Navy Explosion Proof Axial Flow Fan

Navy Explosion Proof Axial Flow Fan


An explosion-proof axial flow fan is a type of industrial fan designed to operate in hazardous environments where explosive gases, dust, or other combustible materials may be present. These fans are typically used in industries such as oil and gas, petrochemical, mining, and chemical processing, where safety is a primary concern.

The design of an explosion-proof axial flow fan includes features that prevent sparks or other sources of ignition from occurring within the fan or in the environment surrounding it. The fan housing is constructed from materials that are non-sparking and able to withstand an explosion without rupturing. The electrical components are also designed to prevent sparking, and the wiring is contained within conduit or armored cable.

Explosion-proof axial flow fans are available in various sizes and configurations to meet the specific requirements of different applications. They are typically used for ventilation, exhaust, or air circulation in hazardous areas, and can be mounted in a variety of orientations, such as ceiling, wall, or floor-mounted. They are also often designed to operate at high temperatures or in harsh environmental conditions, such as corrosive or abrasive atmospheres.

In summary, an explosion-proof axial flow fan is a specialized industrial fan designed to provide ventilation or air circulation in hazardous environments, such as those found in the oil and gas, petrochemical, and chemical processing industries. Its design includes features that prevent sparks or other sources of ignition from occurring and it must be certified to meet specific industry standards for explosion-proof equipment.

Configuration selection:

Part name

Texture of material

Advantages / disadvantages


Carbon steel

After heat treatment, higher hardness and better wear resistance can be obtained. The hardness in the annealed state is very moderate, and it also has good machinability. Raw materials are very common, easy to obtain, and the production cost is relatively low


Aluminium alloy

Low density, high strength, good conductivity, good corrosion resistance and easy processing

Electric machinery

Finished marine motor with low noise, low vibration and high protection grade

Junction box


It has good plasticity and welding performance, good forming ability, and has a certain strength. It is suitable for engineering structures. It has good practical performance, relatively cheap price and high cost performance

Stationary blade support foot


Ordinary carbon structural steel has simple production process, good process performance (such as welding performance, pressure processing performance, etc.), necessary toughness, good plasticity, low price and easy to supply in large quantities. It is usually used after hot rolling

Casing flange


Good toughness and plasticity, certain elongation, good welding performance and hot workability

Incorrect model selection and differences

The air volume and pressure cannot meet the customer's requirements

The air volume and pressure cannot meet the customer's requirements

The air volume and pressure meet the requirements, and the operation is stable and safe

Use inferior materials and turn out substandard goods

The casing is easy to rust

Adopt marine standard carbon steel

Impeller not durable

It is easy to be corroded by seawater in a short time, resulting in air holes in the impeller and reduced air volume

Adopt Marine Standard 104 aluminum alloy

More corrosion resistance and longer service life

Choose ordinary motor as marine motor

The insulation grade cannot meet the requirements

Strictly select marine motor

The shell has higher protection grade, certain explosion-proof property, more moisture and corrosion resistance, and longer service life

The explosion-proof grade is not selected as required

The motor fails to meet the explosion-proof requirements and is prone to danger

Choose explosion-proof grade in strict accordance with application requirements
