Product Description:
Holyoake’s OHL-D drainable blade louver offers excellent water penetration performance, which it achieves by draining water from each blade before discharging it at the bottom of the louver through vertical down pipes. In a typical horizontal louver, where water cascades down the face, the water builds to a level where the pressure differential and the velocity of air over the louver is enough to carry over the water to the inside of the louver. By avoiding this cascade effect, OHL-D drainable horizontal louver delivers a higher effective velocity without compromising the water penetration performance.
