Lab-vent Controls A/S - Service

To ensure the fume cupboards always works and have the greatest possible safety for users, the fume cupboards are serviced once a year. Our service engineers are available for this task.
To ensure unintended stops and dangerous conditions for the users, we can offer an annual service inspection of the fume cupboards incl. dampers or fans. We offer a service contract where we, after the conclusion of the contract, automatically contact you, once a year, to arrange a time for the service.

The service includes:

  • The measurement of air velocity in the door opening at the minimum and maximum positions
  • The airflow and the maximum panel height adjusted as needed, so the settings comply with the requirements
  • Hatch-sensor LVL 901 will be inspected for mechanical defects
