Exhaust & Process Ventilation
For process fume, odor and dust, exhaust is organized from the source and conveyed through ducting to the discharge point. Centrifugal fans and cabinet centrifugal fans suit ducted exhaust and process air.
Ventilation solution
Factory & Industrial Ventilation Solutions
Factory production often involves fume, heat, odor or dust, requiring organized supply and exhaust paths. Xin Changfeng matches centrifugal fans and other industrial ventilation equipment to media conditions, system resistance and duty.

System Resistance & Selection
Ducts, elbows, dampers and purification equipment all add resistance. Selection requires calculating airflow and total pressure, and confirming how media temperature and dust/oil affect the impeller and motor.
Supply & Exhaust Layout
A good air path brings fresh air in and removes pollutants close to source, avoiding short-circuiting and dead zones. Supply and exhaust should be zoned to match and run together.
FAQ
Factory Ventilation FAQ
Workshop size, heat and pollution source locations, media temperature and dust content, target air-change or exhaust volume, duct routing and system resistance, plus installation and power conditions.
Centrifugal fans suit ducted exhaust and process air with higher pressure; axial fans suit high-volume ventilation with low resistance. Confirm by total pressure and airflow.
Place exhaust near the source, keep supply and exhaust separated and zoned, and use airflow balancing and guiding where needed.
