Air travels smoothly through rigid spiral pipe, reducing the static pressure losses in the system and increasing the system's efficiency. Metal fittings designed to reduce friction in air handling systems greatly increase the efficiency of central dust collection systems.

Using flexible hose that's not designed for the dust collection can greatly reduce the efficiency of the system. Black polyethylene dust collection hose is designed to produce a minimum amount of static pressure loss and to stand up to the vacuum pressures produced in dust collection. Clear, wire reinforced dust collection hose has the added benefit of making clogs and buildups of debris in the system easy to spot and correct.

When it is necessary to connect separate pieces of flexible hose, use PVC dust collection hose fittings. PVC elbows produce far less static pressure loss in situations where an abrupt change of duct direction is required than a sharp bend in a run of flexible hose. PVC Y-connectors and T-connectors make quick and easy work of setting up branch ducts. Dust collection splicers make it possible to connect straight runs of hose, and dust collection couplings allow two or more fittings to be joined directly together.

In most cases, to achieve adequate dust collection at individual machines, you will need to use either automatic or manual blast gates to shut off the air flow to other machines that are not in use.

Automatic blast gate systems are an extremely convenient solution. Both the Ecogate Blast Gate System and the JDS Automated Blast Gate System open the correct blast gate and turn on the dust collection system when you flip the power tool's switch. An added feature of automatic systems is that they prevent you from forgetting to turn on the system and open the correct gate.

For a more budget economical solution, manual blast gates will work perfectly well. Rockler offers plastic blast gates designed for use with flexible hose and PVC fittings and metal blast gates that can be used with either flexible hose or metal pipe. Blast gates designed specifically for use with spiral metal pipe are listed along with the spiral pipe and fittings offer.

The dust collection performance for many open stand table saws and jointers can be greatly improved with the installation of a dust collection hood. The hoods can be easily adapted to fit most contractor-type table saws and 6' and 8' jointers and are designed to work with 4' dust collection hose. For router tables, use the universal dust port. The universal dust port's flange attaches with screws and can be used with 2-1/2' dust collection hose or 2' shop evac hose.

For tools with no direct dust collection attachment, or to enhance primary dust collection, use a tabletop dust fitting or a free-standing universal dust collection port.

If you are setting up a portable dust collection system, quick release connectors such as keyed hose clamps and quick disconnect dust collection fittings will make moving your dust collector from machine to machine quick and easy. For stationary systems, they will make set-up, cleaning and inspection much less time consuming.

In general, it is better to use large diameter hose for longer runs and step down to the correct size for machinery dust ports as close to the machine as possible. Using the wrong-sized or makeshift adapters to step down hose diameter creates unnecessary drag on the system. Reducers designed for use with dust collection hose make transitions between hose diameters as smooth as possible. The universal duct adapter allows transitions between any combination of the most common hose diameters. The dust collection hose adapter allows 4' hose to be connected to most standard 2-1/4' bench top tool dust ports.

Static electricity build-up in your system's ductwork presents a fire hazard and can produce an electric shock on contact.  When properly installed, a dust grounding kit will greatly reduce the static electricity build-up in your system's ductwork.

Dust collection separators increase the waste holding capacity of your dust collection system by separating out larger sized chips and shavings before they reach your dust collector.  They also reduce wear on your dust collector's blower assembly caused by collisions with large debris particles.
