Make Sure You Are Ordering the EC Bag

Astralpool uses separate component bags for the EC, ECA and CA filter families, and they are not interchangeable. Confirm which filter you have before ordering:

• EC series, 40mm - this bag, part 78336.
• ECA series, 40mm multiport - Component Bag 40mm ECA Multiport 78355.
• CA series, 40mm filter - Component Bag 40mm CA Filter 78334.
• CA series, 40mm multiport - Component Bag 40mm CA Multiport 78356.
• CA series, 50mm filter - Component Bag 50mm CA Filter 78335.

Telling an EC Filter From an ECA Filter

EC and ECA filters look very similar. The reliable way to tell them apart is the outside diameter of the centre pipe (the standpipe inside the tank that the multiport valve seats over):

• 50mm O/D centre pipe = EC series. This bag, part 78336.
• 48.1mm O/D centre pipe = ECA series. Use the ECA parts instead.

Check the filter's model label as well before ordering. If you are unsure, send us a photo and we will confirm.

Frequently Asked Questions

Will the 78336 bag fit my ECA550 or ECA650 filter?
No. 78336 is the EC series bag. ECA filters use their own component bag, part 78355. The centre pipe measurement tells you which family you have: 50mm outside diameter is EC, 48.1mm is ECA.

What is the difference between a filter component bag and a multiport component bag?
Fluidra lists them as separate parts at different prices, so they are not the same bag. Tell us which fitting you are replacing and we will point you to the correct one.

I only need one fitting out of the bag. Can I buy it separately?
Often yes. Many EC and ECA filter fittings are stocked individually. Contact us with a photo of the part and we will check whether it can be supplied on its own.

How do I confirm which filter model I have?
Check the model label on the filter tank, and if that is missing or unreadable, measure the centre pipe outside diameter and send us a photo of the filter and valve.
