The Coltri MCH-6 (also marketed as the Coltri Icon in some markets) is a portable, 4-stage breathing-air compressor delivering a 4.2 SCFM (100 L/min) charging rate at 4,800 PSI (330 bar), aimed at dive instructors, small dive shops, and paintball facilities that need field-filling without a stationary plant. The compressor block is air-cooled, splash-lubricated with synthetic Coltri oil, and is offered with either a Honda GX160 gasoline engine for off-grid portability or a 230 V single-phase electric motor (~2.2 kW). Standard purification is a 3-stage filter stack (oil-and-water separator, activated charcoal, molecular sieve) producing CGA G-7.1 Grade E / EN 12021 breathing air. Best for portable dive-shop work and instructor fleets where MCH-13 stationary throughput is overkill.
