AstralPool - Filter Base Ø 750 mm for Berlin Filter 4 Bar - 4404010407

AstralPool – Filter Base Ø 750 mm for Berlin Filter 4 Bar

This is the genuine AstralPool replacement filter base designed specifically for the Berlin Filter 4 Bar (Ø 750 mm, SKU 21729). It forms the structural foundation of the filter tank, supporting the vessel and providing a stable, level footing during operation. As Position 9 in the official Fluidra exploded-view diagram, it is a precise OEM part engineered to exacting factory tolerances.

Compatibilité

This filter base fits the AstralPool Berlin Filter 4 Bar Ø 750 mm (parent SKU 21729). The Berlin 4 Bar range is a specialist bobbin-wound sand filter rated for an elevated operating pressure of 4 kg/cm², available by special order from AstralPool. It is not interchangeable with the standard 2.5 bar Berlin series bases or bases for other diameters. Always cross-reference the exploded-view position (Position 9) and your filter’s model number before ordering.

Pourquoi l'authenticité est importante

The Berlin Filter 4 Bar operates at higher-than-standard pressure, making a correctly rated, OEM-certified base essential for safe, leak-free performance. Genuine AstralPool parts are manufactured to the same specifications as the original component, ensuring a perfect fit and maintaining the filter’s pressure rating and warranty compliance. Third-party alternatives may not meet the 4 bar pressure requirement or match the exact mounting geometry of the Ø 750 mm vessel.

Installation

The filter base is a structural component typically replaced during a full filter overhaul or when the existing base shows cracking, warping, or instability. Installation should be carried out by a qualified pool technician. Ensure the filter vessel is fully depressurised and drained before disassembly. Refer to the official AstralPool Berlin Filter installation and maintenance manual for torque specifications and reassembly guidance.
