Annular Port Source
8500 - Teledyne Marine Bolt
The principal feature of the revolutionary Annular Port Source design is the annulus within which the air chamber and shuttle valve are housed.
The air chamber and shuttle valve, in turn, surround a hollow passage through which air supply hoses and electrical control cables are routed. Peak output is optimized by an increased surface area of the toroidal-shaped bubble compared to the spherically shaped bubble generated by a conventional 4-port air gun.
