Mini Spring Actuators (MSA)

There are a number of lids in any aircraft lavatory. They require a range of characteristics from the motion control components that determine how these lids operate. Some lids need to gently close by themselves to comply with fire protection regulations. For others, the focus is more on convenience. The latter aspect is of particular relevance for business class and first class restrooms that are designed to surround passengers in luxury.

We’ve developed motion control components across this broad range of applications for you that leave nothing to be desired. Choose between ready-to-install hydraulic and electro-mechanical technologies.

Mini Spring Actuators (MSA)

light, yet powerful …

These extremely lightweight hydro-mechanical actuators are real powerhouses. In airplane lavatories, MSAs ensure that the lids of trash containers close smoothly, with a preset delay, protecting passenger fingers and preventing banging noises. The MSA also ensures that lids remain securely shut under all conditions, providing compliance with fire-protection regulations.

Since our Mini Spring Actuators are available in extension or compression versions, you can also use them for many other applications that require smooth lid operation.
