Lechler Inc. is rolling out octagonal flat fan replacement shower nozzles in spray angles ranging from 15 degrees to 75 degrees, as well as round 0 degrees, or solid stream (needle jet) versions. These nozzles come in a wide range of flow rates. The flat fans, due to their octagonal shape, are self-aligning when used with STAMM bases. STAMM created the original ďbrush and flushĒ shower system, including patented designs for the mountings. These showers are widely used in pulp and paper mills and in wastewater treatment plants.
