1" Heavy Duty Air Impact Driver

1″ Heavy-Duty Composite Air Impact Wrench – Industrial-Grade Torque Performance

The GW-45SL 1″ Heavy-Duty Composite Air Impact Wrench is engineered for the toughest fastening and loosening tasks across heavy-duty professional environments. Built for durability and peak torque delivery, this pneumatic impact wrench is ideal for heavy vehicle service, industrial assembly, heavy machinery maintenance, and other demanding applications.

As part of the Brüder’s POWER FULL / THE POWER FULL AIR series, the GW-45SL offers maximum power and control where performance cannot be compromised.

Professional-Level Torque and Performance

At its core, the GW-45SL features a Super Hammer (twin hammer) impact mechanism, providing balanced, powerful strikes that translate into high rotational force and efficient fastening capability. This advanced hammer design ensures steady, dependable torque delivery even under intensive use conditions.

With a maximum torque output of 2000 ft·lb (2,711 Nm), this air impact wrench is engineered to handle large fasteners and heavy bolting jobs with ease. Whether you’re working on truck wheel hubs, heavy equipment assemblies, or industrial frame bolting, the GW-45SL’s torque delivery sets it apart in applications demanding extra muscle.

Rugged Construction and Functional Design

Designed for professional workshops and industrial environments, the GW-45SL combines a robust composite body with an aluminum hammer case, resulting in a tool that is strong yet lighter than all-metal alternatives. This balanced construction improves operator comfort while maintaining structural integrity in heavy use.

Key specifications include:

• Shank: Extended
• Square Drive Size: 1″ (25 mm) – standard for large vehicle and industrial fasteners.
• Bolt Capacity: Up to 45 mm fasteners.
• Maximum Torque: 2000 ft·lb (2,711 Nm).
• Net Weight: Approx. 10.30 kg – engineered for balanced handling despite high torque output.
• Overall Length: Approx. 550 mm – compact profile for access to crowded workspaces.
• Air Consumption: ~1.41 m³/min for strong performance with standard shop compressors.
• Air Inlet: 1/2″ connection – compatible with common pneumatic systems.
• Operating Pressure: 115 psi (approx. 8 bar).
• Sound Level: ~95 dBA.
• Vibration: ~5.5 m/s².

Ergonomic enhancements, such as the streamlined D-handle and positive action trigger, improve operator comfort and control, especially during extended usage. The lever-type forward/reverse switch allows quick direction changes, and a three-position power regulator provides adjustable tightening control for different fastening needs.

Versatile Heavy-Duty Applications

The GW-45SL air impact wrench is tailored for environments that demand consistent high torque and long-term reliability, including:

• Truck, bus, and heavy vehicle maintenance – efficient removal and installation of large wheel nuts and structural fasteners.
• Industrial assembly lines – secure bolting for frames, machinery, and structural components.
• Construction and fabrication projects – rapid fastening of structural hardware.
• Heavy machinery service – support for engines, drivetrains, and mechanical assemblies.
• Shipyards and petrochemical plants – environments where high torque tools are essential.
