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.

Features & Benefits:

• Produces proper, in-place shotcrete
• Reduces wear on gun components

For use with packaged, pre-blended materials for shotcrete and
refractory applications.

Features & Benefits:

• Provides the opportunity to add a controlled amount of moisture to the bagged material as it is transported and fed into the gun.
• The addition of moisture, as much as 60 percent of the total water required, and the mixing action of the auger starts the hydration process long before the material reaches the nozzle.
• The controlled design or prebagged mixes ensure the amount of water added at the nozzle, in the split second that the material passes through the water ring,
• produces proper, in-place shotcrete.

The Putzmeister Piccola is built to the Swiss design with a vane air motor (250–600 cfm), flat hopper with bag breaker and screen, and 11/2" (38mm) outlet diameter as standard. It is a recommended machine for dry-process shotcrete in Refractory and Civil applications. Versatile and robust, this machine requires little maintenance and is easy to operate.

Features & Benefits:

• Variable speed electric motor, diesel engine, or no power (rig mounted)
• Rotor options including 12 round-half, 12 round-full, 9 round-full, pie-half and pie-full
• Slanted hopper with screen
• Forklift skid or foam-filled rubber tire mounting
• Dust suppression system
• Built to the Swiss design with a vane air motor (250-600 cfm)

Ease of operation and maintenance makes this unit a popular choice. It’s designed for high-volume sand/cement gunning work or refractory gunning. Ideal for use with the N-TYPE Pneumatic Gun, it will also feed any Putzmeister rotary gun.

Features & Benefits:

• Designed for high-volume sand/cement gunning work or refractory gunning.
• Ideal for use with the N-2 gun, but will also feed any Allentown rotary gun.
• Tandem trailer-mounted unit.
• Mixes and delivers 8 to 10 tons/hr (7-9 tonnes/hr).
