Gaisa kompresors. In today’s modern laboratory, compressed air is required for numerous purposes. An air compressor converts electric power into kinetic energy by compressing and pressurizing air, which, on command, can be released in quick bursts. There are numerous methods of air compression, divided into either positive-displacement or negative-displacement types. Modern laboratory compressors can be extremely quiet and many of them are available with efficient filtration and drying systems. This enables them to provide absolutely clean and dry air for nearly every application.
