This technical manual introduces the features and application range of the spiral drain nozzle, as well as installation and usage considerations.
This manual describes the GOYEN VN spiral drainage nozzle, a device that balances airflow inside the spray pipe and distributes compressed air evenly to each nozzle, improving dust removal efficiency. It also explains how the nozzle can be installed on pulse valve outlets or directly on spray pipes to enhance cleaning performance.
The document lists applicable pipe sizes (3/4" and 1"), operating temperature limits (‑40 °C to 80 °C), material (PA‑6), and provides model‑specific dimensions and connection types. Installation notes and dimensional data are included for proper integration into pulse dust‑removal systems. This manual is written in Chinese.
| Material | PA-6 |

It balances the airflow inside the spray pipe and distributes compressed air evenly to each nozzle, improving dust removal performance.
The nozzle is not suitable for use above 80 °C and is rated for temperatures from –40 °C to 80 °C.
The VN nozzle fits pipe diameters of 3/4 inch and 1 inch.
It can be installed directly on the pulse valve outlet or tightened onto a welded nut at the bottom of the spray pipe.
