Viair 80305 Dual 485C VMS Stealth Black Onboard Air Compressor System with Cradle Bracket

The Viair 80305 is a high-performance dual 485C VMS (Vehicle Mounted System) onboard air compressor kit in Stealth Black finish, complete with a cradle bracket for a clean, integrated installation. Engineered for demanding applications, this system delivers maximum airflow and fast tire fill capability backed by exceptional durability.

At the heart of this system are two 485C 12-volt permanent magnetic motor compressors — rated for 100% duty cycle at 200 PSI, making them among the only compressors available with this rating. With a combined CFM of 3.92 @ 0 PSI and a maximum working pressure of 200 PSI, this setup excels at tire pressure management, air suspension systems, air horns, air lockers, air bags, and general compressed air tasks.

The included cradle bracket creates a modular, all-in-one mounting solution that integrates both compressors and system components onto a single platform. The bracket features multiple threaded hole positions for mounting flexibility and is electroplated for corrosion protection. Each compressor carries an IP67 ingress protection rating, making the system fully waterproof and dustproof.
