CM-1500 Portable Attic Insulation Machine / Blowers
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
The CM-1500 gives impressive production rates vs 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. The additional (8.5 amp) motor is necessary to achieve 4psi. For best performance, the 12 amp motor consistently provides 4-5psi which is an excellent and capable standard for dense packing. The difference in pricing between a 8.5 and 12 amp motor is $60.
