The adsorption of critical gases from the cathode air can cause irreversible damage to the catalyst of fuel cells that leads to a loss of performance. The ENTARON FC cathode air cleaner extends the service life of the fuel cell system by reliably protecting the catalyst from these gases. It also protects the system from channel blocking and wear by separating particles from the cathode air. Compact Housing Concept Tool-less and easy service due to color-coded comfort fasteners Flexible configuration of the raw air inlet and freely positionable 90 degree elbows, with integrated MAF connection on request Simple Installation by integrated brackets on the housing with through-holes or threaded inserts
