Consumed by the device fan VN-3 power must not exceed 26W.
Current consumption must not exceed 165mA.
Static pressure of fan unit VN-3 at zero performance should not be less than 50Pa, at a voltage of 220V ± 2V.
Performance at a static pressure equal to zero should not be less than 2.8 m 3 min, at a voltage of 220V ± 2V.
MTBF fan unit VN-3 shall be not less 25000ch.
The average storage time prior to commissioning shall not be less than 1 year.
Average life instrument fan VN-3 must be at least 10 years.
Operating temperature range - from -10 º C to +70 ° C.
Dielectric strength of the stator windings with respect to the housing must withstand without breakdown test voltage 1250V sine magnitude 60 V for 1minuty after holding the fan 48 hours at a relative humidity of 95% ± 3% and a temperature of 30 º C ± 3 ° C.
Overall dimensions fan VN-3 should be no more 130h130h40mm.
Weight should be no more than 0.65 kg;
a) fan VN-3 - 1 item;
b) Passport - 1 ekzemplyar;
Instructions for operation of the device fans VN-3:
The fan may be installed in the apparatus, to which he belongs, in any position;
The rotation of the impeller - counter-clockwise;
To meet the requirements for aerodynamic performance and noise level fan installed no closer than 30mm to the structural elements that create resistance to air flow in the bearings of noise;
It is strictly forbidden to expose the fan mechanical shock during testing, interdepartmental transport and installation of products;
Commissioning and measurements are carried out after extraction fan and shutter speed of at least 6 hours at 20 º C ± 10 ° C and humidity of 45% to 80%;
Before turning on the fan must be grounded, which connects the terminal copper wire at least 1 mm 2 with a ground bus;
Maintenance unit ventilators VN-3:
At least 1 time in half to be prevented fan, which includes the following:
-. Cleaning the dust shell and the rotor vane;
- Flushing of bearings;
- Lubrication of bearings;
To perform preventive maintenance is necessary, remove the cover, remove the lock washer, the washer, remove the rotor blades, remove the bearings, remove the nut and washer spring;
Dusting of the rotor with the impeller and the casing to produce a dry brush or vacuum cleaner. Permitted removal of dust from the rotor impeller and casing by blowing with compressed air, free of oil vapors;
Bearings to produce washing of the bath with oil;
After washing, drying to produce bearings;
After drying, the bearings are lubricated with grease. The assembly unit fan VN-3 in the reverse order to produce disassembly;
Maintenance works to make a mark in Schedule 2 to this passport to check the fan to meet the requirements of Section 2;
Instrument manufacturer's warranty fans VN-3:
The manufacturer guarantees that the fan requirements of this specification, subject to consumer environments, transportation and storage, established specifications;
The warranty period fan - 24 months from the date of commissioning;
Guaranteed shelf life fan in a package of conditions, but at a temperature of 1 ° to 40 ° C 6 months from the date of manufacture;
Enter the unit ventilators VN-3 into service during the warranty period of storage stops its course.If the device has not been put into operation before the expiry of warranty period of storage, the beginning of the warranty period is the time to expire Ia warranty period of storage;
Mark on putting into operation to produce products in Appendix 1 of this passport (stamped on the conduct of the input control is the date of commissioning);
Guarantees do not apply in the absence of a passport for a product, non-compliance with the conditions of operation, transportation, storage, and marks in the passport of the commissioning and maintenance of established specifications and present a passport;
