The Allentown’s N-type Pneumatic gun is a modern version of the original cement gun built by Allentown for a century.

Features & Benefits:

• Most versatile machine available for the complete range of dry-process gunite, shotcrete and refractory applications
• Ruggedly built to withstand hard, continuous use
• Renowned for its ability to feed dry or damp, coarse or fine, and dense or lightweight materials at a smooth, accurately metered rate over 500' (152m) vertically or 1,000' (305m) horizontally

This unit allows for the controlled addition of moisture to bagged material as it passes through the water ring. Pre-dampening eliminates static electricity while greatly reducing dust and rebound, providing greater visibility for the nozzleman.
