Hybrid

hybrid timer controlled drain

This drain has a fixed interval, but the built-in condensate sensor automatically adjusts the ‘open’ time according to the amount of moisture that’s accumulated.
This minimises the volume of air that’s lost during operation, but simplifies the installation because the drain can never get air-locked. For convenience, it can also be installed in various orientations.
Suitable for up to 2000cfm (60m3/min)
