The cylinder contains one cubic foot of volume. Out of Stock : Add to Cart. That allows the test chamber to provide the air speed in a measurement of cubic feet per minute. A greasy exhaust fan will clog up the works in more ways than one. I compared a 40 mm case fan and a 50 mm blower fan, pairing them with four popular styles of fan shroud (airflow shapers) and no shroud at all. An exhaust fan's static pressure, also known as its pressure drop, describes the resistance the fan must overcome. To search by size, you'll want to measure the core area of your radiator and match to overall sizing of the fan shroud.
