Working principle

Air ratchet wrench Using compressed air as the power source, the energy of compressed air is converted into mechanical energy through a pneumatic motor. After the compressed air enters the pneumatic motor, it pushes the vanes or pistons inside the motor to move, thus driving the rotation of the motor shaft. The motor shaft then drives the ratchet and pawl mechanism through means such as gear rotation, enabling the one - way rotation of the socket to achieve the purpose of tightening or loosening bolts and nuts.

Product features
High torque output：high torque air ratchet wrench It can provide high torque with relatively low air consumption, and can easily handle various fastening and disassembly tasks that require high torque, such as the removal of automotive chassis bolts and the assembly of large - scale mechanical equipment.
Convenient operation: Simply connect to a compressed air source and use the forward and reverse rotation buttons. There are no complicated operating steps, so even inexperienced users can quickly get started.
Three-eighths of an inch air ratchet The square drive head is made of ultra - high alloy steel, offering excellent impact resistance and wear resistance. It provides a clean working environment. There is an air flow control knob. The air inlet is equipped with a screen filter to prevent dirt from entering and damaging the tool. The trigger features a track - type design, making it more convenient to use.
Long service life: RP7408 High - strength materials and precision manufacturing processes are adopted, and the internal components have good wear resistance.
The socket retainer enables quick and easy socket replacement. The rotor, eccentric shaft, and anvil all undergo heat treatment by German Ipsen, enhancing their durability. The high - quality alloy steel anvil, rotor, and eccentric shaft can pass the 1 - meter drop test without air leakage.

High safety level: It usually comes with an overload protection device. When the torque reaches the set value, the wrench will automatically slip to avoid bolt damage or workpiece deformation caused by over - tightening. In addition, air ratchet wrenches do not generate electric sparks during operation, making them suitable for use in dangerous environments such as those with flammable and explosive substances

Wide range of applications: It can be used in multiple fields such as automotive repair, machinery manufacturing, and construction. It is suitable for the tightening and removal of various bolts and nuts. Whether in factory workshops, construction sites, or outdoor operations, it can play an important role.
