CBZ-110A Marine Fan

Introduction:

CBZ series marine or navy explosion-proof axial fans are designed and manufactured according to GB11800-2008《marine explosion-proof axial fans》,GB3836.1-2000《electrical apparatus for explosive atmosphere》GB3836.2-2000《electrical apparatus for explosive atmospheres, and explosion-proof electrical equipment “ d “ 》,《Rules for Steel Sea Ship in Class and Building 》.

The series fans have been examined and proved up to standard by explosion-proof inspection authority of the PRC and have got the certificate of inspection. They have also been examined by the register of shipping of PRC and have got the certificate

Structure

There are five structural types: type Ⅰ(deck type), type Ⅱ(tube type), type Ⅲ(separate cabins type), type Ⅳ(olive type) and type Ⅴ(wind upward type). The construction is non-sparking.
Type Ⅰ explosion-proof fan has an explosion-proof motor installed on the top of the frame and a wire mesh guard with 2 inch, made of stainless steel, surrounding the frame. The fan is vertically fixed on the deck. It can be delivered for air supply or air extraction.
Type Ⅱ explosion-proof fan has no hood, built-in type anti-corrosive motor id mounted on the casting by vane. It can be installed vertically or horizontally, and also be installed on the deck. It can be delivered for air supply or air extraction.
