VETRAN

The valves are designed for automatic overlap (opening) of openings in building envelopes, for overlap (opening) of technological openings and openings in places where ventilation ducts pass through interfloor ceilings, walls, partitions, for overlap of openings in enclosing structures of supply and exhaust ducts of smoke, general exchange ventilation , local suction and air conditioning.

Axial fans of the VOK series are used in exhaust ventilation systems of industrial and public buildings, in emergency smoke ventilation systems as back-pressure fans. The fans are designed to move air or other non-explosive, non-aggressive gas mixtures with temperatures up to +40 ° C, free of sticky substances and fibrous materials, with a concentration of dust and other solid impurities not exceeding 100 mg / m³.

Radial fans of VRK.G type are used in exhaust ventilation systems of industrial and public buildings. General-exchange fans are designed to move air or other non-explosive, non-aggressive gas mixtures with temperatures up to plus 70 ˚С, free of sticky substances and fibrous materials, with a concentration of dust and other solid impurities not exceeding 100 mg / m³. VRK.G fans are also presented in corrosion-resistant and explosion-proof versions.

Radial fans of VR.80 -75 type are used in supply and exhaust ventilation systems of industrial and public buildings. Designed to move air or other non-explosive, non-aggressive gas mixtures with temperatures up to +70 ° C, free of sticky substances and fibrous materials, with a concentration of dust and other solid impurities not exceeding 100 mg / m³. Also fans VR.80-75 are presented in explosion-proof and corrosion-resistant versions.

Radial smoke exhaust fans of VRD.80-75 type are designed to remove high-temperature smoke-air mixtures arising during a fire and simultaneously remove heat outside the serviced room. The fan is used in exhaust (emergency) ventilation systems of industrial, public, residential, administrative and other premises (except for categories A and B of explosion hazard according to NPB 105-03) to remove smoke-air mixtures formed during a fire with a temperature of up to +400 ° C or up to + 600 ° C for 120 minutes. It is possible to use fans in general ventilation systems of industrial, public, residential, administrative and other premises for moving air or other non-explosive, non-aggressive gas mixtures with temperatures up to + 70 ° C, free of sticky substances and fibrous materials, with a concentration of dust and other solid impurities no more than 100 mg / m³, with reduced rotation frequency no more than 50%.

Rectangular duct fans (VKT) are used in supply and exhaust ventilation systems for industrial and public buildings. The fans are designed to move air or other non-explosive, non-aggressive gas mixtures with temperatures up to +40 ° C, free of sticky substances and fibrous materials, with a concentration of dust and other solid impurities not exceeding 100 mg / m³. Climatic modification of fans U2 in accordance with GOST 15150-69 (ambient temperature from -30 ° C to +40 ° C). In the place where the fans are installed, the root mean square value of the vibration velocity from external sources of vibration should not exceed 2 mm / s. The degree of protection provided by the sheath is IP44.
