About Omega Air Compressors
Omega built its reputation on bringing tank-filling capability to airgunners at prices well under traditional dive-shop compressors. The Air Charger remains the current flagship: water cooled, rated for continuous running, and content to fill large carbon fiber tanks all afternoon. The discontinued Super Charger and Turbo Charger established the platform, and the Trail Charger brought a water-cooled four-stage design to the portable class. Airguns of Arizona handles import and after-sale service in the US, which keeps these machines supported in a category where support is rare.
