Grizzly Industrial 5-Speed HEPA Hanging Air Filter

The T33151 Large Advanced Hanging Air Filter clears the room of the fine dust particles that your dust collection system doesn't capture.The air filter can be set to operate in five air flow speeds between 800 and 1400 CFM. To cycle through the available speeds, press the Fan Speed button on the control panel or remote control repeatedly.HEPA stands for high efficiency particulate air. The HEPA filter in the T33150 traps small, harmful particles, such as saw dust, pollen, pet dander, and dust mites down to 0.3 microns with a MERV-17 rating at 99.97%.For reference, a human hair is between 50-70 microns in diameter, meaning the T33150 collects particles 230 times smaller!A quick glance at the built-in filter quality monitor indicates when the primary HEPA filter or the secondary, activated carbon filter (which traps odors) needs replacing. A blue light on the control panel or remote control indicates normal operations; a red light means the filter needs replacing..The air filter can be set for a timed performance of 2, 4, 6, or 8 hours. At the end of this time, the air filter will automatically turn OFF.The Auto function detects the air quality and adjusts filtration speed based on the current air quality. When enabled, the Auto indicator will shine blue on both the control panel and remote.Made in an ISO 9001 factory.
