Because these Extreame Duty Units are for the longevity and reliability this is done. By removing the air output silencer and putting it on the intake the units can be be used as a high pressure blower instead.I uninstalled these myself with a forklift from the factory that they were installed in. I also have the control boxes for the units as well. They will be for sale seperately.
