Waterco 200370 Multicyclone 50 Pre-Filter 2 in - 50Mm

Cleaner Water, Longer Filter Life with Inline Multicyclone Pre-Filter

The Waterco 200370 Multicyclone 50 Pre-Filter is an inline cyclone pre-filter designed for 2-inch (50 mm) pool and spa circulation lines. It traps larger debris before it reaches the main filtration system, helping extend cartridge life and maintain consistent flow. This compact unit fits standard 2" plumbing and is ideal for both new installations and retrofits in pool and spa equipment layouts.

Construction, Compatibility and Integration

Built with a durable polymer body and sealed connections, the Multicyclone 50 is designed for outdoor pool or spa environments. It accepts 2" (50 mm) piping and standard unions used in most circulation systems, allowing straightforward installation before the primary filter or downstream equipment. The cyclone mechanism separates heavier solids via centrifugal action, reducing load on the main filter and helping sustain steady flow across the system.
