Roof Ventilators VK12 and VK24 (TS RB 500135046,009-2003) are meant for ventilating cabs and cabins of vehicles used in general environmental conditions. Climatic performance and position category is Î1 according to State Standard 15150.
Roof ventilators are meant for ventilating cabins of buses produced by Minsk Automobile Works, Pavlovsky Bus Works, Volzhsky Bus Enterprise “Volzhanin” and other. There are two types of ventilators: VK12-IK and VK24-IK, which differ in nominal supply voltage 12V and 24 V respectively. There are several variants of ventilator packaging arrangements depending on presence or absence of array and (or) damper:
