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

The 100X is a highly accurate and 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. The 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.

Most Accurate Pressure Management Available

The 100X can be configured with pressure transducers specific to your needs, 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 and requires an operator to engage a test using ergonomic photo-electric actuators. Included is a manual test fixture and standard 100cm2 flat sheet media fixture.
  • 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 become an Automatic version in the automated production environment.

100x Communication Options

# Name Description
1 Accessories Data Port RJ-45 Connection provides a communication interface for ATI designed accessories.
2 Accessories Power Port 4-pin circular connector with bayonet lock provides a dedicated 24VDC power supply for ATI designed accessories such as the Local Exhaust Module.
3 USB Port Provides serial data acquisition capability.
4 PLC Control External Start – Used to start an instantaneous test; Ready – Indicates that the unit is ready to start a new test; Pass – Indicates a passed test; Fail – Indicates a failed test; Fault – Indicates a non calibrated state for the system when coupled with the Cal Mode status indicator or a fault; Cal Mode – Indicates when a calibration routine is taking place.
5 Auto Port

Wide Range of Aerosol Flow Rates

The 100X is capable of best-in-class air flows between 5-120 liters per minute (and up to 180 liters per minutes with the high-flow 100Xp oil aerosol model), providing a highly flexible test that can test a wide range of filter resistance types.

Oil or Salt Aerosol Generation

The 100X is available in either an Oil (DOP, PAO) or Salt (NaCl) aerosol generation models. The patented Aerosol Solution Replenishment System is a separate 4-liter reservoir tank that increases productivity by eliminating the need to shutdown 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; PLC-Controls (for Automatic, Hybrid version)
  • Compartmentalized design, with easy access for filter replacement and serviceability
