Description
The increased pressure comes from the guide vane assembly: the guide vanes behind the impeller convert the swirl of the airflow into static pressure. The casing is tubular thick sheet steel, the motor support is welded to the casing, the impeller is cast aluminum, the airflow goes from the impeller to the motor, and the electrical connection is made in an external terminal box. The surface is protected with primer and paint for corrosive environments, and on request the casing is made fully stainless or hot-dip galvanized. The class F motors run on ball bearings, IP55, with a three-phase supply of 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW. The ambient temperature is up to +70 °C, and the datasheet states a range of −20…+70 °C.
How to choose
Sizes range from 50 to 125 with 2-pole and 4-pole versions, and the code 125 hp corresponds to a 90 kW motor. For mining work the manufacturer separately names single-stage fans with a pressure of up to 3000 Pa and multi-stage fans with a total pressure of up to 5000 Pa and a diameter of 315–1800 mm, and HTP belongs to the same class of equipment. Explosion-proof ATEX motors and two-speed motors are available on request. The series is used for ventilation of mines, ore mines and underground workings, construction of tunnels and metro, and systems with long ducts.

FAQ
Why does HTP need guide vanes?
The guide vanes behind the impeller convert the swirl of the airflow into static pressure. In this way the fan overcomes large pressure losses in long pipelines.
What ambient temperature is permitted?
Up to +70 °C. The datasheet states a range of −20…+70 °C, and the specification also gives a lower limit of −25 °C, so it is clarified when ordering.
What are the power and impeller diameter of HTP?
Sizes 50–125 with an impeller diameter of 500–1250 mm, motors by model code 1.1–90 kW, with 2-pole and 4-pole versions.
Can a stainless casing be ordered?
Yes, on request the fan is made entirely of stainless steel or with hot-dip galvanizing.
In which direction does the airflow go?
From the impeller to the motor. The electrical connection is made in an external terminal box.
