About this app

The Digiduct is a powerful tool designed for HVAC professionals, supporting everything from design calculations to real-time field verification. Built utilizing the equations and recommendations from the ASHRAE Fundamentals – Duct Design chapter, it ensures your calculations are accurate and reliable, saving you time and reducing errors.

Key Features:
• Multiple Shape Sizing Options: Supports sizing for rectangular, round, and flat oval ducts, offering flexibility for various duct designs.
• Customizable Dimensions: For rectangular and oval ducts, users can lock in one dimension, and the app calculates the other, ensuring precise results based on CFM, pressure drop due to friction, or velocity.
• Duct Location Intelligence: offers the user predefined parameters to use as starting point and reference when selecting duct sizes so users at HVAC experience level can make confident selections.

Why Choose Syska's Digiduct?
Unlike other duct sizing tools, Digiduct goes above and beyond. It doesn’t just provide basic size outputs—it evaluates the location and context of your duct (high-pressure vs. low-pressure, shaft vs. plenum), alerting you if your selection exceeds maximum pressure drop or velocity limits. This added layer of intelligence ensures higher accuracy and gives users confidence that their sizing is optimal for the application.

Get the assurance of precision with Digiduct—designed to meet the demands of real-world HVAC scenarios.

Ratings and reviews

Just tried it. Its OK, but when I go to settings to change, for example, the "duct roughness", or "altitude", it doesn't bring up the phone keyboard to be able to actually change these numbers

Calculations are quick and accurate, perfect for when I'm onsite and need to make quick calculations

Great app! Easy to navigate. Recommended for HVAC engineers and architects
