SECTION 6: COLLECTION SYSTEM

General

The Model G0548 can be operated as either a stationary or a mobile unit. There are advantages and disadvantages to both set-ups. The advan- tage of the mobile system is eliminating the cost of many ducts and fittings. On the other hand, the stationary system is more versatile and conve- nient.

The Model G0548 is designed to be a central dust collector system. Locate the dust collector in an out of the way location such as a corner or separate room. The dust collector is capable of collecting dust from up to two machines running simultaneously. Because of the large suction capacity of the Model G0548, great flexibility is possible in the planning and designing of your dust collection duct layout. Grizzly offers a com- plete line of dust collection accessories for setting up a stationary system. Additionally, Grizzly offers a guide book entitled Dust Collection Basics.

Whatever system you choose, always make sure there are no open flames or pilot lights in the same room as the dust collector. There is a risk of explosion if dust is dispersed into the air.

Material Selection

You have many choices regarding main line and branch line duct material. In most commercial workshops, the main line and branch lines are usually metal duct. Flexible hose is then used to connect each machine to the branch lines. In the case of small home shops, flexible hose may be used for both main line and branch line ducts. Plastic duct is also a popular material for home shops. Please be aware that there is a fire or explosion hazard if plastic duct material is used for dust collection without being grounded against static electrical charge build-up. This topic will be discussed later in the manual.

METAL DUCT

Metal duct comes in many varieties. Stove pipe, heating/ventilation duct and duct made especial- ly for dust collection are all options. Advantages of metal duct is its conductivity and that it does not contribute to static electrical charge build-up. However, static charges are still produced when dust particles strike other dust particles as they move through the duct. Since metal duct is a conductor, it can be grounded quite easily to dis- sipate any static electrical charges. However, metal duct is generally more expensive than plastic duct and it is not usually airtight unless specifically manufactured for dust collection. Specially manufactured metal duct, on the other hand, is quite expensive. Metal duct is also gen- erally more difficult to cut and assemble.

FLEXIBLE HOSE

Flexible rubber hose, polyethylene, plastic flex- hose and other flexible ribbed hose is generally used for short runs, small shops and at rigid duct- to-tool connections. There are many different types of flex hose on the market today. These are manufactured from materials such as poly- ethylene, PVC, cloth hose dipped in rubber and even metal, including steel and aluminum.
