DIMO Corp. provides support and service for military aviation air separation systems. This product is the cutting edge air separation technology for aircraft application. The On-Board Oxygen Generating Systems (OBOGS) simplifies logistics for the military while saving millions of dollars annually.


OBOGS eliminates the need for liquid oxygen (LOX) by using the readily available bleed air from the aircraft’s engine. The bleed air is separated into its elements through molecular sieve technology to concentrate an unlimited supply of breathing oxygen. The oxygen is then monitored for purity and regulated before it is delivered to the pilot.

This system reduces the dependence for heavy, bulky oxygen bottles that add more stress and weight to the aircraft, as well as eliminates the risks associated with the handling and use of LOX. Most importantly, the OBOGS operational costs are significantly lower than outdated LOX systems.
