The Hose-type Air Gun is a heavy-duty, flexible pneumatic tool designed for high-efficiency inflation of dunnage bags in confined or hard-to-reach spaces, such as deep within shipping containers or between tightly packed cargo. It consists of a robust gun body connected to a long, durable air hose that links directly to a stationary external air compressor. This extended reach allows operators to position the inflation point precisely without moving the compressor, significantly speeding up the container loading process and reducing physical strain. Built for continuous use in demanding logistics environments, it offers a reliable, powerful, and ergonomic solution for rapid air transfer where fixed air supply is available.
