SLLF series filter is composed of two single bowl filters and one 2-position 6 way
directional valve. It is simple in construction and easy to use. There is a by-pass valve and two contamination indicators in it, for protecting the lubricating system safety.
The feature of this filter allows continuous operation even if the clogged element
needs replacing for a clean one. After opening the balance valve and then turning the directional valve, the other filter will begin to work in the lubricating system; the clogged element should be changed at that time. This series filter is used in lubricating systems of heavy duty, mining and metallurgical machines.
