Astral - Main Drain with Anti-vortx Lid - Suitable for Concrete Spas

Manufactured in white ABS, the drain has UV protection and is used to take in water from the deepest part of the pool for 100% recirculation. It is also used to drain the pool. The latest models include a grille that complies with current regulations, in which the distance between the holes is less than 8 mm to prevent entrapment of bathers' fingers. Likewise, the "antivortex" models use lateral suction to prevent whirlpool.

The flat-grille drain, is the most appropriate model for shallow pools

New range of Main drains according the normatives EN-13451-1 and EN-13451-3, available for public and private pools, supplied with flat grilles or antivortex grille.

Top Tips:

  • As a safety measure, two drains should be installed in each pool at a minimum distance of 2m
