Technical Features and Performance of the Airtec Mod. 441 Ratchet

The Airtec Mod. 441 compressed air ratchet wrench (Code 12301021) represents the high-performance solution developed by Airtec Srl for assembly, disassembly, and maintenance operations in automotive repair and industry. Thanks to the 1/2" square drive and the tightening capacity for bolts up to M12, it allows for rapid operation in engine compartments and narrow spaces.

The main operational advantage lies in the impact mechanism integrated into the ratchet head: unlike traditional pneumatic ratchets that tend to rotate abruptly when reaching the torque limit, the Model 441 absorbs the torsional reaction, ensuring complete safety for the operator's joints. Its low average air consumption (5 liters per second) and the recommended use of an 8 mm internal diameter hose allow for flexible use with any inline compressor.
