Frequently Asked Questions

Does the Rocker Lafil 400 pump require adding or changing lubricating oil?
The device uses dry-running piston technology without any lubricating oil, so users never need to change or refill oil throughout its operation.

Does the 52 dB noise level affect the workspace?
A noise level of 52 dB is equivalent to a quiet conversation, allowing the pump to operate smoothly and be placed directly on the laboratory bench without causing disturbance.
