PARTICLE INTERCEPTOR

An interceptor having a filter chamber, an inlet passage connected to the filter chamber at an inlet opening, and an outlet passage connected to the filter chamber at a n outlet opening. The outlet opening is above the inlet opening and has a minimum outlet flow elevation at which fluid can pass therethrough. A filter may be in the filter chamber between the inl et and outlet openings such that fluid passing from the inlet opening to the outlet openin g must pass through the filter. A bypass passage fluidly connects the inlet passage to the outle t passage. The bypass may have a minimum bypass flow elevation at which fluid can pass through the bypass passage, the minimum bypass flow elevation being higher than the minimum outlet flow elevation. The bypass may be adapted to allow flow therethrough only when a flow resistance between the inlet and the filter exceeds a threshold value.
