Professional 3-Inch Aluminum Blast Gate for Dust Collection (70165)
Precision Airflow Directing for Compact 3-Inch Dust Networks
The POWERTEC 70165 is a professional-grade 3-inch Aluminum Blast Gate, specifically precision-engineered to manage the complex static pressure requirements of smaller workshop extractors. This gate is the definitive choice for woodworkers who need to execute surgical airflow redirection between stationary tools without the "bleeding" suction loss common in plastic variants. Featuring a rugged die-cast aluminum body, the 70165 series provides the structural rigidity required to withstand high-velocity wood chips while maintaining a 100% efficient mechanical seal.
Constructed with a unique self-cleaning architecture, the internal steel gate facilitates a Clog-Proof Sliding Action. As the gate cycles axial to the housing, it scrapes away built-up resins and fine dust into an open rear slot, ensuring a perfectly flush closure every time. The integrated locking knob provides a stable friction-fit to prevent the gate from "creeping" under high vacuum load. Whether you are rigging a compact CNC enclosure or a specialized sanding station, this aluminum blast gate delivers the airtight securement and industrial durability required for showroom-quality results.
- Self-Cleaning Groove Logic: Engineered with a specialized slot that clears debris as the gate slides, preventing the common "half-closed" leak mode.
- Die-Cast Aluminum Build: Industrial-strength housing resists the abrasive nature of sawdust and provides elite long-term durability.
- Zero-Leak Axial Path: Precision-machined steel gate ensures a tight seal to conserve air volume and maximize tool-head suction.
- Integrated Position Lock: Features a threaded knob to secure the gate in any position axial to the flow, ideal for regulating CFM.
- Universal 3" Compatibility: Tapered 2-15/16" O.D. ends provide a seamless friction-fit with standard 3-inch I.D. hoses and fittings.
