01 / Engineering Overview
Axial Smoke Exhaust Fan for Emergency Fire Ventilation
HTF-Ⅰ is a single-speed axial-flow fan intended for emergency smoke extraction and high-temperature exhaust duties in fire-protection ventilation systems. The series covers nominal fan sizes from No.3.5 to No.15.
Selection should be based on the required smoke exhaust airflow, system resistance, temperature duty, installation arrangement and electrical requirements rather than fan diameter alone.
Fire Smoke Exhaust Is the Primary Duty
Project fire temperature, required operating duration and applicable local fire-safety standards should be confirmed before final production and quotation.
02 / Fire & Temperature Duty
Temperature Duty Must Match the Fire-Smoke Requirement
Emergency Duty
Designed for emergency smoke extraction rather than ordinary continuous comfort ventilation as the primary operating condition.
Smoke Temperature
Specify the required fire-smoke temperature and operating duration when requesting selection or quotation.
Normal Ventilation
If one system must also provide daily ventilation, state the normal operating airflow and control requirement separately.
Compliance
Required local fire code, project specification, test standard and documentation package must be confirmed for each export project.
03 / Construction
Compact Axial Configuration for Smoke Exhaust Systems
01
Axial Impeller
Axial-flow impeller matched to the required airflow and pressure duty point.
02
Cylindrical Casing
Compact inline casing suitable for connection to smoke-exhaust ductwork.
03
Motor Assembly
Motor configuration is selected according to fan size, operating duty and project electrical requirements.
04
Mounting Base
Base and casing dimensions vary by size and should be checked against the installation drawing before fabrication of supports.
