ATEX Plastic Fan and Ex-proof Plastic Fan Manufacturer

Antistatic, Special Design and High Performance Plastic Radial Fans 

ATEX plastic fan is a special industrial fan solution used in processes where explosive atmosphere is likely to occur and designed by evaluating the mechanical structure of the fan, material properties, electrostatic charging, grounding and other possible ignition sources.

As Efsan Machine plastic fan its production with a fan engineering approach we realize. Plastic fan not only as a ventilation equipment made of plastic material; flow rate, pressure, temperature, gas properties, rotor geometry, mechanical safety, sealing and process conditions a designed by evaluating together industrial radial fan we treat it as.

This approach is even more important in ATEX applications. Because just because the fan motor is ex-proof does not mean that the entire fan automatically meets ATEX requirements. Mechanical or electrostatic ignition sources that may occur in the fan itself should also be evaluated.

What is ATEX Plastic Fan?

ATEX plastic fan; Designed for use in hazardous areas where explosive gas, steam or fog atmospheres may be present it is a plastic radial or centrifugal fan.

It cannot be assumed that a standard plastic fan can be used in an ATEX environment. The following parameters should be evaluated together in fan selection and design:

• Zone class
• Gas group
• Temperature class
• Process temperature
• Chemical properties of gas or steam
• Debi
• Pressure
• Gas density
• Material properties
• Electrostatic charge
• Grounding
• Mechanical operating conditions between rotor and body
• Sealing requirements

Therefore, an ATEX plastic fan is not a product obtained by simply adding an ex-proof motor on top of a standard plastic fan. The entire fan must be evaluated according to the operating conditions of the process.

Why Is Ex-Proof Motor Alone Not Enough?

In a system using an ex-proof motor does not mean that the entire fan is ATEX compatible.

In ATEX application, fan body, rotor, shaft, connections, material properties, electrostatic charging, grounding and mechanical working conditions should be evaluated together.

Especially in plastic fans, electrostatic charging is an important design issue. Electrostatic charge may occur on plastic surfaces due to process flow, particles, droplets or other operating conditions.

That’s why ATEX is in plastic fan design:

• Selection of antistatic or conductive materials
• Grounding
• Rotor and body design
• Preventing mechanical friction
• Assessment of possible sources of ignition

considered together.

Efsan Machinery’s approach is not only to choose an ex-proof motor, but to evaluate the entire fan in terms of process and ATEX requirements.

Antistatic Plastic Fan Design

Antistatic plastic fanis a fan designed with a suitable material and construction approach to control electrostatic charge in applications with explosive atmosphere.

In these applications, not only the surface properties of the fan are evaluated, but also the entire material and construction.

Efsan Machinery in plastic fan applications, when required by the process Antistatic material options such as PP-EL and PP-EL-S can evaluate.

Antistatic structure;

material + construction + grounding + process conditions

it is evaluated by considering them together.

Zone 1 and Zone 2 ATEX Plastic Fan

ATEX fan selection Zone 1 and Zone 2 its distinction is one of the basic parameters.

Zone 1, refers to areas where an explosive atmosphere of gas, steam or fog may occasionally form during normal operation.

Zone 2 on the other hand, it refers to areas where explosive atmosphere is not expected to occur during normal operation, and if it occurs, it is expected to be short-term.

However, an ATEX plastic fan is not selected based solely on the Zone number. Gas assembly, temperature class, process temperature, gas characteristics and actual operating conditions of the equipment it should also be evaluated.

Therefore, in Zone 1 or Zone 2 applications, the design of the fan must be made based on the relevant process and equipment requirements.

High Pressure and High Flow ATEX Plastic Fan

Efsan Machinery is not only plastic fans for standard ventilation applications specially designed plastic radial fans with high pressure and high flow rate it also produces.

The performance of a plastic fan is not determined solely by fan diameter or motor power.

Actual operating point;

flow rate + pressure + temperature + gas characteristics + density + speed + system resistance

it is determined by evaluating together.

Application specific instead of standard molded fan geometries in corrosive and hazardous processes requiring high pressure or high flow rate:

• Rotor geometry
• Fan body
• Shaft and connection details
• Material selection
• Sealing solution

designable.

This approach in particular high pressure plastic fan, the high flow rate plastic fan and it is important in special process fan applications.

ATEX Acid Fan and Plastic Fan for Corrosive Gases

In addition to the ATEX requirement, plastic fans can be an important solution in processes requiring high corrosion resistance.

Acid fan and in corrosive gas fan applications, suitable materials and construction are evaluated for the following fluids and process gases:

• HCl
• H₂SO₄
• HNO₃
• HF
• Cl₂
• NH₃
• SO₂
• H₂S
• Acid gases
• Acid vapors
• Corrosive gases
• Chemical vapors
• Toxic process gases

However, the fan material is not determined solely by the name of the chemical.

Concentration, temperature, gas composition, flow rate and pressure it creates real working conditions and is evaluated together in material selection.

Therefore, a general approach such as “a single plastic is suitable for all acids” is not correct.

Plastic Fan Material Selection

Different plastic and composite material options can be evaluated according to process conditions.

Among them:

• PP
• PP-EL
• PP-EL-S
• PVC
• PVDF
• FRP / fiberglass

materials such as can be found.

However, material selection is not made solely based on chemical resistance. Mechanical strength, temperature, pressure, gas composition, operating time and ATEX requirements of the fan should also be taken into account.

It is not right to use the same plastic material for every process.

Instead of plastic in some applications FRP or fiberglass fan the solution may be more appropriate. The aim here is not to apply a certain material to every application, but to suit the operating conditions of the fan to determine materials and construction.

Sealing in ATEX Plastic Fans

In systems where chemical gas, acid vapor or hazardous process gases are transported sealing is one of the important parameters of fan design.

Especially:

• HCl and other acid gases
• Chemical vapors
• Corrosive gases
• Toxic gases
• Scrubber outlets
• Ex-proof processes

fan body connections and shaft passages should be carefully evaluated.

Construction is developed in Efsan Makina plastic fans according to the sealing level required by the process.

When necessary:

• Special shaft sealing
• Additional sealing elements
• Special body connections
• Connection details in accordance with process conditions
• Plastic valve solutions suitable for PP valve and process circuit

evaluable.

Sealing is therefore not a standard product feature a fan parameter designed according to the process requirement it is treated as.

Plastic Air Clamp and PP Valve Solutions

In ATEX and corrosive gas systems, the fan should not be evaluated alone.

Depending on the need of the process plastic air valve, PP valve and other plastic process equipment it can also be evaluated together with the fan system.

These equipment;

• Chemical suction lines
• Scrubber systems
• Acid gas lines
• Corrosive air ducts
• Wastewater and treatment plants
• Chemical processes

it can be used in applications such as.

Where is ATEX Plastic Fan Used?

ATEX plastic fans, in processes where the risk of explosive atmosphere and corrosion resistance are important at the same time available.

Major applications:

• Chemical plants
• Petrochemical plants
• Acid processes
• Pickling / pickling lines
• Galvanizing plants
• Scrubber systems
• Wastewater treatment plants
• Industrial treatment plants
• Battery and battery production facilities
• Paint and coating facilities
• Pharmaceutical and chemical processes
• Chemical storage areas
• Processes with flammable gas
• Hazardous process gas suction systems
• Corrosive gas and chemical vapor absorption systems

Especially ATEX plastic fan, ex-proof plastic fan, antistatic plastic fan and corrosive gas fan in applications where the need is in the same system, it becomes important to design the fan on a process basis.

Efsan Machinery ATEX Plastic Fan Production Approach

Efsan Machine; ATEX plastic fan, ex-proof plastic fan, antistatic plastic fan, high pressure plastic fan, high flow rate plastic fan and specially designed plastic radial fan develops solutions.

The basic approach here is to consider plastic material as a production material only it is to evaluate as part of fan engineering.

In a plastic fan design:

Process → flow rate → pressure → temperature → gas properties → material → rotor → mechanical safety → sealing → ATEX requirements

evaluated together.

Thanks to this approach, instead of a standard plastic fan, it is suitable for the actual working conditions of the process special design industrial radial fan developable.

Plastic material expertise and fan engineering are not the same thing.

Efsan Machinery carries out plastic fan production with an industrial fan design, rotor production, balancing, mechanical safety, performance and process engineering approach.
