Think big! Be smart! Ospa vacuum filter

Made in Germany

Clean and economical, Ospa vacuum filter for permanent efficiency

Best filtration – fewer chemicals

The fundamental concept of the swimming pool filter from Ospa: filter out the maximum possible contaminants through optimal filtration. The better a filter removes organic contaminants, the less chemical water disinfection is required. Then the water can be gently disinfected.

Hydroanthrasite S in the 0.6–1.6 mm particle size group and filter quartz sand in the 0.4–0.8 mm particle size group as well as supporting layers with varying grain size are used as filter layers in Ospa vacuum filters. Properties similar to those of activated carbon are achieved by the specialized Ospa hydroanthrasite S. As a result, Ospa vacuum filters are able to reduce combined chlorine and other organic chlorine compounds, such as THM and AOX.

Convenient and secure

The vacuum filter technology from Ospa is significantly more energy efficient than other solutions, due to its BlueControl® filter control, which is unique on the market. It also provides for maximum convenience. Thanks to the latest control technology, the vacuum filter systems from Ospa operate fully automatically.


Maximum energy efficiency

Resource-conservative energy efficiency works best when all components are ideally coordinated with each other: Ospa provides you with sophisticated system technology for this and the know-how of more than 65 years of research and development. All components of Ospa swimming pool technology are designed for energy-saving operation. In addition to the filter, that also includes the FC-controlled untreated water and filter pumps. With Ospa, a separate backwash pump can be completely eliminated thanks to the innovative BlueControl®.

Filtration process

Backwashing process

How do Ospa vacuum filter systems work?

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

The filter vessels are produced in a rectangular design from polypropylene: closed on top, with removable cover, connection for safety overflow to the water reservoir, electronic level monitoring, viewing windows for visual inspection of filter operation and layer separation during filter backwashing, lateral manhole and access opening under the nozzle bottom. Untreated water inlet and sludge water discharge device for DIN-compliant, unpressurized filtration and backwashing operation of the filter system, for uniform vessel flow and uniform distribution of contaminants over the entire filter surface without removal of filter material, at backwashing speeds according to DIN 19643 of 50–55 m/hr. The Ospa multi-layer suction filters have a nozzle bottom with supporting and filter layers arranged on top.

In accordance with DIN 19643, the filtering layers consist of 400 mm quartz sand, in the 0.4–0.8 mm particle size group, and 400 mm hydroanthrasite S, in the 0.6–1.6 mm particle size group, with properties similar to those of activated carbon. As a result, they are able to reduce combined chlorine and other organic chlorine compounds which are adsorbable on activated carbon, such as THM and AOX. Electronically controlled pneumatic flaps for fully automatic filter backwashing and channel discharge of first filtrate. Closes automatically in case of power outage or compressed air failure.
