GRAVITY AIR STEAM STERILIZERS
**************************************************************************
NOTE: Do not return condensate from units located
so far from steam boiler that it is uneconomical.
Only jacket steam condensate is reusable.
**************************************************************************
Gravity air steam sterilizers shall be suitable for sterilization of heat
and moisture stable instruments, supplies, flasked liquids, and utensils,
utilizing steam saturation as the sterilizing agent. Unless otherwise
scheduled, gravity air steam sterilizers shall conform to the applicable
provisions of AAMI ST8. The following shall be included:
a. [Automatic controls] [Microcomputer controls, with cycle
documentation via strip recorder for each cycle. Microcomputer
controls must allow for programming chamber aeration cycle at same
temperature as sterilizing cycle, adjustable from 1 to 59 minutes, 59
seconds. Controls should be designed to facilitate mounting at
location up to 15,000 mm 50 feet from sterilizer].
b. [Sterilizer condensate assembly for condensate to waste] [Steam
supply line on unit fitted with provisions for condensate return line].
c.
Electrical characteristics: 120 volt, 60 Hz, single phase.
d. Materials handling accessories, including two loading cars and two
transfer carriages for each car.

**************************************************************************
NOTE: Do not return condensate from units located
so far from steam boiler that it is uneconomical.
Only jacket steam condensate is reusable.
**************************************************************************
Steam sterilizers shall be suitable for sterilization of heat and moisture
stable instruments, supplies, flasked liquids, and utensils, utilizing
steam saturation as the sterilizing agent. Chamber evacuation of prevacuum
sterilizers shall be by mechanical means or steam flush. Steam sterilizers
shall conform to the applicable provisions of AAMI ST8, except as otherwise
specified. Testing for floor loading type sterilizers shall conform to
applicable provisions of AAMI ST8, as they apply to a size 5 unit with the
