Ospa Monoblock Filter System 1980 Disc Valve

Ospa Monoblock Filter System (approx. 1980) – Disc Valve (reconstructed)

This project represents a faithful reconstruction of the disc valves for an Ospa Monoblock Filter System from the early 1980s. The original parts are generally severely aged, extremely porous, and no longer reliably functional after more than 40 years, and spare parts are no longer available from the factory.

The models provided here were dimensionally precisely reconstructed according to the original valves and are precisely fitting for direct replacement.

Features

• Reconstruction identical to the original geometry
• Precisely fitting for Ospa Monoblock Filter Systems (built approx. 1980)
• Suitable for 3D printing, preferably PLA
• Ideal for repairing historical Ospa filter systems
• Replacement for original parts no longer available

Printing Recommendation

• Material: PLA
• High wall thickness recommended
• 100% Infill or very high infill density
• Clean print without gaps or under-extrusion

Post-Processing / Sealing (strongly recommended)

Since the component is permanently in contact with water and pool chemicals, the printed parts must be additionally treated with a suitable sealant (e.g., Diamant Hydro) to:

• Prevent water absorption
• Increase chemical resistance
• Significantly extend the lifespan

Assembly Note (important)

The brass sleeves of the original parts must be taken over.
These are removed from the old parts and melted into the newly printed valves.
Without this step, proper assembly is not possible.

Note

This is a replacement part for existing systems and is intended for users with technical experience in pool and filter technology.
Use is at your own risk.

Ospa Monoblock Filter System (ca. 1980) – Reconstructed Disc Valve

This project provides an accurate reconstruction of the disc valves (Tellerventile) used in Ospa Monoblock filter systems from the early 1980s.
After more than 40 years of operation, the original parts are typically severely aged, extremely porous, and no longer reliable. Original spare parts are no longer available from the manufacturer.

The models provided here were precisely reverse-engineered from original components and are dimensionally identical, allowing a direct, perfect-fit replacement.

Features

• Faithful reconstruction of the original geometry
• Perfect fit for Ospa Monoblock filter systems (circa 1980)
• Designed for 3D printing, preferably in PLA
• Suitable for restoring legacy Ospa pool filtration systems
• Replacement for obsolete original parts

Printing Recommendations

• Material: PLA
• High wall thickness recommended
• 100% infill or very high infill density
• Clean, gap-free print without under-extrusion

Post-Processing / Sealing (strongly recommended)

As the part is in permanent contact with water and pool chemicals, the printed components must be additionally sealed using a suitable coating (e.g. Diamant Hydro) in order to:

• Prevent water absorption
• Improve chemical resistance
• Significantly extend service life

Assembly Note (important)

The brass sleeves from the original parts must be reused.
They need to be removed from the old valves and thermally inserted into the newly printed parts.
Proper installation is not possible without this step.
