620mm diameter vortex that stands 720mm high.
These vortex units have traditionally been used to aid pond filtration. Made from high quality GRP fibregalss. They are installed before your multi bay filter system and generally work best if they are gravity fed. The priciple on which they work is, the flow of water from the pond is slowly spun to create a vortex, before the pond water is passed on to the other filter bays. Any solid organic waste will be caught in this vortex where it can easily be purged down to waste(drains, sumps, etc). A correctly installed vortex will remove the majority of solid waste from your pond water before it travels into your pond filter. This has the effect of greatly reducing the ammount of cleaning required in your multi bay filter. Also keeping the filter relatively free from dirt will better maintain the filters efficiencey. This vortex is supplied with, but not fitted with, a 1 1/2" discharge valve for purging, and a 4" radial connector for joining pipework into the vortex. Larger valve sizes can be supplied at an additional cost if required. Holes for the radial connector and the discharge valve need to be drilled. This makes the unit very versatile and suitable for most installations.
