare facilities. As medical and healthcare facilities should observe strict cleanliness protocols, it is also important that the gases used in these facilities are clean of any contamination and foreign particles. This is why most facilities use electric-run air compressors; they are oil-free, easy to run and cost effective. Medical air should be purified to meet the requirements of NFPA and the Instrument Society of America. This compressed air is used in several areas such as running pneumonic brakes and equipment, driving and sterilizing surgical tools and in surgery to keep patients comfortable and breathing.
