Technical Features and Performance of the Airtec Mod. 357 Pneumatic Impact Wrench
The Airtec Mod. 357 impact wrench represents the pinnacle of pneumatic technology for tire repairers, industrial vehicle workshops, agricultural machinery, and heavy-duty carpentry. Designed to combine the maneuverability of a 3.5 kg tool with the performance needed for working on fasteners up to 32 mm (M32), it offers ideal balance to reduce operator fatigue during prolonged work sessions.
Power adjustment is done directly via the multifunction trigger, allowing you to select the desired tightening level without taking your hand off the handle.
Technological Insight: How the MECHONEER® Batting System Works
The patented MECHONEER® mechanism developed by Airtec is a hybrid impulse system that combines the Twin Hammer and Pin-less construction principles, reducing the number of moving components subject to wear.
The Mechanics of the Hybrid Mechanism:
- Twin Hammer Concept: The drive shaft (anvil) is driven simultaneously by a double hammer for a balanced, symmetrical and very high energy impact.
- Pin-less concept: the blades are guided by the cage, which is dragged directly by the rotor stem without the use of intermediate pins subject to breakage.
- Concentricity and Perfect Alignment: A centering pin connects the rear of the shaft to the rear of the rotor, ensuring perfect alignment between the rotor, cover, and cylinder. This eliminates misalignment, eliminates vibration, and prevents internal engine air leaks that would otherwise cause power losses.
- Leak-Proof Sealed Cover: The rear cover is sealed with the cage, keeping the lubricating grease inside the hammers and preventing premature wear.
- Through-Bolt Assembly: The engine structure is held in place by through-bolts that prevent the components from moving over time.
