Combined Tenkay filtration systems are 2-stage pulse systems with a final static EPA filtration stage that is designed to protect rotating machinery operating in corrosive and high dust load environments. The first pulsing stage is designed for extremely dusty environments. The self-cleaning action during operation allows continuous operation at low stable pressure drop, eliminating the need for frequent replacement of static pre-filters. The cleaning system is activated as a function of the dust load and avoids sudden increases in pressure drop. The final stage of EPA filter provides a barrier against the smallest and most corrosive particles which has been proven to significantly reduce or eliminate corrosion and fouling. As well, the water repellent design provides protection under even the highest humidity levels. Our Combined Tenkay UpFlow & Static 2-Stage Filter Housings is a gas turbine protection system has the following benefits:
