About this product

Please note: this is a non-returnable item (excluding faulty goods)

Fermax 3289 is a filter.

Fermax 3289 filter for power products

Fermax 3289 filter, White

Who this is for

For the installer — this is the filter supplied under Fermax part number 3289. Specify it by that part number.

The entries in the specification table are the ones held against this part number. Anything not listed there is not stated by us, and should be confirmed against the manufacturer's own documentation.

In plain English: this is a filter made by Fermax. The part number 3289 is the manufacturer's own code for this exact version of it.

Similar-looking items in the same family often differ only by a suffix on that code. If you are replacing something, match the code rather than the picture.

Buying this in the UK

We are a UK supplier and this filter is sold and shipped from the UK. Prices are shown in pounds sterling.

This item is non-returnable, excluding faulty goods. That restriction comes from the manufacturer's own terms for this line.

We do not quote a warranty term for this part. Every supplier-stated term we have checked against the manufacturer's own document has turned out to be wrong, so we would rather say nothing than say something we cannot stand behind.

Ask us and we will check it for you. Your statutory rights are unaffected.

Stock on this line moves, and lead times move with it. Ask us for the current position before you commit to a date on site.

Questions we get asked

Is this the exact filter I have been quoted? Check the manufacturer part number 3289 against your quote. That code is the only reliable identity for this item.

Is there a datasheet? Not on this listing. The documents available for it named only the wider family or a different item, and a near-miss document is a wrong document.

Can you check compatibility for us? Ask before you order and we will check it against the manufacturer's own documentation. We do not state compatibility that the record does not carry.

Why does the listing not answer every question? Because the specification held against 3289 answers some questions and not others. We would rather leave a gap visible than fill it with something we cannot show you.

What if I order the wrong version? Tell us the installation you are matching and we will work back to the part number with you. That is a faster conversation than a return.

Do you hold this in stock? Availability on this line changes through the week, so the honest answer is to ask us on the day. We will give you the current position rather than a general one.
