Description

The Hayward Pro Series Sand Filters are the very latest in pool filter technology to produce sparkling clear water with minimum effort. The weather proof tank is molded of durable, corrosion-proof, color-fast polymeric material and utilizes full size internal piping for a free-flowing performance.

The filter is topped with the versatile 7-position Hayward Vari-Flo control valve, with the easy-to-use lever-action handle lets you dial any of the 7-valve/filter functions for easy operation. The integral top diffuser, self-cleaning under drain and 360-degree slotted laterals ensure even water distribution over every square inch of sand with thorough backwashing and a totally balanced flow. The Pro Series Sand Filters offer the ideal combination of energy efficiency and durability. Back to Top

More Info

Sand is the oldest and most popular method of filtration. Sand filters share two things in common:
1. When in the filtration mode, water always flows from top to bottom

2. They all have some sort of lateral or under drain with slots to hold back sand while allowing clean filtered water to pass through.

High-rate sand filters use a special filter sand, normally .45 to .55 mm (also known as pool grade #20 silica sand), because it has sharp edges that separate particles, allowing filtration to take place. They operate on the basis of "depth" filtration where dirt is driven through the sand bed and trapped in the spaces between the sand particles. A clean sand bed removes larger particles, and as the bed starts to load up with debris, the filter removes the finer particles. The sand can be cleaned by backwashing, which involves reversing water flow through the filter to the "waste" line. Sand filters trap debris as small as 20 to 40 microns.

A little-known fact is that a sand filter operates most efficiently during mid-cycle. Debris trapped in the sand bed actually help the filter work better so frequent backwashing reduces efficiency. Sand filters should only be backwashed when the filter has collected so much debris that it begins to restrict water flow and increase water pressure.
