1.5kW Dayliff DX900 Pool Pump Filter – Industrial-Grade Filtration for Very Large & Public Pools

The 1.5kW Dayliff DX900 Pool Pump Filter is the largest and most powerful system in the Dayliff DX filtration range, engineered for very large domestic pools, commercial facilities, and public swimming pools where maximum flow capacity, durability, and uncompromising water quality are required.

Built on over twenty years of proven filtration engineering, the DX900 features an extra-large moulded GRP (glass-reinforced plastic) filter body, delivering exceptional structural strength, corrosion resistance, and long service life in heavily chlorinated and high-use environments.

A flange-connected six-position multiport valve with union connections provides precise control over filtration, backwashing, rinsing, waste discharge, and recirculation while maintaining a secure, leak-free seal. Internally designed high-efficiency collector laterals ensure excellent filtration and backwashing performance with minimal media loss, even at very high flow rates.

Designed for continuous operation under heavy bather loads, the DX900 delivers crystal-clear water reliability for demanding pool installations where performance and uptime are critical.
