Ashrae Duct Fitting Database Version 60005 [portable] Jun 2026

In mechanical, electrical, and plumbing (MEP) engineering, precision in HVAC design is paramount. Calculating the pressure drop across a ductwork system determines the size of fans, energy consumption, and overall indoor air quality.

The is an indispensable tool for mechanical engineers, designers, and HVAC technicians. By offering a comprehensive, cloud-based, and graphically aided database of fitting pressure losses, it empowers professionals to design more efficient, reliable, and compliant air distribution systems.

If you walk into a modern skyscraper and feel a gentle, consistent breeze of conditioned air, you are enjoying the benefits of a silent war against chaos. That war is fought by engineers using the .

If you are designing data center cooling, hospital isolation rooms, or high-rise office ventilation, the precision offered by translates directly into capital cost savings (smaller fans, fewer silencers) and operational savings (lower energy bills). ashrae duct fitting database version 60005

Stay tuned for our follow-up post: “How to Convert DFDB 60005 Data into Excel Pressure Drop Matrices.”

This article explores the capabilities of the , particularly focusing on the advancements found in modern versions like 6.00.05 . What is the ASHRAE Duct Fitting Database?

ASHRAE Duct Fitting Database (DFDB) version 6.00.05 is a cloud-based design tool primarily used by engineers to calculate pressure losses and loss coefficients for over 200 HVAC duct fittings. Core Technical Features If you are designing data center cooling, hospital

A key aspect of version 6.00.05 is its cloud-based access model. Purchasers receive a to the web-hosted version of the database. This transition moves away from the physical CD-ROMs of the past toward a modern, always-accessible service. However, it's crucial to note that this version is designated as a single-user product, and multiple-user licensing is not available. In addition to the full version, ASHRAE also offers a free ASHRAE Duct Fitting Database Lite app on the Apple App Store, which allows users to perform pressure loss calculations for a subset of the 240+ ASHRAE fittings for quick, on-the-go estimates.

The ASHRAE Duct Fitting Database is a comprehensive digital tool provided by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). It provides loss coefficient tables ( Cocap C sub o

The latest iteration of the DFDB software introduces several enhancements designed to streamline the workflow for mechanical designers:

Each fitting is accompanied by a diagram that displays the necessary parameters for calculation, such as angle, radius, velocity, and aspect ratio. 4. Calculation of Loss Coefficients ( The core function is calculating the

The update includes refined Reynolds number adjustments for very low velocities (300-700 FPM), which is critical for terminal unit sizing at partial load.
