Medical Air Systems
99% of all new Medical Air Compressors utilize an
oil-less compressor. These compressors use "no-oil" whatsover, using
sealed bearings and teflon rings.
NFPA-99, 2002 edition now requires that the dryer
be able of maintaining a dewpoint of 32 degrees F. This basically
eliminates the use of old-fashioned refrigerated dryers. Desiccant dyers
should be selected with a 'purge saver' circuit that prevents unnecessary waste
of valuable medical air.
Dewpoint and Carbon Monoxide monitors are
required.
