IIC Hydrogen Fan
An ATEX certified fan from Woodcock & Wilson Ltd will give you confidence that the fan supplied has been assessed by an approved notification body.
This certifications ensures the fan is safe, manufactured to the strictest European standards, and designed to meet the specific type of explosive or hazardous environment that it is intended to operate in, whilst also reducing the need and cost of additional testing.
What is an IIC Fan?
An IIC fan is a type of ventilation fan specifically designed to operate in environments where hydrogen gas is present. Hydrogen is highly flammable and requires specially designed equipment to ensure safe operation. IIC fans are engineered to prevent ignition sources, reducing the risk of explosion in hazardous areas.

What is an IIC Fan?
IIC fans are used in various applications where hydrogen gas might be present, including:
Wind turbines with energy storage systems to store surplus energy.
Hydrogen generation and fuel cell systems.
Hydrogen filling stations.
Hydrogen distribution and storage plants.
Battery rooms for backup and uninterruptible power supplies.
Certification Standards for IIC Fans
While other manufacturers may offer IIB + Hydrogen, Woodcock and Wilson are able to offer independently certified IIC (Hydrogen) fans. These fans can be ATEX certified, UKEX certified & IECEx certified or all three.
The certification covers:
EN14986: Design of fans working in potentially explosive atmospheres.
EN80079-36: Non-electrical equipment for explosive atmospheres. Basic method and requirements.
EN80079-37: Non-electrical equipment for explosive atmospheres. Non-electrical type of protection (constructional safety "c", control of ignition sources "b", liquid immersion "k").
The implementation of the EN ISO 80079 standard series in 2016 for None- Electrical Equipment
Marking
Markings for None- Electrical Equipment follows the same methodologies as for electrical equipment including all provided protections
| Type of Protection | Ex Code | Zone | ISO/IEC & En Standards |
|---|---|---|---|
| General Requirements | h | 1, 2, 21, 22 | 80079-36 |
| Construction safety | h | 1, 2, 21, 22 | 80079-37 |
Ignition prevention is NOT only for electrical equipment.
It’s crucial to understand that both mechanical and electrical parts of fans must be certified to ensure complete safety. Customers can sometimes be misled into believing that Ex equipment only needs to be self-certified for mechanical requirements and fully certified for electrical parts. This is not the case, as fans have both electrical and mechanical elements that must be fully certified to the correct standards.
Ensuring that your IIC fan is properly certified for both electrical and mechanical components is essential for safety and compliance.
