POWERTEC 70326 Aluminum Blast Gate 4 Inch, w/ Anti Clog and Air Leak Seal

POWERTEC 70326 4-Inch Aluminum Blast Gate - Self-Cleaning Design POWERTEC USA 4" NOMINAL OD - CAST ALUMINUM BODY - SELF-CLEANING - LOCKING STOP Professional 4-Inch Aluminum Blast Gate (70326) Industrial Airflow Control for Peak Suction Performance

The POWERTEC 70326 is a professional-grade 4-inch Aluminum Blast Gate, specifically precision-engineered to provide an airtight mechanical valve for your workshop's dust collection network. This gate is the definitive choice for woodworkers who need to direct 100% of their collector’s CFM to a single active machine while isolating stagnant branches. Featuring a heavy-duty die-cast aluminum housing and a precision-ground steel sliding gate, the 70326 is built to withstand the high static pressure and abrasive chip-load found in industrial woodworking environments.

Constructed with an innovative self-cleaning groove design, this blast gate solves the primary failure point of standard plastic gates: the accumulation of wood dust in the sliding track. The 70326 features open-ended slots that allow compressed dust to be ejected during the closing stroke, ensuring a Laminar Airtight Seal every time. Whether you are calibrating a complex multi-tool ducting run or upgrading a stationary cabinet saw, this aluminum gate delivers the mechanical rigidity and leak-proof performance required for showroom-quality results.

Key Product Benefits:

• Self-Cleaning Mechanical Action: Integrated slots prevent dust buildup in the tracks for a 100% flush closure.
• Air-Leak Seal: Closed-edge design eliminates the suction loss common in retail-grade plastic gates.
• Industrial Durability: Cast aluminum body resists impact, cracking, and the static electricity of high-speed dust.
• Locking Axial Stop: Features a manual locking knob to ensure the gate remains in the desired position during high vibration.
• Precision Universal Fit: Nominal 4-inch OD ports connect seamlessly to standard 4-inch ID dust hoses.

UPGRADE FEATURE: The steel sliding gate is designed for rapid manual operation and long-term torsional stability. Technical Specifications
