K-FLOW Aviation Filter Monitors are simple compact units which can easily be installed and serviced. They are developed in particular for mobile fueling installation and can be delivered in two versions. Type FFM without and type FFMI with interlock system.
The K-FLOW Aviation interlock system is an additional safety device designed to prevent closure of the cover should the full amount of monitor elements not be fitted. The interlock prevents unfiltered fuel being delivered if an element is missing.
