CM 1500 Portable Attic Blowers

We are very excited to own our Cool Machine 1500 Model here in Alaska. To date, two different contractors have used this machine and each one raved about it. Im not used to folks in the insulation industry getting so excited about doing such hard work! I love it! The cool machine is powerful, easy to use and operate and makes a tough job much easier. One of my favorite parts though, is working with Barry, he has the best customer service I have seen in years. Barry is responsive and knowledgeable. The customer can tell that he cares about what he does and it is not just a business transaction. That means a lot to me in todays market. We have recommended him and the Cool Machine to three other contractors already. I like the sturdy design of the unit and when people talk about it they don’t even notice that they say, That is a really cool machine! Margaret Subers of Alaska Building Science Network

Barry, We purchased a CM1500 in mid July of 2011. It performs just like you said it would. It is a solid hard working addition to our bottom line. We will definitely purchase from your company on our future needs and upgrades. Thanks, Robin Hudson VP Weathers Refrigeration

Barry, Just wanted to drop you this email to thank you for all your help. The CM 1500 that you said would do the best job for what I needed at this time is working fantastic. A well built machine, I’m glad I went with this one. The help that I needed after the sale is what I really like, not to many business people do that, great Job! I will recommend you to others. Thanks again, John Von Eper, Owner, Wylie Insulation, Wylie,Tx

portableThe CM-1500 gives impressive production rates versus cost in the insulation machine industry. If you want mobility with low power requirements and high production, then this is for you. In-fact, it will take you closer to higher production of large machine capabilities. Insulation was never been so easy but this gives you freedom to cover your quick production needs.

The many options (blowers, input power, wheel package), offer choices to the small contractor that require versatility, production, and low maintenance in a high endurance machine. (scalping augers /shredder) A Great Choice for the Weatherization Contractor.

Frequently Asked Questions

  • Is the CM1500 able to insulate 3 homes a week (2,500 square feet)? Yes. This machine will provide consistent, reliable service at that level. If you insulate apartments, commercial buildings and large areas consistently, this machine will work, but consider a CM2400.
  • How does the CM1500 perform with dense packing walls? This is a great machine for dense packing. For best performance, the 12 amp motor consistently provides 4-5psi which is an excellent and capable machine for dense packing.
