Professional Dust Collector Lower Collection Bag (70351)
High-Visibility Debris Management for Large Extractors
The POWERTEC 70351 is an industrial-performance 20-inch diameter lower collection bag, specifically precision-engineered for use as the primary debris reservoir in single-stage dust collection systems. Designed to fit filter drums ranging from 19" to 20", this bag is the definitive choice for woodworkers who need a reliable, high-capacity solution for wood chips, sawdust, and heavy shavings. Crafted from ultra-thick, reusable polyester, it offers exceptional resistance to the abrasive impact of flying debris and the thermal stress of dry heat applications.
What sets the 70351 apart is its user-focused design: an integrated clear viewing window allows you to monitor dust levels at a glance, preventing overfills that can back up into your impeller. Additionally, the heavy-duty bottom zipper simplifies the disposal process—allowing you to empty the bag directly into a waste container without removing the entire clamp assembly from the machine. Whether you are running a cabinet shop or a home hobbyist workshop, this bag ensures a cleaner environment and peak vacuum performance.
- Clear Window Monitoring: Eliminate guesswork by visually checking debris levels without stopping the machine.
- Rapid Bottom Disposal: Sealed zipper allows for efficient emptying, reducing maintenance downtime.
- 30-Micron Filtration: Acts as an effective secondary filter for large particles while maintaining high CFM.
- Universal 20" Diameter: Compatible with most 1.5 HP to 2 HP systems from Grizzly, JET, WEN, and Delta.
- Heavy-Duty Polyester: Durable, tear-resistant material designed for long-term production use.
