Barnebey Sutcliffe stocks HEPA filters that handle airflow up to 2,000 scfm, and a minimum efficiency of 99.97%. All HEPA filters are designed for seamless installation in all Barnebey Sutcliffe equipment. It is recommended that HEPA filters be preceded by a prefilter to capture larger particles and increase HEPA life.

A prefilter is the primary layer of filtration that collects large particles before they reach the HEPA filter. They are designed with a low pressure drop and are often changed more frequently than the HEPA filters in the system. The primary advantage of the prefilters comes from extending the life of the expensive HEPA filters and gas/odor cartridges by preventing dust from coating and clogging the HEPA filters. Prefilters can be made of either fiberboard, galvanized or aluminized carbon steel.
Activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low oxygen spaces should be followed, including all applicable Federal and State requirements.
