Small-scale facility for measuring air-flow resistance and air-leakage rates

This facility can determine the air-flow resistance of domestic scale ventilation devices such as trickle-vents, tile and ridge terminals to BS EN 13141-1:2004. It can also determine the air leakage through products such as loft access traps and downlighters

The facility can accurately measure pressure differentials from 1-500 Pa and flow rates of 0.3-100 l/s (calibrated orifice plates); air density corrections are applied according to prevailing environmental conditions.
