There are a number of options when it comes to metal duct, but metal duct that is specially manu- factured for dust collection is the best choice. When selecting your metal duct, choose high quality metal duct with smooth welded internal seams that will minimize airflow resistance. This type of duct usually connects to other ducts or elbows with a simple, self-sealing clamp, is very quick and easy to assemble, and can be readily dismantled and re-installed. This is espe- cially important if you ever need to change things around in your shop or add more tools.

Avoid inferior metal duct that requires you to cut it to length and snap it together. This type of duct is time consuming to install because it requires you to seal all the seams with silicone and screw the components on the ends with sheet metal screws. Another disadvantage is the rough internal seams and crimped ends that unavoidably increase static pressure loss.

Flexible Duct

Flexible 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 polyethylene, PVC, cloth hose dipped in rubber, and even metal, including steel and aluminum.

The superior choice for flexible ducting is metal flex hose that is designed to be flexible and as smooth as possible to reduce static pressure loss See Page 29.

Figure 30. Example of flexible metal duct.

There are also many kinds of pure plastic flexible hose, such as non-perforated drainage type hose and dryer vent hose. Drainage type hose, while being economical, does not quite have the flex- ibility required for dust collection. The inside of the duct is also deeply corrugated and can increase the static pressure loss by as much as 50% over smooth wall duct. Dryer vent hose offers greater flexibility, but is non-resistant to abrasion and tends to collapse in a negative pressure system. We DO NOT recommend using dryer vent hose in your dust collection system.

If using flex-hose, choose one of the many types designed specifically for the movement of solid particles, i.e. dust, grains and plastics. However, the cost of specifically designed flexible duct can vary greatly. Grizzly offers polyethylene hose, which is well suited for the removal of particulate matter, especially sawdust, since it is durable and completely flexible. Polyethylene is also very eco- nomical and available in a wide variety of diam- eters and lengths for most applications.

Plastic Duct

The popularity of plastic duct is due to the fact that it is economical and readily available. It is also simple to assemble and easily sealed against air loss. The primary disadvantage of plastic duct for dust collection is the inherent danger of static electrical build-up.

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.
