Ventraze Duct Airflow

Ventraze turns a manual duct traverse into a clear field record. Enter twelve velocity readings in a 4 × 3 plane, add the duct's internal width and height, then see the arithmetic mean and estimated airflow. Work in metric or imperial units and compare a completed reading with a target flow.

Each job keeps its site, duct location, technician, date, notes, dimensions, and readings on this device. A completed job can be shared as a one-page PDF showing the result and all twelve points. Switch units while preserving the same physical measurement.

Bring your own velocity meter: Ventraze does not connect to instruments or measure air speed itself. The estimate is based on manually entered readings and rectangular duct area. Check sampling position, meter calibration, units, and site conditions before relying on a report. The app does not certify a standard or provide compliance documentation.

A clearly labeled example job shows the workflow on first launch; delete it or create a blank job to start. No account, ads, subscription, analytics, tracking, or cloud upload. Works offline.
