VentCalc, a Ukrainian ventilation configurator

Field notes

VentCalc presents multiple selection paths for ventilation work, including airflow-based design, product lookup by code or dimensions, photo-based identification, and pasted specifications. Its catalog is divided into 34 product families, while the calculation view is described in terms of noise, throw distance, pressure drop, velocity, and price. The site also names concrete outputs—commercial-proposal PDFs, customer share links, 3D views, and mounting DXF files—and identifies price lists, manufacturer catalogs, or engineering estimates as sources for values.
