TA HT 400
Vane axial smoke extract fan made of steel and aluminium for use in mechanical smoke extract systems.
Application
For use in ducted mechanical smoke extract systems, particularly applications that require an absolute conformity to high specifications in terms of pressure and air volume. Suitable for running in a range of temperature from -20°C to + 70°C.
Description
The VA-HT Series smoke extract fans consist of a long steel casing for easy installation and a high performance axial impeller with aerofoil blades made of aluminium. Designed for evacuation of smoke in the event of a fire, they ensure tenable conditions are maintained for escape and entry of emergency services.
The smoke fans are available in sizes from a diameter of 400 mm to 1600 mm (bigger sizes upon request) for performances ranking up to 230 000 m³/h and 2400 Pa. Higher pressures can be reached with two fans installed in series.
Features and benefits:
- Impeller balanced according to ISO 21940-11.
- Fixing flanges manufactured according to UNI ISO 13351 standard.
- Asynchronous three-phase IE3 motors according to international standards IEC 60034, IEC 60072, EMC 2014/30/UE, LVD 2014/35/UE.
- CE marked.
- Suitable for S1 service at constant load.
- Range of pitch angles can be set during assembly.
- Vane axial system with air straightener for increased efficiency.

Casing | Steel sheet, epoxy painted. Steel sheet, hot-dip galvanized. Guidance for specification option: On request; protects against atmospheric agents. |
Impeller | Die-cast aluminium. |
Accessories | Protection guard, flat (CCr). Guidance for specification option: Prevents casual contact with moving parts of the fan. Manufactured in steel rod and protected against atmospheric agents. For long case and short case on impeller side. Inlet / outlet cone (CCbo). Guidance for specification option: Turns the standard short case execution into a long case version, also at site, with impeller and motor completely protected inside the casing. Manufactured in steel sheet, with fixing flanges according to UNI ISO 6580 - EUROVENT standard. Support feet (CCst). Guidance for specification option: Suitable to fasten the fan on the floor or to the ceiling. Manufactured in steel sheet and protected against atmospheric agents by epoxy paint. Cylindrical silencer, without pod (CCsa). Guidance for specification option: Consult manufacturer for options and insert requirements. Cylindrical silencer, with pod (CCsb). Guidance for specification option: Consult manufacturer for options and insert requirements. Antivibration mounts. Flexible antivibration connector (CCga-HT). Guidance for specification option: Prevents the propagation of vibrations along the ducted system. Manufactured with two flanges in steel sheet, according to UNI ISO 6580 – EUROVENT standard for fixing to the fan and to the duct, and a strong flexible fabric joint. Suitable for high temperature working. Backdraught damper (BDD). Guidance for specification option: Allows the return of the flaps in closed position. They avoid heat dispersion when the fan is off and require a negligible opening pressure. Counter-flange (CCf). Guidance for specification option: Ring plate with holes according to UNI ISO 6580 – EUROVENT standard, compatible with fan flange. Used for easier connection between the CC fan and the duct. Counter-flange with collar (CCfc). Guidance for specification option: Counter flange with addition of 80 mm of round duct. Used for easier connection between the CC fan and the duct. Outlet terminal (CCot). Guidance for specification option: Outlet terminal with protection guard. None. |
