The Primary Vortex:


The Smallest Size for a vortex to be reasonably efficient is the 24inch diameter .. below this diameter the efficiency level declines dramatically.... although we have to say that even a smaller one that sometimes comes as an integral part of a filtration system, is far better than no vortex at all....

We have several models and sizes of the Primary Vortex

Starting with our 24inchdiameter x 36inch tall - like all our Vortex Units, they are all fitted with a waste outlet which is situated in the very bottom of the vortex cone (and not as a side exit - as some manufacturers continue to produce that do not work as efficiently). The largest size we handle is our own 48inchdiameter x 61inch tall models.

All manufactured in GRP (Fibre Glass) and are exceptionally strong and finished in Green ...

Please bear in mind that the cost of shipping on these vortex units and other filtration systems, because of their sheer size and the fact that the carriers today use a volumetric weight and not the actual weight - which means that shipping charges can add quite a lot to the total cost .. these will be shown on the Shopping Cart Checkout forms.

Please note that for 'Gravity Fed' systems the water level in the pond should be no more than 1/2inch from the Top edge of the Vortex Unit with the pump switched off. So if preparing a solid or concrete base for your Vortex units to stand on the base should be laid at the height of the vortex plus 1/2inch.
