The skimmer flap in anthracite colour is an original replacement part for Astral skimmers of models 11309, 11310, 11311, 11313 and 17109. The flap is made of durable ABS plastic, which resists UV radiation and pool chemistry without loss of colour or shape stability.
The function of the flap lies in controlling the flow of water entering the skimmer – it prevents the backflow of dirt into the pool when the pump fails and regulates the suction intensity. The smooth, non-slip surface prevents the deposition of algae and limescale.
Replacement of the flap is quick and requires no tools – the new part simply slides into the groove of the existing skimmer body. The anthracite colour goes perfectly with modern pools featuring dark wall finishes or grey tiling.
