HEPA After Filter

Superior Safety & Risk Reduction

Extra Assurance

As a final purifier of the air coming out of your RoboVent dust collector, a HEPA After Filter is available to mount atop your unit. Standards for HEPA (high-efficiency particulate arrestance) filters are set by the U.S. Department of Energy and are the gold standard for air purification. Particulate allowances for HEPA filters are exceedingly small, measuring in the tenths of a micrometer in size.

HEPA After Filters are especially popular in welding facilities. Weld fumes can contain toxic substances such as hexavalent chromium, and this filter is extra assurance that workers are safeguarded and that air quality standards are high.
