M However in order to measure accurately over this wide range the range must be changed as described in the following section The Infiltrometer fan blade pushes air out the back of the fan creating a negative pressure in front of the blades This negative pressure pulls air through the fan s rounded venturi shaped inlet More negative pressure more flow The Infiltrometer has been calibrated so for each size of inlet opening and for each negative pressure Flow Pressure the flow rate in cubic feet per minute CFM is Known As flow decreases the Flow Pressure decreases eventually to the point that it becomes too low to read accurately By reducing the size of the inlet with the restrictor plate a given amount of air is forced to enter the blower at a higher velocity resulting in a much higher flow pressure The fan speed must be increased in order to pull the same quantity of air through the blower with the restrictor plate in place Therefore as the flow rate requirement decreases such as in tighter buildings the size of the blower inlet must decrease to maintain a high and accurately readable Flow Pressure Each inlet size has a pre established configuration or range Ranges are somewhat analogous to gears in a standard transmission car The slower you go the lower the gear Changing Ranges The Retrotec 2000 Series Infiltrometer blower has 7 flow ranges for the greatest possible accuracy and versatility Range 22 wide open with no
