WALL-MOUNTED FAN ВНР-ДУ

The fans ВНР-ДУ are installed directly on the wall of a building inside or outside the room and designed to remove high temperature smoke-air mixtures arising during a fire and simultaneously remove heat outside the room.

This ensures the localization of the fire zone and gives the opportunity to carry out firefighting operations and rescue people and equipment. The fans can move gas-air mixtures with temperatures up to 400 ° C and up to 600 °C for at least 120 minutes.

Wall-mounted radial fans with a vertical axis of rotation perform the exit of airflow from a smoke-filled room to the street. The fans have an impeller with backward-curved blades, a toroidal inlet with a large inlet diameter and a volute casing. The fans can be used in six different arrangements indoors and outdoors. When installed indoors, smoke-air mixture enters the fan directly from the smoke-filled room (arrangements 1 and 4) or from the air duct (arrangements 2, 5). In the latter case, an inlet box is installed at the fan inlet.

The fan can be operated at temperatures of the working medium from -40 ° С to +45 ° С.

The environment and air must not contain aggressive gases and vapors that destroy materials, paint coatings and electrical insulation of the product.

The fan is manufactured in climatic versions for operation in areas with moderate У (moderate) and УХЛ (boreal) climates and location categories 2 and 3 according to GOST 15150.
