The  slim design of the SI-20 allows it to easily fit inside a mini-split air conditioner, but also alongside the unit (in lineset cover).

The Sauermann piston technology inside the Si-20 is specifically constructed for removing condensates from air conditioning systems. This technology makes the Si-20 fully reliable in any kind of environment.

The operating sound level of the Si-20 will remain low (22 dBA) whatever the amount of condensate. The Si-20 pump is fitted with unique rubber dampers designed to reduce noise caused by vibration.

The Si-20 is also fitted with a pre-installed Drain Safe Device, for a unique reliability in any kind of installation.
