Pneumatic air trigger BK30 BK20 BK30 gas trigger 
 Air Trigger (also known as pneumatic wrenches, air trigger, pneumatic wrench, auto warranty industry, commonly known as air guns) is an efficient tool for bolt and nut assembly and disassembly, light weight, small gas consumption, torque, widely used in petrochemical, transportation, construction, electricity, railways, bridges, mining, metallurgy, shipbuilding, automobiles, machinery manufacturing and maintenance and other industries. 
 Air trigger is a compressed air power source of high-speed impact type hand tools, from gas distribution department, hair dryer Department, Ministry of the impact of three parts, the engine between the rotor and the impactor deceleration without directly splined connection, the rotor impact energy into rotational kinetic energy to achieve rapid tightening or removing the nut. The machine has a security proof, torque, light weight, small size, high efficiency, simple structure, easy maintenance and a series of features. Fluctuations in coal mine air pressure to meet the case of large output and stable speed requirements, can be used for U type steel support bracket nut and bolt tightening and removal of the stirring resin bolt nut assembly and disassembly of other mechanical and electrical equipment, can improve U bolt bracket steel bracket and performance, supporting quality assurance.
