Potentially explosive atmospheres, also known as hazardous areas, are zones in which an explosion can occur due to the presence of flammable gases, vapors or dusts. In such areas, all devices and installations used must comply with special safety requirements to minimize the risk of ignition of ignition sources. Filters used in such environments play an important role, especially in air purification and dust protection

Requirements for filters in potentially explosive atmospheres

Filters used in potentially explosive atmospheres must meet certain requirements to ensure safety. These requirements include

• Ignition protection: Filters must be designed so that they are not a source of ignition for explosive atmospheres. This means that no sparking or excessive heating may occur during operation.
• Certification: Devices and filters used in hazardous areas must be certified in accordance with the applicable standards and regulations, e.g. in accordance with the ATEX Directive (ATEX 2014/34/EU) in the European Union or the NEC 500 in the USA.
• Suitable materials: The materials from which filters are made must be resistant to corrosion and other chemical attacks. Special antistatic materials are often required for filter use in potentially explosive atmospheres.
• Pressure resistance: Filters must be designed to withstand the potential overpressure or underpressure of air in potentially explosive atmospheres.
