YFB4 dust explosion-proof induction motor

CATALOGUE OVERVIEW

About this motor series

Wannan YFB4 is a three-phase induction motor family intended for combustible-dust environments. The manufacturer publishes a 0.12–315 kW range, S1 duty, class F insulation and IE4 efficiency classification. Listed applications include grain processing, textiles and chemical processing.

Hazardous-area suitability must be checked against the exact motor certificate and nameplate. Specify dust group, zone, surface-temperature limit and ambient conditions, then request the current certificate for the destination market. This catalogue listing does not establish ATEX or IECEx approval.

Selection priorities for Explosion-proof motors

Dust and gas protection are different. Confirm zone or division, substance group, temperature classification and the certificate scope with qualified project personnel.

• Gas or dust environment
• Site classification
• Certificate and exact marking
• Temperature and ambient range
• Installation requirements

Use the YFB4 reference when requesting a datasheet from Wannan Motor. Confirm these requirements against the exact offered model before comparing quotations.
