The PLURAFIT PF 300-150 Calm allows removal of the bottom bowl and therefore can be cleaned in installed condition. DN150 pipes can be directly fitted to the spigot end of the inlet calmer.
With course of time, fine particles settle at the base of the tank and form a sediment layer. In order to avoid swirling of the sediment layer by inflowing rain water, the water must be steadily supplied to the tank. The inlet calmer leads the rainwater to the tank in the direction of flow created at the base of the tank - the sediment layer is not disturbed. Pumps and other parts of the system are subject to less wear and therefore have higher durability.
