Abstract
In a ventilating hood of the type incorporating a supply chamber, an exhaust outlet, one or both of which incorporate air blower or moving means, such as fans, pressure taps are incorporated at strategic locations about the supply and exhaust chambers, generally at the location of their separating partitions, as where the air is diffused as passing through the hood, so that pressure drops can be readily determined, and airflows at these locations may be properly set as determined from previously prepared graphs.
