Fluval 07 Motor Head 207

• Genuine Fluval A20102 – matched to the 207 canister; the 107 head looks similar but is a different rating and will not give you 780 L/h.
• Restores 780 L/h rated output – and the 460 L/h the filter actually circulates once media is loaded.
• Shares its impeller with the 107 – impeller A20109 covers both, so a spare bought for one still fits the other.
• Solves noise the impeller cannot – if a fresh impeller and shaft did not quieten the filter, the wear is inside the head.

• 1 x genuine Fluval motor head for the 207, part A20102, with sealed motor, pump housing, mains lead and plug

Fluval supplies this head bare. A head fitted without an impeller will not pump.

• The magnetic impeller. Order the impeller with ceramic shaft and rubber bushings (A20109), or move the old one across if it is clean and unchipped.
• The impeller cover. See the impeller cover (A20133).
• The motor head gasket. Reusable if still soft, but a head swap is the moment to renew it – see the motor head gasket (A20038).
• The canister, baskets and media. This is the top section only; the canister case for the 207 is separate.

The motor head maintenance kit for the 207 (A20095) covers the wear items in one go.

It fits the Fluval 207 and nothing else. Owners often assume the 107 head will do, because the two canisters share a footprint and an impeller – but the motors are rated differently and are not interchangeable. It does not fit the 107, 307 or 407, nor the 206, 205 or earlier, nor any FX-series filter. Fluval lists no supersession for A20102.

The four 07 heads are not interchangeable – each is matched to its own canister and motor rating. The model code is printed on the compliance label under the canister.

Fluval publishes three figures for the 207, describing three different situations. Only the middle one resembles a real installation.

Fluval publishes no intermediate points, so no curve is reproduced here rather than an interpolated one being invented. Expect flow to fall steadily as lift, hose length and elbow count increase. Note also that Fluval measures output at 120 V / 60 Hz; Australian units run at 240 V / 50 Hz, where the published draw is 10 W.

Suitable for a 207 with a seized or burnt-out motor, a scored rotor chamber, a cracked volute, or water weeping from the motor body itself. Also where a grinding noise persists after a new impeller and shaft have been fitted.

Not suitable for low flow caused by clogged media, a blocked intake strainer or a partly closed AquaStop valve – check those three first, in that order.

Supplied for 240 V / 50 Hz with an Australian plug. Unplug at the wall before removing the head, and never power it up with the canister open or dry – the bushings are water-lubricated and a dry start does measurable damage.

The mains lead is moulded into the sealed motor and cannot be replaced separately, so a damaged cord makes the head scrap rather than a repair. Run the filter on an RCD-protected circuit and form a drip loop in the lead. To make the head last, wipe the rotor chamber at every service – grit and calcium there is what scores the chamber and eventually kills the motor – and lubricate the gasket with silicone lubricant, never petroleum jelly.

• 07 output nozzle – for a return jet that has gone brittle or discoloured
• Media basket cover – worth checking while the head is off, since a cracked one lets water bypass the media
• Motor head for the 107 – if the compliance label says you have the other model

Supplied as a genuine Fluval service part. Fluval does not publish a separate warranty term for individual replacement parts; the published warranty attaches to the complete filter. Your rights under the Australian Consumer Law apply in full and nothing stated here limits them. Ships as a standard parcel anywhere in Australia, with no dangerous goods restrictions.

Does the Fluval A20102 motor head include the impeller?

No. The A20102 head is supplied without the magnetic impeller and without the impeller cover. Order impeller A20109, which fits both the 107 and the 207.

My Fluval 207 is noisy even after a new impeller. What now?

That points at the head. When a fresh impeller and ceramic shaft do not quieten the filter, the wear is in the rotor chamber inside the motor head, which cannot be resurfaced and is replaced as a complete assembly.

What flow should I actually expect from a 207?

Fluval rates the 207 at 780 L/h as bare pump output and 460 L/h as filter circulation with media loaded. The 460 L/h figure is the one to size a tank against.

Can I fit a Fluval 207 motor head myself?

Yes. It lifts off after releasing the two canister clips and needs no tools. Unplug the filter at the wall first and have a towel ready, because the head holds water when it comes off.
