The welding quality technical requirements for the ventilation fan of HTF stainless steel smoke exhaust axial flow fan are mainly these. We must operate correctly according to the above instructions, only in this way can its performance and safety be guaranteed, thereby improving our work efficiency.

1. The performance listed in the performance table of the fan is within the high efficiency range, divided into five performance operating points according to the air volume. When selecting, the performance table shall prevail. The qualified products of the factory fan shall have a total pressure error of no more than ± 5% at the rated air volume. The performance selection table shall be based on the performance under standard conditions, and the performance specified in the technical documents or order requirements shall be subject to the standard conditions;

2. The installation methods of stainless steel smoke exhaust fans can be divided into horizontal and rooftop types, with special requirements for performance such as air volume, total pressure, and installation size;

3. HTF-I and HTF-II refer to atmospheric pressure exhaust fans, with axial flow blade types: HTF-I (single speed) and HTF-II (dual speed); HTF-III and HTF-IV refer to medium pressure firefighting and high-temperature smoke exhaust systems;

4 HTF-X is a silencing type fire high-temperature smoke exhaust fan, and users can choose different types according to their actual needs;

5. The HTF-W series roof mounted high-temperature smoke exhaust fan allows users to choose flame-retardant fiberglass wind caps or steel wind caps according to their actual needs.
