Manual filters for fuel and lubricating oil

---

Alfa Laval automatic filters are used for full-flow filtration of fuel or lubricating oil. To ensure redundancy and/or the highest level of security, most marine installations require manual filters as a complement to automatic filters. The filters are used for two important applications in the circuit for full-flow filtering of fuel and lubricating oils for trunk piston and crosshead engines: (1) for the bypass system and (2) for the indicator system.
