Description
The tubular sheet steel casing has a polyester anti-corrosion coating, the impeller is cast aluminum with adjustable blade pitch, the airflow goes from the motor to the impeller, and the power cable is shielded with EMC protection. The casing support and flange make it possible to fix the fan on a wall. The hatch is made of an extruded aluminum profile with a thermal break, the heat transfer of the assembly is below 0.89 W/(m²·K), and sound insulation is Rw = 27 dB to UNE-EN ISO 10140-2. The construction is watertight, with open/closed position indicators, versions with top and bottom opening, and manual opening. The class H motors are rated for duties S1 and S2, have ball bearings, IP55 protection, IE3 class and one or two speeds, with 2-pole, 4-pole and 6-pole versions. The airflow in the table reaches about 131 000 m³/h. In daily mode the fan works for general ventilation.
How to choose
THT/WALL-F is intended for smoke extraction from cold rooms, where the thermal insulation of the enclosure and the absence of cold losses matter. THT/WALL/IE5 has an IE5 motor and 400 °C/2 h certification. For systems without smoke extraction requirements there are the WALL/AXIAL, WALL/FREE and WALL/DUCT series. Starting is done from the fire alarm system, which is not included in the delivery set.
