Dry dust collectors and humidity don’t react well together. Baghouses and cartridge collectors operate by having dirty (dusty) air enter the housing. Multiple filters (bags or cartridges) are located in the housing. The air travels through the filter and then exits the dust collector. The filters are a mesh of fibers that allow air to travel through small holes, while dust is too large to pass. The dust builds up a layer (dust cake), further limiting the subsequent dust’s ability to pass through while allowing the air to pass. From time to time the dust collector will clean the filters by shaking them or using compressed air to expand them. This causes the outer layer of the dust cake to fall off.
