1. Preface

CBL series explosion-proof axial centrifugal fans for marine use are designed and manufactured according to GB 11799-89(Marine Explosion-proof Axial Centrifugal Fans), and general description and explosion-proof electrical equipment “d” of GB3836-83 《Electrical apparatus for explosive atom-spheres》  and 《Regulations for the Construction and classification of Sea-going steel ships》.

2. Application

      They can be delivered for gas mixtures or vapour containing combustibles and explosives, for ordinary air, for sea air containing salt fog, for air containing oil fog and other corrupt air supply or extracition.

Theses explosion-proof fan series are best suited to pumping out gas mixtures or vapour containing combustibles and explosives in oil cabins holds, pump-rooms, battery cabins, ammunition cabins, hangars, paint houses, etc . They can also be used for ventilation of other compartments of shipping and corresponding place of land's.

AC 50HZ, 380V or 60HZ,440V type YB-H (

Explosion-insular) or type Y-H (ordinary) three-phase asynchronous motors for marine use may be mounted on these fans
