Laskin nozzle aerosol generator with pressure gauge and controls

Product Overview

The HM-QRF from HM Instruments uses Laskin nozzles to generate challenge aerosols for cleanroom and filter leak-testing work. An internal compressor supplies the air, while the nozzle selection and pressure setting control aerosol production.

Key Features

  • Selectable 4-nozzle or 10-nozzle operation supports different air-volume requirements.
  • The internal compressor provides the compressed-air supply.
  • Compatible aerosol media include DOP, DOS and PAO as specified for the test.
  • Pressure control and adjustable aerosol output support challenge-aerosol setup.

Applications

Use in cleanroom and filter leak-testing workflows at medical-device testing facilities, disease-control laboratories, hospitals, pharmaceutical facilities and filter manufacturers. Pair the generator with a suitable aerosol photometer and select the challenge concentration for the system being tested.

Operation and Support

Keep continuous aerosol generation to no more than one hour, then stop spraying and cool for 15 minutes before resuming. After use, allow 20 minutes of cooling before disconnecting power. When using an 8 mm quick connector, keep the connected narrow-bore tubing within 10 cm to avoid excessive pressure. Fill and drain the aerosol liquid according to the operating procedure.
