Astral (genuine) / Generic option available
📝 Description
The Astral SP78082 is the genuine 135 sq ft replacement cartridge element for the Astral / Hurlcon Viron QL540 cartridge filter, about 680 mm long and 170 mm wide with a 75 mm centre hole. Each QL540 uses four elements, sold individually here, and a lower-cost generic element (HA135Q) is also available.

💡 Before You Buy
-
Order 4 for a full set. The QL540 holds four elements, and each one is sold separately.
-
QL540 or QL420? Both use elements of the same size but different filter area. The QL420 needs the QL420 105 sq ft element.
-
Check your filter model. The model is on the label on the filter tank. See all our filter elements for other sizes.
❓ Common Questions
