About this manual

The Gaoyuan VN spiral drainage nozzle is designed for pulse dust‑removal systems with 3/4" and 1" blow‑pipe diameters. By balancing the airflow inside the pipe, it distributes compressed air evenly to each blow hole, improving dust‑blowing efficiency and reducing resistance.

The document lists installation guidelines, dimensional data, applicable temperature range, material (PA‑6), and detailed model specifications such as nozzle length, weight and thread type for various VN‑20 and VN‑25 variants. This manual is written in Chinese.
