Oil-free air compressors
To meet the demand for clean, dry instrument-quality compressed air for chromatography in the food laboratory, a range of JUN-AIR oil-less air compressors offer an unrivalled combination of low noise levels, reliability, long life and low maintenance.
The compressors are suitable for most types of gas chromatography. GC uses only a small amount of gas – usually zero air or zero nitrogen, and in order to supply the base level of air used as a flame gas or carrier gas for zero air applications, the compressor needs to be fitted with a dryer/scrubber to remove hydrocarbons/CO2. Most chromatography applications use oil-less compressors and with decibel ratings as low as 47 dB (A) when housed in attractive soundproof cabinets, this oil-less range has the lowest noise levels available, making the compressors ideal for installation within laboratory environments and even in or near individual work-stations.
To ensure the highest air quality throughout the lifetime of the compressor, receivers are internally powder-coated to avoid corrosion. Adsorption dryers remove moisture to ensure 100% dry, clean oil-free compressed air, with pressure dewpoints of -40 and -70 ° C. The dryer is located upstream of the receiver so the receiver only stores dry air. Units feature a unique cooling system and wear-resisting piston rings, and are designed for 100% continuous operation up to 10 bar maximum pressure.
