    The Duct Calculator provides extensive computing functions for dimensioning of round and rectangular ventilation ducts. The input of the desired size (volume flow, air velocity or dimension) can be selected. By entering text or slider the requirements are defined and determined the required size and the pressure loss per meter.

  • IRIS Dampers

    An IRIS damper size should be chosen such that the desired range of airflow falls within the damper's performance curve. Select a mid-range setting on the curve. This not only establishes the required duct size, but also provides the user with balancing flexibility should airflow requirements change.

    The springs are sized for exhaust fans which are typically more airflow in the same size duct. Asked on 2020-07-26 by Patrick #2: Q: Can the damper be used in a horizontal position but in downflow? A: No. The spring/damper weight is balanced for upflow (upwards exhaust air flow) or sideways flow. It would not close if installed upside down.

    Ordinary heating, ventilating, and air conditioning duct systems read air pressures at 0.4 psi or less, often much less. 1 psi equals 27.7 inches of water gauge; a common duct pressure of 0.25 inches water column is equal to (0.25 divided by 27.7 in-wc/psi) = 0.009

  • How do I calculate return duct size?

    I already learned from reading other posts my return grills are too small. How do I calculate if the return ducts are too small, too? I have a three ton downflow furnace a/c. I have two return ducts, hard metal round, one 14 inch and one 12 inch. How many square inches do I need to get the right airflow for 3 tons? Both returns are above the ceiling, with lengths of 12 and 8 feet, two ninety

    duct design sizing techniques, such as a constant 0.1 in. w.g. per 100 ft friction rate (80 Pa per 100 m) for duct mains, this technique uses a higher starting velocity and friction rate and then keeps the duct main the same size for long distances, e.g., up to 60 ft (18 m). This results in lower first costs due to eliminated fittings but re-

    The Equal Friction method creates an initial estimate for duct sizing based on the constant pressure loss per unit of duct length specified (default is 0.10 in-wg/100 ft or 25 Pa/30 m). The Equal Friction and Static Regain methods used in Revit use the ASHRAE Duct Fitting Database, Version 5.00.00, which contains information about losses for

    A zoning system can typically use the same duct sizing as a traditional single-thermostat system. It is important to properly size and install a pressure relief damper as well as properly balance the zones. To minimize bypass air flow, increase the duct capacity by one size for each zone less than 25% of the total system air flow capacity.

  • Damper Actuator Sizing Chart for Selecting HVAC Dampers

    One of the most frequent problems that technicians face is how to determine the correct torque actuator for their damper. These tables should help. First determine the size and type damper, then determine the air flow that the damper needs to open and close against. From that point, use the charts below to determine the amount of torque needed.
