About Performance Rates on Insulation Machines: Blowers and Vacuums

“This blower can blow 2,000 lbs of cellulose an hour!”

“Our vacuum can extract 3,000 lbs of cellulose an hour!”

What about production rate claims? What is the thinking and process behind making these claims? There are varying, wildly skewed rates that are published on the internet and claimed over-the-phone. Can they be trusted? Why or why not? What goes into establishing these rates? [Read more…]

Dealing With Static Electricity from Insulation Blower and Vacuum Hose

Dealing With Static Electricity from Insulation Blower and Vacuum Hose

Static electricity builds up in the hose in low humidity conditions and when the material (e.g., fiberglass) is dry. Whether you are blowing or vacuuming, this static electricity cannot be avoided when the conditions are right. Sometimes, this can present a very powerful jolt to the person at the end of the hose.

Yes. Anti-static hose is available. It is very expensive. a 50 foot length of 3″ anti-static hose runs $500 (as of the year 2015). 4″ diameter hose with a 50 foot length is $755 (plus shipping).

Here is an alternative that really works! You can make your own static eliminator. The illustration below shows a couple of sections of hose. Figure A is a steel hose connector that is placed within 10 feet of the end of the hose. If you place the connection any further back from the person at the end of the hose, he will still get static electricity. Loosely coil a strand of wire (Figure B) around the hose and attach the end to an iron stake that is driven into the ground (Figure C) to ground the current that builds up.

Insulation Removal Vacuum Maintenance

Insulation Removal Vacuums take more abuse than most insulation machines. They are designed to remove insulation (along with debris) in the attic and they are always in a cloud of dust. A gas engine, in these conditions, needs proper and continued maintenance.

What’s worse? Debris flying THROUGH your vacuum, or debris flying AROUND your vacuum? They are both equally bad. Dust accumulates very quickly and can starve your engine, causing it to fail.

Here are some videos that are designed to help you with your vacuum maintenance.

The ABCs of the Cool Machine Insulation Blowers & Vacuum Brand

The ABCs of the Cool Machine Insulation Blowers & Vacuum Brand

So, what sets Cool Machines apart? The Cool Machine brand has become a favorite among contractors. Dave Krendl and Andy Schulte have combined their experience and engineering skills to make innovative insulation machines. It is easy to advertise one’s equipment as “tough” and “durable.” It is quite another to actually BE tough and durable. Here is a quick run-down of how the Cool Machine Insulation blower brand is superior.

A – Airlock. The Cool Machine airlock is extruded. That produces a perfect, cylindrical shape that has no imperfections. Airlocks are typically rolled from flat steel with welded seams. The seams and non-perfect cylinder wears on the airlock seals and allows some air to bypass even new seals. The Cool approach is to have a perfect cylinder that achieves greater PSI and lets your seals last much longer.


B-Bearings. Heavy-duty, triple-sealed bearings that are re-greasable, make for durable long lasting components. These bearings are easily accessed to make for fast, simple maintenance. The advantage of the Cool Machine brand is that the augers do not spin at a high-rate of speed. Also, the beefy auger dimensions are generous and make for very durable, long-lasting machines.


C – Coatings. When Cool Machines introduced their brand to the market, they powder-coated every steel component (hopper, blower cabinet, auger system and even the hose connectors!). The powder-coating is heavy-duty and long-lasting coating. We don’t paint the machines. They are made to withstand moisture, scratches and the expected abuses industrial equipment demands.


D—Drive System. We already discussed the attention placed on the durability of the bearings. The drive-system is no different. We use agricultural-grade motors to run the agitators. The blowers are updated Ametek blowers that have nearly twice the life span of older generation centrifugal blowers. We even offer a Positive Displacement blower option that, with simple maintenance, will last twenty years. ALL of these components are modular. You can change any of the components WITHOUT having to change the entire box. The beauty of the Cool Machine brand is that these are easily interchangeable with a few simple tools.


E—Ergonomic Design. So, you want to carry a machine in a trailer or truck, but you want to pack in as much material as you can and still give the operator room to work. The Cool Machine brand has the slimmest machines on the market, without sacrificing cubic feet in the hopper. Our CM2400 handles a full bag of fiberglass. With the extension, you can put two bags of fiberglass in that machine. All the way up to our CM4500, you are able to throw 24 bags of cellulose in at a time.

That is a quick overview of the Cool Machine brand. It is easy to say your equipment is “tough.” For us, durability and ruggedness is not taken for granted. We look at every aspect of the machine and build it with durability in mind.

An Innovation Leading the Insulation Machine Industry: Scalping Augers

What makes an insulation blower stand out from the others? It is how well it breaks down the pre-packaged blown material and the conditioning process. The compressed material needs to be expanded and broken down. The scalping auger system is unlike any other in the insulation machine market. Here’s why…

Other blowing machines are designed to bat at the insulation with flailing arms.

Illustrations showing how typical arm systems create the bridging effect.

Two sets of arms, one upper set and one lower set, spin around, grabbing the material and creating chunks. If you have loaded one of these machines, the upper arms are a bit unnerving, especially if you had the arm grab the insulation wrapper or your clothing. These machines come with strict warnings to never put your hand into the hopper to clear the material. There is a very good reason for that. It doesn’t take much to get in trouble with that style of hopper.

Besides the safety risks, there is a problem with the way those arms handle the material. Instead of pushing the material toward the airlock, these arms are breaking the bales into chunks of material and allowing gravity to pull the material into the airlock. This is inefficient and time is lost, especially when the arms create a void. This is called “bridging.” That is when the material is pushed up to the top of the hopper and the material does not fall. It can’t fall. It gets compacted upwards.

Another approach is to use a carousel at the bottom of the hopper.

This carousel picks the material and spins it around the hopper which is usually cylindrical. This mechanism does not condition the material well. It will send chunks into the airlock and the sprayer will experience “baseball-shaped” material from time-to-time.

Again, this carousel is prone to bridging. It relies on gravity to push the material to the airlock.

Our approach to decompressing and conditioning the material.

The Cool Machine scalping auger action

Cool Machines has augers at the base of the hopper. There is very little risk of anyone getting caught in those augers because you would have to nearly climb into the hopper to reach the augers.

When it comes to preparing the blowing material, the augers separate the material using tabbed augers. These augers push the material toward the airlock. The material has only one direction it can go… to the airlock. At the end of the augers are scalpers which are directly above shredders. The material is force-fed into the shredders and the airlock. This is why our portable machines produce so well. More material is forced into the airlock and shredded before it enters the airlock.

The Cool Machine brand is known for its efficiency and excellent material conditioning blowers. Or trouble-free material auger system will save you time and money. See our video below on how well it handles blowing materials.
