Insulation Machine Comparison Chart

Monsoon Machines, Capitol Machines, Meyers Machines, Unisul Machines, Krendl Machines, Ark-seal Machines, ACCU1 Machines, Intec Force Machines, Insulmaxx Machines, Heat Seal Machines, Cool Machines… whew!


Choosing an insulation blowing machine is an important decision that requires some sort of way to compare them that a person can understand. What we have done is developed a simple chart comparing some of the common insulation machines on the market. We decided upon a totally objective system. We take the pounds per hour of fiberglass and cellulose and divide that into the cost of the machine. All machines featured are industry leaders in fiber output and quality built machines. Since a contractor gets paid by output, we thought this chart would be useful to contractors in calculating the actual cost of available lightweight/portable machines.

Our equipment is a ‘compact’ low power requirement design utilizing a proprietary ‘scalping’ auger design to achieve the performance of the bigger machines. This efficient design allows us to use smaller drive motors (less power, less cost, lower replacement cost), without compromising production rates and coverage.

All CM-1500 and larger insulation machines will have the following upgrades:

  • Built-in, liquid filled pressure gauge to calibrate machine pressure as airlock seals wear or become damaged. Many dense-packing applications require a minimum 3.2 p.s.i. to achieve the required densities in the wall.
  • L.E.D. indicator lights on input and output cords, for quick electrical power diagnostics of main control panel and individual motors
  • Panel mounted manual thermal overload protection for all electrical components. This allows quick, safe, diagnostics and re-setting of breakers without opening panel box and allowing fiber contamination into the electrical components.

Additionally, we have redesigned the CM-1500 (tall) hopper to eliminate nuisance ‘bridging’. The CM-2400 and CM-3000/3500 models have increased hopper length (6″ inches) to provide a greater holding capacity for fiber.
