Abstract

A component (3) for an air-treatment unit ( 1) : is provided, the component,(3) comprising a solid body (15) composing longitudinal channels (22) extending between first and second end faces of the body, a first set of channels extending; from a perimeter face (26) of the body towards an opposite side of the body (15) and a second set of channels (24),. which also extend from a perimeter face (26) towards an opposite side of the body. The first set of channels (23) orthogonally intersect the longitudinal channels (22) The second set of channels (24) tangentially Intersects the longitudinal channels (22), A third set of channels (37) may, optionally, also be provided. The third set of channels (37) extends from a perimeter face (26) and orthogonally intersects both the longitudinal channels (22) and the channels from the second set of channels (24), An air-treatment unit (1) comprising a housing (2) end a component (3) is also provided The use of the component (3) in an air treatment system is also disclosed.
