Determining Main Line Duct Size

The general rule of thumb for a main line duct is that the velocity of the airflow must not fall below 3500 FPM.

For small/medium sized shops, using the inlet size of the dust collector as the main line duct size will usually keep the air velocity above 3500 FPM and, depending on your system, will allow you to keep multiple branches open at one time.

Mark your drawing as in Figure 38, but using the inlet size for your dust collector as the main line.

Determining Branch Line Duct Size

The general rule of thumb for a branch line duct is that the velocity of the airflow must not fall below 4000 FPM.

For small/medium sized shops, using the dust port size from the machine as the branch line duct size will achieve the correct velocity in most appli- cations. However, if the dust port on the machine is smaller than 4", make the branch line 4" and neck the line down right before the dust port.

Note: Systems with powerful dust collectors work better if multiple blast gates are left open. This also allows you to run two machines at once. Experiment with different combinations of blast gates open/closed to find the best results for your system.

Write your determined branch line sizes on your drawing, as shown in Figure 39.

Here are some frequently asked questions when determining branch line sizes:

How do I figure which size of branch line to use if the machine has two dust ports?

Simply add the total CFM given for each size from Figure 35 and refer that CFM number to Figure 40. Then, split the branch line just before the dust ports with matching duct sizes.

What if two machines share the same branch line? You have two options:

1.If both machines will be running at the same time, add the total CFM given for each size from Figure 35 and match the branch line given in

Figure 40.

2.If both the machines will never be run at the same time, reference the machine with biggest dust port to Figure 40 and add blast gates after the Y-branch to open/close the line to each machine.

Model G0562Z/ZP, G1030Z2/Z2P (Mfg. 11/11+)

G1030Z2 specifications

The Grizzly G1030Z2 and G0562Z are two remarkable dust collection systems designed for woodworkers and craftsmen who prioritize maintaining a clean and efficient working environment. These machines are pivotal in minimizing airborne dust and debris, contributing not only to a tidier workspace but also to improved health and safety standards.

The Grizzly G1030Z2 is a powerful 3HP dust collector with a 2-stage cyclone system. Its two-stage design improves efficiency by separating larger particles from fine dust before reaching the filter bag. This not only prolongs the life of the filter but also enhances the overall suction power of the unit. With an airflow capacity of 1,200 CFM, the G1030Z2 is capable of handling multiple machines simultaneously, making it an ideal choice for serious woodworkers or small to medium-sized shops. It also features a large, 30-gallon collection bag, allowing for extended use before needing to be emptied.

On the other hand, the Grizzly G0562Z is a versatile and compact option that is perfect for small shops with limited space. This dust collector, also featuring a 2HP motor, offers a combination of powerful suction and a compact footprint. The 1,100 CFM airflow effectively captures dust from stationary machines. The G0562Z includes a convenient 5-micron felt filter bag that ensures even the finest particles are captured, offering an environmentally friendly solution to dust management. The design of this model includes wheeled casters for easier mobility around the workshop, providing convenience and flexibility for woodworkers performing various tasks.

Both models feature sturdy construction and easy-to-use systems for changing collection bags, ensuring minimal downtime in your workflow. Moreover, they boast noise-reducing technology, which is essential in settings where multiple machines operate simultaneously.

Overall, the Grizzly G1030Z2 and G0562Z embody the balance of innovation, efficiency, and functionality. They are engineered with the modern woodworker in mind, integrating advanced technologies that promote not only productivity but also safety, making them valuable assets in any woodworking shop. Through their high performance and reliability, these dust collection systems significantly contribute to a healthier workplace atmosphere.
