A foundry in Minnesota needed a dust collector but had a location issue. There was just no room to set up the dust collector next to the building! After exploring the options, we were able to resolve the problem with a custom structure fabrication to install the dust collector on the roof. The customer purchased an ACT 3-24 dust collection system with a 30 HP fan, to operate at 10,000 cfm. This custom system is set up so that the material discharges through an air lock and a pipe that drops through the roof into the building. This way the maintenance personnel can dispose of the dust without going up on the roof. Needless to say, this is more safe for the employees and saves a lot of time.
