Fabric Filters (or Bag Filters) are normally operated through the use of multiple bags mounted in a BAG HOUSE. A typical bag house is shown below.

• Capable of efficient collection down to < 0.5µm diameter.
• The fabric filter works on the principle of trapping dust on one side of the fabric.
• The pore size of the filter is about 100µm.

Two mechanisms allow collection of smaller particles, as described on the following pages.
