Description
Roof fans (with horizontal emission) VKR
Advantages
- Installation of roof fans allows to save the useful area of the building on a roof. Cases of fans are manufactured with use of a polymeric covering.
- Built-in protection of electric motors.
- Protection against hit of rainfall to the ventilating canal.
Application
The Fans Roof Radial (FRR) are used in exhaust systems of ventilation and are installed on roofs of industrial and public buildings. Can work both in a ventilating network, and without it. Are intended for movement of inexplosivethe gas environments with a temperature not above 80 °C containing solid impurity no more than 0,1 g/m3 which are not containing sticky substances and fibrous materials.
Scope and restrictions of service conditions for roof radial fans of special execution see in the table, the section "General Information".
Service conditions
Ambient temperature from minus °C to plus 40 °C.
In the conditions of a temperate climate, 1st category of placement, in accordance with GOST 15150-69.
Design
Fans roof represent radial fans of low pressure, unilateral absorption, with working shovels, recurved.The case of the fan is manufactured of carbonaceous steel with a high-quality polymeric covering. The deflector around the fan case reliably protects from hit of rainfall to the ventilating canal. The drive — the three-phase asynchronous electric motor of the ACORUS series (AIM — for fans of explosion-proof execution). For protection against an overheat fans of the VKR series are supplied with the built-in thermal sensors with conclusions for connection of the device of protection of the engine.
IN ACCORDANCE WITH GOST 24814-81. Are made on TU 4861-021-15185548-04.
Production options:
General purpose — from carbonaceous steel.
Explosion-proof — from diverse B1 metals.
Warranty period of operation — 18 months.
