content1. Preface
CBL series explosion-proof centrifugal fans for marine use are
designed and manufactured according to GB 11799-89(Marine
Explosion-proof 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.
