The 3M 7093 Cartridge/Filter is designed for air sampling and detection of hydrogen fluoride (HF) gas, serving as a level indicator for refrigeration systems. It is compatible as a replacement part for 3M models FC1002 and FC1004, making it a reliable choice for maintenance and safety monitoring applications.
Hydrofluoric acid (HF) is a highly corrosive, colorless, fuming liquid that poses serious hazards — including eye and skin damage and potentially fatal effects if inhaled. This cartridge/filter helps protect workers and facilities by providing accurate HF gas level indication where exposure risk is present.
