Directional exhaust filters like the 1417D-40 are designed to control airflow and particulate discharge in high-sensitivity environments. For teams managing air quality in medical, industrial, or cleanroom settings, this filter offers a targeted solution to reduce contamination risk and improve directional flow control. The video linked below walks through its design, installation, and performance benchmarks.

What you’ll learn from the video

  • Design features: The 1417D-40 uses a multi-layer filtration system with directional flow channels to minimize backpressure while maintaining high particulate capture rates.
  • Installation guidance: Step-by-step visual instructions for mounting, sealing, and integrating with existing exhaust systems.
  • Performance metrics: Lab-tested data on airflow efficiency, particle retention, and durability under continuous use.
  • Use cases: Ideal for surgical suites, pharmaceutical labs, and any setting requiring controlled exhaust dispersion.

FAQs

Unlike standard exhaust filters, the 1417D-40 channels airflow in a specific direction using internal baffles. This helps prevent recirculation and improves containment.
