Air Compressors

The best method to drill an open hole in consolidated rock is to use as Down-the- Hole Hammer striking a hard tungsten tipped button bit. DTH hammers are powered by compressed air that pick and drive the heavy steel piston onto the drill bit to percussively break and pulverise the very hardest rock – the discharging air passes through the drill bit and lifts the rock debris to surface.

Special Note: Current air compressors produced commercially comply with both North Amercian & European directives on clean emissions - To achieve this engines are the latest generation common rail design and need to be maintained by approved agents of the diesel engines . It is essential to ensure this maintenance can be undertaken locally. In many locations customers are advised to purchase Air Compressor direct from local appointed agents to ensure the essential after sales service is available.

PAT will only sell compressors when local service of units will be taken care by approved agents of the diesel engines.
