Like the pulse-jet system, the Tube-Type Shaker dust collector is sometimes referred to as a “baghouse”. The Tube-Type Shaker System has been around for a long time, over 50 years according to one source, but it may be older than that. The basic design includes a multitude of cloth or felt tubes that are closed at the top and clamped to a tube sheet thimble at the bottom. Air filters from the bottom up and the inside out. The bag’s top includes a loop or strap which is attached to a shaker rack. Dust is automatically shaken free, after the fan is shut down, and drops into a hopper or drum(s).
This system is particularly well suited to fibrous or other dust that can be shaken clean off-line. Production wood-working is the primary market for this system, although it works well for grinding, aluminum sawing, and other applications where relatively coarse or fibrous dust is produced.
