Specification

What is Onpin OP-914D2?

The Onpin OP-914D2 air impact wrench is a heavy-duty pneumatic tool designed for tightening and loosening large bolts and nuts. Powered by compressed air, the device converts energy into high-rotational impact torque via an internal hammering mechanism. It serves as a high-performance solution for demanding industrial assembly lines and heavy machinery maintenance.

Key Features of Onpin OP-914D2

1. Side exhaust design redirects discharged air away from the working area, maintaining high safety standards and clean operational visibility.
2. Outside trigger mechanism provides ergonomic and convenient throttle operation, even when operating with heavy industrial safety gloves.
3. 1/2" driver anvil length provides a robust connection drive, ensuring reliable torque transfer and minimal wear on impact sockets.
4. High output capability delivering a maximum torque of 2500–2900 Nm at a standard operating air pressure of 90 psi (6.2 bar).
5. Efficient pneumatic motor producing 2800 rpm free speed with an air consumption rate of 452 l/min (16 cfm), balancing high performance with air system efficiency.
