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. Secondary Element Strong Protection against dust for applications in high-pollution-territories Best possible security for engine during servicing
