AstralPool - Filter Manifold Arm 3/4" 225 mm (Pack of 4) - SP-04-0028

AstralPool – filter manifold arm 3/4″ 225 mm (pack of 4)

This is a genuine AstralPool replacement manifold arm (also known as a lateral collector arm) with a 3/4″ threaded connection and a 225 mm length, supplied as a pack of four units. These slotted arms mount onto the central manifold hub inside AstralPool sand filters, distributing and collecting water evenly across the filter bed during both filtration and backwash cycles.

Cum funcționează

During normal filtration, the manifold arms recover clean, filtered water from the base of the sand bed and return it to the pool. During backwash, pressurised water is forced back through the arms, lifting and agitating the filter media so that trapped debris can be flushed out and expelled to waste. Correct arm length and thread size are critical for balanced flow across the entire filter bed.

Compatibilitate

These 225 mm, 3/4″ manifold arms are designed for use with AstralPool sand filters that specify this arm length and thread size — including models in the Millennium and related filter families that use a standard manifold hub configuration. Always verify the required arm length and thread specification against your filter’s parts diagram before ordering, as AstralPool filters use several different arm lengths.

De ce autenticitatea contează

Genuine AstralPool parts are manufactured to exact dimensional tolerances, ensuring a secure 3/4″ threaded fit, consistent slot geometry for even flow distribution, and full chemical resistance to pool water and backwash pressures. Off-brand arms can create uneven filtration, bypass sand, or fail prematurely under backwash pressure.
