The construction of the Flamcovent has been changed in such a way that in the enlarged bottom bowl a non-turbulent area is created. This allows relatively heavy particles to sink to the bottom of the Flamcovent Clean where there are no vortices to force the particles back into the system again. The collected particles can be drained from the system through the ball valve at the base of the unit. There are no PALL rings or obstacles in the bottom bowl to prevent the collected particles from being drained away.

Lightweight solid particles that float in the water within the Flamcovent Clean can be drained out through the drain valve on the side of the body.

The capacity of the Flamcovent Clean to separate solid particles from the system has been tested and reported on by the Dutch TNO Institute of Environmental and Energy Technology (Report number R95-064). The summary of the results and the conclusions of this report are available if requested.

The operating principle for air separation of the Flamcovent Clean is equal to the standard Flamcovent. For operating principle, selection criteria and technical data please refer to the Flamcovent air separator.
