Hayward filter PRO HL BTL

Hayward filter for private swimming pools

A few years ago, Hayward took over the Kripsol company – this was for the filters, among other things! The new Hayward filter has many qualities.

• Laminated polyester filter reinforced with glass fibres
• Twist-Lock system for easy opening and quick tool-free access
• Variflo™* 6-way valve, robust and reliable
• Optimal distribution of water on the filter media, thanks to the Dual-Side diffuser
• Simplified maintenance thanks to the drain and quick couplings
• All models have a pressure gauge
• Transparent lid

Sand filter quality

Hayward comes with these new laminated polyester filters of the best quality with an innovative design. The filter is without a plastic "foot" but is made with an integrated bottom for extra strength and a better structure from 1 piece.

The Twist Lock lid makes opening the sand filter very easy and maintenance-friendly. It is a practically designed swimming pool filter with a long service life in mind.

Filling of the filter

The filter can be filled with filter sand or with filter glass. For filter glass beads, we recommend taking 80% of the sand weight to determine the correct amount of filter material.

How do you determine which sand filter to choose

To obtain clear swimming pool water, it is important that the Hayward filter is properly dimensioned.
