• Cleaning System: MaxPulse™ pulse-jet cleaning system requiring compressed air (approx. 90–100 PSI) for automated, online reverse-pulse filter cleaning.

Key Features & Applications

• Triagonal Filter Design: Features Donaldson's proprietary triangular-shaped cartridge filters, providing up to 27% more media at the bottom of the filter to assist in efficient dust dropping into the hopper.
• Downflo Downward Airflow Pattern: Directs dirty incoming air downward alongside gravity, reducing re-entrainment of dust cake during pulse cleaning.
• Target Applications: Commonly used across pharmaceutical powders, food processing/nutraceutical dust, metalworking, chemical powder handling, and general industrial process dust extraction.

Estimated Footprint & Dimensions

• Base Collector Dimensions: Approx. 48" W × 101" D × 140" H (height varies depending on stand/hopper layout and drum attachment).
