Who We Are

Airtec International


We have manufactured and developed the Master 35® Petrol/Gas Impact Wrench since its conception in 1975.

We have manufactured and developed the Master 35® Petrol/Gas Impact Wrench since its conception in 1975. The Master 35 impact wrench has been continuously improved on to meet the demands of the Railway Industry to remove and fit Screwed Fasteners safely and quickly without the need for a separate power source.

Design changes have been made to allow for practical use, ease of repair, improved productivity through fast operation, reducing vibration exposure and reducing emission levels by using a modern low emission engine.

It is used by every major Railway Authority in Europe, North America, Australasia and in many Asian countries for loosening/tightening all sizes of screwed fasteners.

To complement our high-quality Impact Wrench, we manufacture all types of Accessories for use with Impact Wrenches and Railway Track Screwing Machines – Tool Carrier, Metal Carrying Box, Auger Bits, Impact Sockets and special products e.g. No Go Gauge and Lase Align Unit.

The Master 35® Impact Wrench is now used by other Industries where it is difficult or expensive to provide a separate power source.

We continue to work on new projects and product improvements to provide our customers with the best products available which protect operators and the environment.
