There are quite a number of options when it comes to metal duct, but metal duct that is spe- cially manufactured for dust collection is the best choice. When selecting your metal duct, choose high quality metal duct with smooth welded inter- nal 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. See the Accessories section on Page 36 for examples.

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.

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.

G0638, G0637 specifications

The Grizzly G0637 and G0638 are two robust woodworking machines designed to cater to both amateur woodworkers and seasoned professionals. These models stand out for their precision, durability, and versatility, making them ideal for various woodworking applications.

One of the main features of the Grizzly G0637 is its powerful 3 HP motor, which provides ample power for cutting through different types of wood with ease. This capability makes it suitable for heavy-duty tasks, including jointing and planing thick lumber. On the other hand, the G0638 model boasts a twin-knife cutterhead for enhanced efficiency, providing smooth finishes and improved stock removal rates. This feature is particularly useful for woodworkers who require high-quality outputs in less time.

When it comes to technology, both models incorporate advanced engineering principles to ensure operational stability. The Grizzly G0637 features a precision-ground cast-iron table designed for flatness, contributing to accurate results. This table is also fitted with an integrated dust collection system, which helps maintain a clean workspace by minimizing sawdust accumulation during operations. The G0638 model enhances this design with a spiral cutterhead, featuring multiple carbide inserts that provide a cleaner cut and longer life than traditional blades.

Another notable characteristic of both models is their user-friendly design. The height adjustment knobs are conveniently placed for easy access, allowing users to quickly adjust the cutting height without disrupting workflow. Additionally, both machines are equipped with oversized handwheels that enable fine adjustments, ensuring that every cut meets precise specifications.

Safety is another important aspect of the Grizzly G0637 and G0638 models. Each machine includes features such as anti-kickback pawls and blade guards, which promote safe operation while handling various stock types. The solid construction of these machines also minimizes vibrations, further enhancing stability and safety during use.

In conclusion, the Grizzly G0637 and G0638 represent the pinnacle of woodworking machinery, combining power, precision, and user-friendly features. Their innovative technologies and solid construction make them a valuable addition to any workshop, allowing woodworkers to achieve exceptional results in their projects. Whether you're jointing edges or planing surfaces, these machines are designed to enhance performance and elevate craftsmanship.
