Air injectors for self drilling soil, soil nails, rods and anchorages

Ideal for micropiles and poles.

The DE/AR 80 is a pneumatic injector with double acting piston.

The high reliability and ease of use, allow to optimize site costs with the use of a single compressor for the drilling and injection phases.

The performances vary according to the available air as shown in the table.

Suitable for wall injections and for drilling and injections in general.
