How Loud is the CoolVac37 Insulation Vacuum?
Cool Machines CoolVac37 has a powerful 37 horsepower Briggs/Stratton Vanguard engine. It powers a belt-driven fan blade measuring 24″ in diameter by 4″ thick. The blade is 1/4″ thick AR500 steel. With these physics, you would expect this hog to be extremely noisy?
We measured the decibels of a smaller 27 horsepower vacuum (by another manufacturer). That vacuum measured as loud as a semi-truck when standing next to it. That is to be expected! Fans create alot of noise… coupled with engines of that size.
We visited TempBlocker in Wilmington, North Carolina to see the vacuum in action. The vacuum performed as expected. Two people were in the attic extracting at the same time. This vacuum had so much power that they never noticed a lag in performance. One benefit was having a vacuum of this magnitude that would not bother the neighbors.
CoolMachine’s vacuums are perfect for the insulator who wants to minimize noise volumes on the job site. Watch the video below and you will see, for yourself, the noise measurement of this vacuum… standing right next to it! The results are amazing!
