A duct size calculator, commonly known as a ductulator, depends on factors like the size of the space you’re heating or cooling, air flow velocity, friction loss, and available static pressure of the HVAC system.
Duct systems are often divided into three pressure classifications: Low Pressure Systems - where fan static pressures are less than 3 in WC (750 Pa) and duct velocities in general less than 1500 fpm (7.5 m/s) Medium Pressure Systems - where fan static pressures are in the range 3 to 6 ...
Using a predefined air velocity, DuctCalc.Ca Ductulator App calculates the diameter of round duct and the other dimension of a rectangular duct. Based on the calculated dimensions, the static pressure loss will be calculated for both duct shapes and dimensions. Note that unlike conventional duct...
简介 The Duct Calculator App is a modern take on a the classic duct sizing wheel. HVAC engineers, designers and contractors quickly and accurately size a new duct or calculate the performance of an existing duct on your Mac. Size both round and rectangular ductwork with the ease of a traditi...

Holds 22 ft (6.7 m) continuous water head pressure and up to 90 ft (27 m) surges VERSATILE Can seal conduits of all sizes and complex cable configurations RE-ENTERABLE Duct sealant can be removed for future cable installations COMPATIBLE ...
It mentions having a sensor that "monitors the static pressure" to adjust the fan RPM as needed, and does not provide any complex/detailed duct requirements beyond that note, and coming equipped for both 4 and 6in ducts out of the box. My intent is for it to run at ~50CFM for gene...
