About Coltri
Coltri is an Italian breathing-air compressor maker whose MCH-6 portable has long served double duty in the airgun world as the buy-once tank-filling solution. It is a true dive-grade machine, EN12021 certified for breathing air, and the pump many owners recognize inside other badges: the Daystate T2 is built around a Coltri-derived unit minus Coltri's own filter stack. Nuvair imports, tests, and configures every unit before shipping, and offers the newer, lighter Icon line as the MCH-6's successor.
