Ventilators EVI are applied to ventilation, heating and conditioning systems in cabs 

and cabins of trucks and tractor machinery and other vehicles. There are 2 types ofventilators – EVI 12 and EVI 24 -hich differ in nominal supply voltage 12V and 24 V.

 Technical characteristics:

1.         Rotor rotation frequency, turns/min:

EVI 12        stage 1       1900±500

                  stage 2       4100±600

EVI 24        stage 1       1900±300

                  stage 2       3300±300

                  stage 3       4500±300

2.         Current consumption, À, not more than:

EVI 12         20,0

EVI 24         10,0

3.         Nominal output, m3/h:

EVI 12        stage 1       155

                  stage 2       490

EVI 24        stage 1       180

                  stage 2       396

                  stage 3       576

The design represents a paired centrifugal ventilator with a drive from one engine with shaft lead to two sides. The case of the ventilator and the rotor is plastic, foundation is metal.

The ventilator is connected to vehicle’s electrical system with the help of the connector of a special harness.

The ventilator drive is made on the basis of import collector engine with an additional resistor for a phased change of rotation frequency.

The ventilators are applied to tractors produced by Minsk Tractor Works, trucks MAZ, machinery of “Amkodor” works (Minsk) and trolley-buses produced by «Belkomunmash» (Minsk).
