Product description

An ATEX filter integrity tester is designed for verifying membrane filter integrity in environments where explosive atmospheres may be present. The system enables standard membrane integrity tests to be performed safely in hazardous industrial areas.

Technical overview

Filtration processes involving solvents, alcohols or volatile chemicals are often operated in classified ATEX zones. In these environments, testing equipment must comply with explosion protection requirements. An ATEX filter integrity tester allows verification of membrane filter performance while meeting safety requirements for operation in hazardous areas. The device performs the same integrity test procedures used for membrane filtration validation in pharmaceutical and industrial filtration systems.

Operating principle

The tester applies controlled gas pressure to a wetted membrane filter and measures the resulting gas flow or pressure behaviour. Typical integrity test methods include:
  • Forward flow / diffusion testing
  • Bubble point testing
  • Pressure hold testing
  • Water intrusion testing for hydrophobic membranes
Measured values are compared with expected integrity limits to determine whether the filter element is intact and performing according to specification.

Material options

ATEX integrity testers are constructed using components suitable for operation in hazardous environments. Typical materials include:
  • Explosion-protected instrumentation
  • Industrial stainless steel housing
  • Certified pressure sensors
  • Chemically resistant tubing and connectors
All components are selected to comply with relevant explosion protection standards.

Available micron ratings

Integrity testing instruments verify membrane filters across a wide range of filtration ratings rather than performing filtration directly. Typical membrane filters tested include:
  • 0.1 µm sterilizing grade membranes
  • 0.2 µm sterile filtration membranes
  • 0.45 µm clarification membranes
  • Other microfiltration membranes depending on process requirements
The tester confirms whether the installed filter meets the expected integrity parameters associated with its specified retention rating.

Design and construction

ATEX filter integrity testers are engineered for safe operation in hazardous industrial environments. Typical system features include:
  • Explosion-protected electrical or pneumatic components
  • Pressure control and measurement systems
  • Interfaces for connection to cartridge filter housings
  • Data recording and test documentation capability
  • Compatibility with standard membrane integrity test methods
The system design ensures reliable measurement while complying with explosion protection requirements.

Typical applications

ATEX filter integrity testers are commonly used in:
  • Chemical processing plants
  • Pharmaceutical solvent filtration processes
  • Alcohol and beverage production facilities
  • Industrial filtration systems operating in ATEX zones
  • High-purity chemical filtration

Key benefits

  • Integrity testing capability in hazardous environments
  • Compliance with ATEX explosion protection requirements
  • Supports multiple membrane integrity test methods
  • Suitable for filtration systems handling volatile liquids
  • Compatible with cartridge and membrane filter systems

Configuration and quotation

To configure an ATEX filter integrity tester, the following parameters should be specified:
  • ATEX zone classification
  • Required pressure range
  • Filter type and membrane material
  • Connection interface to the filter housing
  • Required documentation or validation features
  • Environmental conditions at the installation site
Providing these parameters allows the tester configuration to be matched to the filtration system and installation environment.

Technical support and validation

Selecting the correct filtration solution often requires verification under real process conditions. Filtra International supports this process through several practical testing and validation options.

Filter samples – available for compatibility and performance checks in existing filter housings.
Full-scale filter housing rental – for temporary installations or process evaluation.
Laboratory and pilot-scale filtration units – enabling controlled testing before full implementation.
Application testing by our team – customers may send product samples for filtration trials and performance evaluation.

These options allow process validation before committing to a permanent installation.
