HW‑304 rotor with a ceramic shaft

This is an original SunSun replacement impeller for the HW-304 filter, intended for aquarists who need to swap a worn or lost rotor without replacing the whole unit. It is supplied with a ceramic shaft, the feature that distinguishes this variant.

Why it matters

• Original manufacturer part: sold under the SunSun brand with the model-specific symbol SUNSUN WIRNIK HW-304, so the fit is matched to the HW-304 rather than a generic rotor.
• Ceramic shaft: the impeller is delivered with a ceramic axle (ośka), which is the material specified for this version.
• Single-item replacement: it is a standalone spare part, so only the rotor needs to be changed when the original one is damaged or missing.
• Easy to identify: the EAN 5903900048675 allows the exact part to be verified before ordering.
