Medical Instrument Gas is compressed air purified to meet the requirements of the Instrument Society of world as an alternative to Nitrogen. Equivalent to Nitrogen in pressure, dryness, and cleanliness, Instrument Air can support multiple medical applications including driving surgical tools, operating pneumatic brakes and tables, central sterile supply, and laboratory air.
Smaller operations that do not want to have a separate compressors and piping line use pure nitrogen out of cylinders for this purpose.
There are three different compressors that are strongly favored for the distribution of medical air: Scroll, Oil-Less Reciprocating and Oil-Free Tooth Machines. Oil-free and oil-less technology is the preferred method to distribute medical air, because it is the simplest and most cost effective solution.
A scroll compressor works by using one stationary scroll and one moving scroll. The moving one orbits the stationary one to compress the air. The space for the trapped air gets smaller and smaller, decreasing the volume and thereby increasing the pressure.
This compressor type is used in distributing med gas, because required maintenance is minimal, and they operate well in all duty cycles. Scroll compressors are also very clean, quiet, and small, making them ideal for distributing med gas in your hospital or clinic setting.
Scroll compressors are most commonly used for carrying medical gas for anesthesia, to calibrate surgical tools, and to power incubators and ventilators.
