Do I Need More Than One Blower?

double-blowerCool Machines offers multiple blowers in their machines. Multiple blowers are placed into the machines to create higher velocity. Do you really need more than one blower? This article attempts to explain this frequently asked question…

What multiple blowers will NOT do

  • More than one blower on a machine does not mean you will have two outputs. Multiple blowers are joined inside the machine.
  • Multiple blowers do not increase production. See the article on airlocks for an explanation on how production is increased.

What multiple blowers ARE designed to do

Wall Spray

Wall spray is stabilized by introducing glue or water to the material. When recycled, the material is heavier and requires more velocity to push through the hose.

Internal Wetting System

Cellulose is very dusty. An internal wetting system adds a small amount of water as the material enters the hose. Again, the damp material is heavier and requires greater velocity to push through the hose.

Add Additional Length to Hose

Production rates are based on 100 feet of hose raised to the elevation of 12 feet. 99% of insulation situations require only 150’ of hose, especially with the portable units. There are times, especially in commercial applications where you will want to use longer hose to reach. The longer the hose, the more velocity is required. To maintain the velocity, additional blowers are required. Here are some suggestions:

  • If you have a CM1500 and want to use more than 200’ of hose, then a double blower is required. You will need two 20 amp circuits to operate a double blower system.
  • The CM2400 is already outfitted with two blowers. You can outfit a CM2400 to have up to four blowers. In that case, where you want that kind of velocity, strongly consider our 5 horse power positive displacement blower. You will need 50 amp service to operate a CM2400 that has more than 2 blowers.
