Delivering Best-in-Class Performance and Low Cost of Ownership

The 100X is a highly accurate, flexible test rig for a wide range of filter media types designed to optimize production yields while delivering the lowest cost of ownership.

100% Sampling Aerosol Detection System

The 100% Sampling Aerosol Detection System is capable of testing a wide range of HEPA and ULPA filters, up to 99.9995% efficiency. Its innovative design provides a single source of truth, reduces potential sampling errors inherent in legacy designs and with fewer, more robust parts, reduces serviceability costs while increasing equipment uptime.

Best-in-Class Differential Pressure Management Accuracy

The 100X can be configured with your choice of four differential pressure measurement ranges, providing highly accurate, repeatable results that minimize false failures, while increasing both production yields and confidence in the test results.

Automatic, Hybrid & Manual Configurations

The 100X can be configured at time of order to operate three ways:

  • A Manual version is ideal for lab use or production lot testing that requires the operator to initiate the test using ergonomic photoelectric actuators. A test fixture for 100 cm2 flat sheet media is included.
  • The Automatic version integrates seamlessly with a customer designed, PLC-driven, automated production line and is ideal for 100% in-line non-destructive product testing. The unit is controlled via communication ports and becomes a client device to the automated production line.
  • The Hybrid version provides the versatility to operate in Manual mode using the local test fixture or can be switched to Automatic mode using a remote fixture in an automated production environment.

Wide Range of Aerosol Flow Rates

The 100X is capable of air flow rates between 10-170 liters per minute, providing flexibility to test a wide range of filter types. Integrated flow controller keeps flow rates constant leading to more accurate results.

Oil or Salt Aerosol Generation

The 100X is available in either an Oil (DOP, PAO, Paraffin) or Salt (NaCl) aerosol generation models. The patented Aerosol Solution Replenishment System is a separate 2-liter reservoir tank that increases productivity by eliminating the need to shut down production to refill the generator. For salt-based test systems, the replenishment system mitigates aerosol concentration and size / distribution shifts due to dynamic salinity.

Other Features include:

  • LCD touch screen user interface
  • USB; RS232; PLC-Controls (for Automatic, Hybrid version)
  • Compartmentalized design, with easy access for filter replacement and serviceability

Testing N95 Respirators for Efficiency

N95 respirators are widely used by workers across healthcare, construction, and many other industries. The National Institute for Occupational Safety and Health (NIOSH) is the agency that tests and certifies all models of N95 respirators.

See how fast and easy N95 respirators are tested for efficiency with the 100X Automated Filter Tester.


The 100X can be supplied with an optional local exhaust module to filter all aerosol exhaust when facility exhaust ducting is not available. The local exhaust module is designed with a convenient differential pressure gauge to help determine when to replace the internal HEPA filter. To extend the life of the HEPA filter, turn the 100X off or place it in standby mode when not in use. NOTE: the local exhaust is designed for use in manual mode.

  • Reliable local exhaust module, ideal when facility exhaust is not available
  • Convenient differential pressure gauge to help determine when to replace the internal HEPA filter

A large base cabinet, convenient for storing manuals and tools is available as an option. The cabinet is equipped with heavy duty locking swivel casters enabling the 100X to be easily moved wherever you need it.

  • Large 71 cm L x 69 cm W x 76 cm H (27 in x 28 in 30 in) cabinet convenient for storing manuals and tools
  • Large 12.7 cm (5 in) heavy duty locking swivel casters for portability and stability
