RIX introduced its helium version of the popular MicroBoost compressor at the Divers Equipment Manufacturers Association (DEMA) show in Las Vegas in October. Divers were impressed with the small size and attractive price of this versatile compressor. Being able to compress helium as well as oxygen means that divers can make their own heliox mixtures. Also, since the compressor will take suction pressures down to atmospheric the divers can scavenge all the gas out of the supply cylinders and avoid sending them back with residual helium and oxygen.
