Marine Water Driven Explosion Proof Fan

Marine Water Driven Explosion Proof Fan

1. General
Marine Water Driven Explosion Proof Fan with water driven have high-hazard classfication, sound anti-wobble, anti-vibration and anti-impact performance. The fan of simple structure. Low weight, simplicity of operation as well as its port-ability(normally only one operator of required). Driven directly by fire protection water, this ventilator depends on on other power with sealed bearings, it largely reduced the maintenance job. With a wide applicability, this type of ventilator can work at ﹣35℃-250℃, ideal for ducting flammable and explosive gases or steam as well as poisonous or other harmful gases.

2. Configuration Options

Name of Parts	Material	Advantages/Disadvantages
Water turbine	copper alloy	Corrosion resistance, copper alloys are highly resistant to atmospheric and water corrosion. Copper is a diamagnetic substance. Good processability Good plasticity, easy to cold and hot forming; cast copper alloy has good casting properties.
Shell	Austenitic stainless steel	Austenitic stainless steel has good cold workability and good toughness and plasticity, but the strength is low, and the strength can only be improved by cold working or precipitation of intermetallic compounds.
Impeller	Aluminum alloy	Strong plasticity, light weight and high strength. Aluminum alloy profiles have strong air tightness, water tightness, heat insulation and sound insulation. Corrosion resistant and long service life.

3. Specific Difference Between Us and Other Suppliers

Comparison
Product Picture of other low quality supplier		Product Picture of our factory
Other low quality supplier	Consequence	Our Factory	Result
The thickness of the chassis steel plate is thin.	Easy to deform and directly affect the service life	Use steel plates with national standard thickness	The thickness of the steel plate is standard, and the product can be used for a longer time.
Chassis material cut corners	The case is easy to rust	Made of marine standard carbon steel	The product is corrosion-resistant and lasts longer
Impeller jerry-built	It will be easily corroded by seawater in a short time, resulting in pores in the impeller and reduced air volume	Adopt marine standard 104 aluminum alloy	More corrosion resistant, longer service life

4. Structure
Marine Water Driven Explosion Proof Fan is composed of water turbine, frame, casting, rotor, impeller, etc. The water turbine is precisely cast of anti-corrosion copper alloy, the casting is soldered of austenitic stainless steel and the impeller is cast of high strength aluminum alloy, with the whole structure of no-spark design.
