Users can combine multiple sections of ductwork that vary by size and shape to calculate a total allowable leakage. The application uses the method outlined in SMACNA’s HVAC Air Duct Leakage Manual, and provides suggested leakage classes from SMACNA’s latest edition of the manual. The method used is compliant with ASHRAE 90.1, IECC, IGCC Version 2, IMC and the UMC.
This is a Simple Air calculator. We are an HVAC company and this simple calculation has been very well used by us over our 75 years in the HVAC business. We hope you too, will find that it's a helpful app to have around. Calculations are made using The American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) Fundamental equations.

WESTAFLEX® is a large global HVAC brand, owned by German company Westaflex Holding. The company began in 1933 when Lorenz and Ferdinand Westerbarkey, formerly prisoner of war during the Nazi era developed a coil-based tube forming maschine, the first stable and any-shape tube of its kind. The company's owner, named it Westaflex, from their family name Westerbarkey (meaning Westerflex HVAC products). Internationalisation during the 1960s propelled the WESTAFLEX brand to a wider global market. With presence in 32 countries on five continents, Westaflex engages in the majority of their business within Europe and North America.
--- This Professional Ducting Design Software is a fast analyzer tool for you 2D Contractor submitted drawings.
--- The Application works like an old hand held ductulator.
--- The change is that you can review a contractors drawing and know about the Main duct Velocity and friction rate which is not mentioned on the drawings.
--- Once the Main Duct Parameters are established one can analyse the rest of the ducting.
BEST Feature :
----VERY Important and USEFUL TOOL which will go with the modern new age analyses i.e You can export the designed ducts to Drawing Exchange Format DXF which can be brought inside AutoCAD, or Navis Works or any 3D package to check interference. use etools to view on android mobile or AutoDESK 360
The scenarios for the app are limited to joint lengths of 4, 5, and 6 feet. The transverse connections are limited to T1 (flat drive), T5 (flat slip), T10, 11, and 12 (standing slips) and T25 a or b (TDC/TDF). Where appropriate the app will also provide options for intermediate reinforcement. The full range of reinforcement spacing options is 6, 5, 4, 3, 2 ½, and 2 feet.
In most cases the app will provide options for internal reinforcements and external reinforcements. Internal options are limited to EMT conduit tie rods and external reinforcements are limited to angles. Enough information is provided so users can choose other options from SMACNA’s Standard.
The output of the app is a written description of the duct as well as a graphic representation. Users can view the report on-screen or email it.
This app does not provide every possible solution found in SMACNA’s standard and it will not provide every detail. For example, the app does not provide requirements for the proper attachment of the reinforcements. The app is intended to be used in conjunction with SMACNA’s HVAC Duct Construction Standard.
The calculation is performed assuming that the pressure drop per unit length along the pipe is a constant.
The Øeq hydraulic diameter corresponds to the diameter of a circular channel that would cause the same loss of load of the real geometry, equal to resistance coefficient of the motion of the air.
After calculating the app will send to your e-mail address a text file with all the channels' branches calculated.
This application was initially developed for a friend and we decided to share it.
It supports different units depending on the calculation which is used:
- Rectangular/Square duct
- Circular duct
- Smoke extraction
You can use Gesture to switch between screen, clean the screen, ...
You can also send your result by email to work on them later.
If you need more units, feel free to contact us.
The application is available is English & French.
If a special item is not in our catalog, we will utilize our ability to build the tooling to manufacture it for you because your success is our success!

1. Duct Sizer: This module allows you to quickly size one HVAC duct run or a range of duct sizes for a wide variety of duct materials and shapes.
2. PT Chart: This module is an electronic pressure-temperature (PT) look-up chart that allows you to specify the exact refrigerant temperature/pressure and view the corresponding pressure/temperature value. It also displays a complete list of pressure/temperature values in 1 degree increments for over 70 different refrigerants. You can adjust the elevation so proper gauge pressures are displayed. Additional functionality includes the ability to display specific refrigerant properties and email the entire PT chart list for a specific refrigerant.
3. Capillary Tube Calculator: This module allows you to perform capillary tube look-up based upon HP, condenser cooled type, and refrigerant type.
4. Store Locator: This module allows you to find the closest Johnstone Supply store to where you are currently located. You can also type in a zip code to find all Johnstone Supply stores within a specific radius.
5.AC/Gas Furnace Efficiency Savings Calculator: This module allows you to quickly calculate the energy savings for cooling or heating based upon selecting the old/new unit information and your region.
This program will give the hydraulic round diameter of a duct and the friction rate.
You can then calculate the duct height knowing the width...
Please watch out for PRO version which shall cover a bigger range with more features. This PRO version shall be chargeable.
