Fans of type VVF-112M
Fans such as VVF-112M is designed to blow computers, including microcomputers, test and measurement equipment, as well as individual units, appliances, radios, etc. When used in moderate and cold climate category UHL 4.2 GOCT 15150 -69.
Fan power from single-phase AC voltage of 220 V, 50 Hz.
Main technical characteristics:
Execution Fan weight, kg
The nominal value of the fan performance at a static pressure of zero, should be 2.3 m3/min.
The minimum value of fan capacity should be 2.07 m3/min.
The nominal value of the static pressure at a flow equal to zero, should be 4.6 kg/cm2.
The minimum value of the static pressure must be 4 kg/cm2.
Limit deviation of fan capacity upwards is unlimited.
Rated speed of the fan is to be 2720 r / min.
Nominal power consumption of the fan should be no more than 20 watts. Nominal input current fan has a life of 0.15 A.
The rated duty continuous S1 fan according to GOST 183-74.
The fan is operational at a deviation of voltage in the range from plus 10 to minus 15% from the nominal value and the frequency of 2.5% from the nominal values.
The fan is operable at maximum permissible ambient temperature of 55 ° C.
The fan is operational in a vibration frequency of 1 Hz to 55 Hz with an amplitude of 0.1 mm.
Probability of failure of the fan for a period of 3000 hours of use should be 0.85 at a confidence level P * = 0.8.
