Sand or flint are the most used materials in domestic swimming pools. The sand retains the dirt of the water when it passes through the pores that form in it due to its irregular shape. As an inconvenience, the sand needs maintenance because if channels are formed in it, the water passes directly back to the pool without being filtered. Another of the drawbacks is the ability of the sand to retain bacteria and microorganisms, which can cause them to proliferate inside the filter.

It is a granular anthracite, for use in the filtration of suspended solids. The particle size directly affects the filtration efficiency. A large particle size allows a longer filtration time between contralavados, although it requires a higher bed height. A small particle size allows for a low bed height, but causes a greater pressure drop.

The vitreous filter medium is environmentally friendly, it is made of recycled glass. It is more efficient because it saves on washes and water, as well as energy costs and chemical treatments.

Zeolites are a porous material of natural origin, exceeds the filtration quality of classical substrates such as flint sand and is comparable to that of diatoms, with a tighter price and a much longer duration.

The OC-1 solution is a combination of OC-1 media and filters that offer excellent results in the filtration of a pool or spa. It can be used in both residential and public swimming pools. Save time by reducing the frequency of cleaning. Save energy using a smaller pump or reducing its speed. Save water by reducing water consumption by washing your filter against the current. Enjoy excellent quality water in your pool or spa.


Winding filters made of polyester reinforced with fiberglass, totally anti-corrosive, presenting a high mechanical, chemical and thermal resistance.

Sight Glass
Ref – S

The sight glass is an optional component of the filter that is used to observe the inside of the filter, the level of the filter medium and its expansion during washing. By default it is manufactured in PMMA. If the inside of the filter is coated with vinyl ester, it is made of tempered borosilicate glass. It is placed centered with the maximum level of the filter bed and to the left of the connections.

Lateral manhole
Ref – L1 / L2 / L4 / L5 / L6

Lateral manhole. By default, it is placed to the right of the connections. Manufactured in GRP with nuts and bolts in AISI 316 stainless steel and EPDM gasket. It can be placed in different positions according to customer requirements.

Top Manhole
Ref – T5 / T6

Top manhole Ø400 (16”) for access and loading of the media filter. It is placed as a standard part and it is centered on the filter. Ask the possibility of placing off-center if desired according to models.
