3.Directional changes should be kept to a mini- mum. The more directional change fittings you use directly increases the overall resis- tance to airflow.

4.Gradual directional changes are more effi- cient than sudden directional changes (i.e. use the largest corner radius possible when changing hose or pipe direction).

5.Each individual branch line should have a blast gate immediately after the branch to control suction from one machine to another.

6.The simpler the system, the more efficient and less costly it will be.

Step 4. Determine Required CFM of Each Machine

Since each machine produces a different amount of sawdust, the requirements for the minimum amount of CFM to move that sawdust is unique to the machine (for example, a planer produces more sawdust than a table saw). Knowing this required CFM is important to gauging which size of duct to use.

Figure 16 will give you a close estimation of the airflow your machine requires. Keep in mind that machines that generate the most sawdust should be placed closest to the dust collector. If the machine has multiple dust ports, the total CFM required is the sum of all ports.

Machine	Approximate
Dust Port Size	Required CFM
2"	98
2.5"	150
3"	220
4"	395
5"	614
6"	884
7"	1203
8"	1570
9"	1990
10"	2456

G5954 5HP Dust Collector

If your machine doesn't have a built in dust port, use Figure 17 to determine which size of dust port to install on your machine.

Machine	Average Dust Port Size
Table Saw		4"
Miter/Radial-Arm Saw		2"
Jointer (6" and smaller)		4"
Jointer (8"-12")		5"
Thickness Planer (13" and smaller)		4"
Thickness Planer (14"-20")		6"
Shaper		4"
Router (mounted to table)		2"
Bandsaw		4"
Lathe		4"
Disc Sander (12" and smaller)		2"
Disc Sander (13-18")		4"
Belt Sander (6" and smaller)		2"
Belt Sander (7"-9")		3"
Edge Sander (6" x 80" and smaller)		4"
Edge Sander (6" x 80" and larger)		5"
Drum Sander (24" and smaller)		2 x 4"
Drum Sander (24" and larger)		4 x 4"
Widebelt Sander (18" and smaller)		5"
Widebelt Sander (24"–37" single head) ..		2 x 6"

Widebelt Sander (24"–51" double head).5 x 4"
