Automatic Air Vent

The SpiroTop is a fully automatic air vent, as installation fluid functions best when it contains as little air as possible. In an installation, air gathers at the highest points, which can disrupt the flow or even stop it completely. The SpiroTop removes this air in a fast and effective manner, without the need for maintenance.

Spirotop is the reliable and worry-free solution ideal for:

  •  filling and draining systems
  •  making and keeping the highest points in systems air-free
