Brief introduction

FZB series flameproof fan (hereinafter referred as flame-Proof fan ) is a new forced cooling fan,designed specially for explosion-proof YVP motor which manufactured accordings to standard Q/320206JPQD01 -2012:(Axial fan of frequency variable motor),at the same time,this product obtained the National utility model patent,patent num-ber:ZL2006 2 0175243.X and conformd to China National Standards:GB3836.1 -2010 Electrical Apparatus for Explosive Gas Atmospheres Part 1:General Requirements and GB3836.2-2010 Electrical Apparatus for Explosive Gas Atmospheres Part 2: Flameproof Enclosure"d",explosion protection marks is"Exd II BT4"
In 2009,Mingtong got the production license for the Explosion-proof electrical apparatus,license number:XK06-014-00721.

Construction

FZB series flameproof fan will provide a strong cooling effect on motors surface even motor running with a low speed.
Thanks to full enclosed ball bearing,Fan，s protection class reaches IP55.
Inside and outside the terminal box with grounded sign & lead terminal.
Insulation Class :F Temperature rise：B Class

Description

Description of explosion-proof mark

Operating limits

Rated voltage : 380V( ± 5%)
Rated frequency :50Hz
Max altitude : 1000M
Relative humidity: 85%(25°C)
Ambient temperature: -15°C 〜+40°C

Maintenance

Power supply : independent
Make sure the rotating direction as the same as fan direction arrow
Use heat-resistant silicone rubber four-core cable (minimum sectional area is 1.5mm²，its rated voltage must suitable for fan’s rated voltage) , four single-core cables are unacceptable .
power lead’s diameter conforms to rubber seals’s innener hole or smaller.
Tightening screws, grounded termianl box strongly and without dust or miscellany in the box.
Painting fan with Iron oxide red alkyd primer commonly ,Explosion proof mark"Exd II BT4wshould be use red enamel Fans should be stored in a clean,cool place free from acid and alkali fumes ,and the temperature is -10°C 〜+35°C、Relative humidity ≤70%.After a long time transportation or store,Check the insulation resistance of winding and shell which is not less than 2MΩ before installation.

The warranty period

Within two years from delivery date, Mingtong will replace or repair the problem fan for free ( damage caused by incorrect operation can，t be acceptable )
