The Holyoake OHL-DRC is a precisely made closable, drainable weather louver. The blades feature a special gutter, so each blade only deals with the water that lands directly onto it. Therefore, water does not stream down the front of the louver, but is directed by means of an internal drain element to the external base of the louver, rather than into the building. The side cavities are sealed to prevent moisture penetration. In addition to the special drainable blades and water penetration cavities, the OHL-DRC also offers the unique combination of a closable louver, operated by a manual handle or via a suitable motor. This provides the facility to fully or partially close the louver automatically when linked to a moisture or rain sensor, or other building management system.
