High static pressure duct fans
WebHigh vs. Low Static Pressure Pressure that’s too high or low is usually caused by improperly sized equipment. An oversized furnace can be too powerful and cause high static pressure inside your ductwork. An undersized furnace won’t be able to move enough air through the system to keep you comfortable. WebJan 15, 2024 · Possible reasons for high static pressure in your duct system at: A blockage in the ducts; Closed dampers; Offset flex duct; Restrictive filters; When the static pressure is too low, it means that there’s a leak somewhere on the way. Possible reasons for this are: Missing filters; Leaks in the duct pipes; Low fan speed; Separated duct sections
