Why contractors should choose the CM-3500?

Recyclable moisture controlling:

Moisture is always a problem while maintaining insulation wall spray system. CM-300 keeps this to a minimum. In fact, the Coll Machine brand will reduce water needs up to 50%.

Introducing Vac-Pack technology for low maintenance and better efficiency:

gallery-300Most of the machines running on current industry standard follows two backdated methods for recovery and use of recycle fiber. To recycle fiber back to the dusty truck trailer gas powered centrifugal is used which comes with high maintenance cost. It is also time consuming. It also slows down the production rate with pressurized recycle hopper while inherent of fiber flow and air surging problems occurred. Setting up and hauling recycle with buckets back to a manually loaded machine inside of multiple level structures is both time consuming and a dangerous liability risk when handling heavy equipment.

CM-3500 provides an efficient and fast solution. Our Vac Pack technology offers a low maintenance positive pressure vacuum system with no slow down in production by discharging neutral pressure hopper inside with no resulting air surges or dust. It increases endurance of the system with air bypass technology with exclusive air separator which keeps the distance of recycle fiber form contact with the blower. The filter system needs services once a day to insure high efficiency in most cases at the end of the day. CM-3500 also offers a fast, smooth reliable spraying system to meet-up minimizing setup time and maximizing production.
