Duty-based selection
Compare airflow and pressure at the required operating point, including installed system losses.

This project is based in Shangyu, Shaoxing, a major ventilation-equipment manufacturing cluster in Zhejiang, China. The site is being built around clear product data, practical selection inputs and traceable source material.
Fan model names alone do not define suitability. Selection begins with airflow, pressure, medium, temperature, installation, duty cycle, power supply and required standards.
The website preserves source product references internally while presenting rewritten English descriptions, normalized units, SEO-friendly URLs and application-based navigation for overseas buyers.
Published ranges are useful for initial screening, but final selection must be checked against the actual system and destination requirements.
Compare airflow and pressure at the required operating point, including installed system losses.
Keep source IDs, original pages and images linked to every normalized English product record.
Organize equipment around buildings, tunnels, factories, roof exhaust and process ventilation.
Present the regional manufacturing base clearly for international procurement and project communication.
