An emitter unit comprises a wall defining an elongated flowpath, an inlet and an outlet for the unit, a connector for coupling the unit to an irrigation installation, two sets of oppositely directed baffles projecting into the flowpath, characterized in that each baffle terminates in a baffle tip of a width xi where 0< xi <0.25 DELTA where DELTA is the minimum throughflow spacing in the emitter, the baffles of one set being respectively directed towards the inter-baffle regions of the opposite set, the tip of each baffle being substantially aligned with the tips of the opposite pair of adjacent baffles. |
