CM4500XLS Rendering - 1 (2022)

Our classic “Big Dog” CM-4500XL series machine combines a large (132 cubic ft.) hopper, high speed production into a simple, compact machine that can do-it-all. The optional 12” x 24” oversized airlock feeder and 10 h.p. positive displacement (P.D.) blower provides the ‘punch’ to knock-out the big jobs.

Wall Spray? Bring it on!!! Our optional 10 h.p. (P.D.) Vac-Pack Recovery Systems streamline the spray process and reduce labor costs.

Big” dry hopper (91 cubic ft./20 bags stacked bags cellulose) allows operator to leave the truck for long durations assisting with duties inside the structure.

Fast” vacuum speeds (10 h.p. P.D. Vac-Pack system) fills the large capacity (26.5 cubic ft.) recycle hopper quickly…allowing vacuum operator ample time to scrub walls.

Simple” dual slide gate controls for recycle and dry in a single, compact machine provide a fast, accurate application of dry blended fibers into the wall; while conserving space inside your vehicle.

Our ‘integrated recycle technology’ precisely controls the introduction of dry and recycle fiber in a separate metering hopper. This process significantly increases speed of application and decreases moisture. These features allow the contractor to reduce labor while allowing the spray nozzle to run non-stop. The “Big Dog” CM-4500 is “THE” solution to increase profits on large, demanding jobs.
