We inspect around 65 blowers a year and actually repair about 50 blowers a year. The blower sizes range from small 2" gear machines (~50 CFM) all the way up to 12" and 14" gear machines (over 7,500 CFM). But recently we were able to repair a 2231 PD blower, those are 22" gears (capable of over 11,000 CFM)! This blower presented many challenges, but that will be covered in a later post. It was neat to have in our shop for repair just because of the enormity of the blower as it stood over 6' tall and weighed about 6 tons. Right now we just wanted to share some photos of the process. The first two photos are of the repair center in general (one showing a repair on a helical screw blower) and the last six are of the 22" gear blower.

Removing the blower bearings.
Setting the impellers back in the blower.
Once the impellers are set the machine clearances will be checked.
Once the rebuilding process was finished it was time for testing!
We had to customize a test stand specifically for this blower.
We test many blowers at our facility, but this was one of the largest!
