How Insulation Blowing Machines Work

January 27, 2016

An insulation blowing machine will break up insulation materials which are bundled up and capture the insulation which is inside a sealed chamber situated at the bottom of the hopper of the machine. Air pressure which is created by a blower or compressor blows the insulation out from the chamber and then through the hose.

There are typically two types of insulation blowing machine, electric powered and the gasoline engine powered machines. Most professional companies that sell insulation machines make use of gas powered machines since these machines blow insulation more conveniently and quickly compared to electric powered machines. However, gas powered machines are quite expensive. It’s also important to note that smaller electric machines equipped with rotating metal do a great job in blowing fiberglass if they are in good condition. Blowing fiberglass often poses a challenge to smaller electric machines and the job can be relatively slow if the machine that you use is not appropriately designed for fiberglass or if it has been poorly repaired. The controls on blowing machinery will adjust the air pressure as well as the insulation flow rate. The operator will typically start with a medium to high air pressure and a low delivery rate 1 deposit casino If the delivery rate is too fast, the hose may clog which is something that should be avoided at all costs. If on the other hand the delivery rate is too slow, the cavity will take very long time to fill and the insulation will be packed too tightly. It can also bulge the interior or exterior paneling. You need to adjust the pressure and the delivery rate in order to fill the cavity steadily quickly without bulging the sheeting of the cavity or clogging the hose.

An excellent lubricant for insulation blowing machine hoses and blowers is graphite powder. All you need to do is mix a cup of powder with half a hopper that is full of insulation. For larger hoppers, you need to proportionately add more graphite in the mixture. Blow the mixture that you have through the blower and through the hoses and then back into the hopper. After several minutes of circulating the mixture you created, blow it into a bag for future use.

Fittings, hoses and fill tubes

Both the fittings and the hoses of insulation blowing machines are important to have effective insulation blowing; the fill tubes, connections and hoses should be as airtight as possible in order to avoid weakening the pressure needed to blow insulation. When you are filling closed building cavities, it is important to reduce the diameter of the hose from 4 inches down to about 2 inches. You can use rubber or metal as your reducer for the diameter of the hose.

Insulation can travel several feet from the end of the insulation blowing machine hose to double the section of an attic or a floor cavity. However, in more narrow cavities, insulation which is blown will not really travel much more than one foot.
