CM3500 Insulation Blower

Shown with optional hopper extension

The CM3500 is our workhorse that incorporates a dual hopper. The narrow profile helps save time on the job. Easy-to-load and maintain.

The CM3500 is a perfect solution for larger commercial applications where you need to fill large attics.

The separated hopper allows you to use this as an attic blowing machine as well as a wall spray machine. You are able to separate damp material from dry material. The metering technology allows the damp material to recycle evenly for wall spray jobs.

The positive displacement blower will give you decades of trouble-free operation. The generous hopper will hold 24 cubic feet of material. Our hopper extension will nearly double the amount (46 cubic feet).

The augers are slow speed to provide safety and long component life.

The turbo-shredder conditions the material so that coverage and production are maximized.

Two stainless steel slide gates provide you with extreme accuracy in adjusting the amount of material you blow from the dry and recycle hoppers.


Options that are available with this unit are:

  • Upgrade from 5 hp Positive Displacement blower to 10 hp
  • Extended hopper (shown in picture).
  • Vacuum Hood. An option that allows you to use a standard insulation removal vacuum to recycle material
  • VacPac Recycler. Our fully-integrated vacuum recycling option.

You can power this unit with either on-site electrical (240 volt 30 amp) or a 17.5kw generator.
