Ospa vacuum filters

Ospa vacuum filters for lasting efficiency

Superior filtration – less chemistry

The core principle of Ospa’s pool filters is to remove as many impurities as possible through optimal filtration. The better a filter removes organic impurities, the less chemical water disinfection is required, enabling gentle water treatment.

Ospa vacuum filters use filtration layers consisting of hydroantracite S with a grain size of 0.6 – 1.6 mm, filter quartz sand with a grain size of 0.4 – 0.8 mm, and supporting layers with varying grain sizes. The specialised Ospa hydroantracite S exhibits properties similar to activated carbon. This allows Ospa vacuum filters to reduce combined chlorine and other organic chlorine compounds, such as THM and AOX.

Convenient and safe

Ospa’s vacuum filter technology, powered by its unique BlueControl^® filtration system, is significantly more energy-efficient than other solutions on the market. Additionally, it offers maximum convenience. Thanks to state-of-the-art control technology, Ospa vacuum filter systems operate fully automatically.

Perfectly coordinated system technology for maximum hygiene How do Ospa vacuum filter systems work?

The fully automatic Ospa multi-layer vacuum filters use the suction filtration process.

The filter tanks are made of rectangular polypropylene: closed at the top, with a removable lid, a connection for a safety overflow into the water water balance tank, electronic level monitoring, sight glasses for visual inspection of filter operation and layer separation during filter backwashing, a side manhole, and a maintenance opening below the nozzle plate. Raw water inflow and sludge water outflow systems ensure DIN-compliant, pressure-free filtration and backwashing operations. These systems provide uniform tank flow and consistent removal of debris across the entire filter surface without discharging filter material, even at DIN 19643 backwash speeds of 50 to 55 m/h.

The Ospa multi-layer suction filters feature a nozzle plate topped with supporting and filtering layers.

The filtering layers comply with DIN 19643 and consist of 400 mm of quartz sand (grain size 0.4 – 0.8 mm) and 400 mm of hydroantracite S (grain size 0.6 – 1.6 mm), with properties similar to activated carbon. This enables them to reduce combined chlorine and other organic chlorine compounds, such as THM and AOX, that can be adsorbed by activated carbon.

Electronically controlled pneumatic valves enable fully automatic filter backwashing and channel discharge of the first filtrate. In the event of power or compressed air failure, the valves close automatically.
