Air-Pulse Flow Control Valves for Filter Cleaning
Designed for use in dust-collection systems, these normally closed diaphragm valves periodically burst air to knock debris from filters. Connect the valve’s inlet port to your air supply, and connect the outlet port to the blow tube in your system.
A solenoid is required to actuate the valve.
Flow coefficient (Cv) is a measurement that indicates how much airflow a control valve can provide to your cylinder.

Self-Cleaning Blast Gates
Use in dust collection systems. The slide pushes through the top of the gate to clear debris. These blast gates control the flow of air and material through duct systems. The locking screw holds the gate’s slide in position.
Aluminum is lighter in weight than stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than galvanized steel.

Automatic Blast Gates
More convenient than other blast gates, these automatic gates open and close in sync with dust collectors, fume exhausters, and other machines to control the flow of air and material. The double-acting air cylinder moves the gate.

Design-Your-Own Dust Collector Duct System
Use these components (sold separately) to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations. Hose clamps are available.
For maximum safety and to avoid a dangerous buildup of static electricity, you must use the grounding kit (sold separately).
If you need more information on designing and installing a dust collection system, order our book "Dust Collection Basics."
Dust Hoods for Angle Grinders
Connect these dust hoods to your vacuum system to contain and remove dust and fine particles while grinding or cutting. They fit all major brands of angle grinders, including DeWalt, Milwaukee, and Makita. These dust hoods are OSHA compliant for point-of-origin dust containment. To attach these dust hoods to a standard 2" dia. vacuum hose, they either include an adapter hose or you can add a vacuum adapter (sold separately).
Dust hoods for cutting cover the wheel of your angle grinder while tuck-pointing and crack chasing.
ABS dust hoods are disposable, so they’re good for quick jobs. Cut away the front edge of the hood to grind close to a wall or an edge. They don’t come with an adapter hose.
Nylon dust hoods contain glass filler, so they’re durable and resist abrasion. They have a sliding front edge for grinding close to a wall or an edge.
