title: "Baghouse"
description: "A baghouse is the structural enclosure that houses the bags, cages, cleaning system, tubesheet, plenums and hoppers of a fabric-filter dust collector. The word is used in both broad (\"the plant has a 12-compartment baghouse\") and narrow (\"a baghouse is the housing, the fabric filter is the system\") senses; in everyday industry practice the two terms overlap."

A **baghouse** is the structural enclosure that houses the bags, cages, cleaning system, [tubesheet](/glossary/tubesheet), [plenums](/glossary/plenum-clean-side-dirty-side) and hoppers of a [fabric-filter](/glossary/fabric-filter) dust collector. The word is used in both broad ("the plant has a 12-compartment baghouse") and narrow ("a baghouse is the housing, the fabric filter is the system") senses; in everyday industry practice the two terms overlap.

## Compartmented design

Large industrial baghouses are subdivided into several compartments — each with its own gas-flow damper — so that one compartment can be isolated for offline cleaning or bag replacement while the rest stay online. The standard [pulse-jet](/glossary/pulse-jet-baghouse) compartment count for utility duty is 8–16; cement and [WtE](/glossary/waste-to-energy) baghouses may run 20+.

## Why sonic horns help

Sonic horns mounted at compartment level address fouling that the primary cleaning system (pulse-jet, reverse-air or shaker) cannot reach:

- Bag-row dead zones at the back of the compartment
- [Tubesheet](/glossary/tubesheet) area dust deposits
- Hopper bridging below the bags
- Inlet-plenum dust dropout
