A debris removal device for subterranean use features a debris laden inlet tube within a housing to define a debris collection space at the lower end of the housing. An eductor draws the debris laden fluid to the top of the inlet tube where the flow stream is returned to a downhole direction with discrete passages formed between the housing and the inlet tube by spaced parallel plates.

As a result flow heading back downhole can release debris and turn back uphole in passages defined between the outside of the plates and the inside wall of the housing. The tabs allow the flow turning uphole to make a greater radius turn because of a crossing over effect created by the tabs. There is less turbulence and narrower width to the flowing stream going uphole.
