Abstract
This invention comprises a method and apparatus for sterilizing air to be used for such things as pneumatic medical instruments, respirators, cabins for aircraft, clean-rooms, and other such environments where bacteria and germ free air is required. The apparatus is comprised of three chambers with an air inlet and an air outlet. In the second chamber air is heated to approximately 200°C and passed through a replaceable filter. The outcoming resultant air is 100% sterilized.

In one embodiment of the present lnventlon, contamlnated compressed alr clrculates at an average pressure of 100-150 psl and a flow rate of approxlmately 100 cfm through a flrst chamber, passlng through a flrst channel.
Thereafter, lt enters a second chamber comprlslng a ceramic cartridge fllter through whlch alr ls forced and heated to 200~C by an electrlc element colled around the cartrldge fllter. Sterlle alr then enters a thlrd chamber located between the flrst and second chambers and travels its way out through the air outlet to pneumatic instruments. In so doing, hot air ln the thlrd chamber gives off lts heat to alr ln sald first chamber. At the bottom of the unit a screwlng lld ls provlded for fllter replacement.
In the preferred apparatus of the present invention three chambers fit within each other. The first chamber is bounded by the outside wall of the apparatus. The first chamber is the air entry chamber. The second chamber ls the sterlllzatlon chamber comprlslng the ceramlc cartridge filter and the electric band which fits around the ceramlc fllter.
The thlrd chamber, called the exhaust chamber, flts between the flrst and second chambers and gives off its heat to the incoming air in the first chamber to thereby lmprove the efflciency of the devlce. The devlce ls also provlded wlth channels whlch allow air to flow between the first and second chambers, and then between the second and thlrd chambers.
Although the lnventlon ls prlmarlly constructed for use wlth compressed alr, the apparatus and method of sterlllzatlon can be used ln any sltuation where there ls a pressure dlfferentlal whlch will move the alr from the lnlet through the sterilizatlon devlce to the outlet. For example, alr from an alrcraft passenger compartment can be clrculated through the devlce and back lnto the passenger compartment.
The apparatus can also be used to sterillze exhaust alr from blohazard test chambers or blohazard contalnment facllltles.
The heat source to effect the sterilization can be ln many forms. For instance, a tubular heatlng element colled around a fllter can be used alternatlvely. A heat cartrldge located wlthln the fllter, or an electrlcal heat band located outslde of and around the fllter could be used. The heat source could also be ln the form of hot alr produced from the turblne englnes of a ~et alrcraft, or the nuclear reactor of a submarlne.
Numerous types of fllters can be used as long as they are capable of belng heated to hlgh temperatures and have a fllterlng capaclty of between .5 and 1 mlcron. In a preferred embodlment, a ceramlc fllter is used, however a carbon filter or one constructed of wire mesh or spherodlzed brass would also be acceptable.
In a preferred embodlment the apparatus ls round and elongate. The flrst chamber ls annular ln shape and is bounded by the outer wall of the apparatus. Thls connects through a channel to the second chamber whlch ls cyllndrlcal ln shape and located ln the mlddle of the apparatus. The thlrd chamber ls annular ln shape and ls lnterposed between the flrst and second chambers and connects by channels to the alr outlet and the second chamber.
In a preferred embodlment the alr ls heated to a temperature of equal to or greater than 200~C. By so dolng, tests have shown that 100% of the bacteria such as baclllus stearothermophilus, penlcllllum notatum, asperglllus niger, staphylococcus, streptococcus, pasteurella spp, alcallgenes spp, moraxella, pseudomonas paucimobllis, actinomyce~
viscosus, and bacteroldes glnglvalls are kllled. Furthermore, molds such as mortlerella, wlll also be killed.

Thereafter the alr travels lnto the flrst chamber marked 4.
The flrst chamber ls bounded by the outer wall of the apparatus and the outer wall of chamber 3. The alr travels through channel-way 9 to pass lnto the second chamber.

The sterile air exiting through air outlet 6 wlll reach a desired user's temperature.
The apparatus ls also equipped wlth a screw lld 8 whlch can be removed ln order to facllltate cleanlng or replacement of the ceramlc filter 3.
