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

  • 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.
  • 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.

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.
