Seramodule air 275 R plus + 550 R plus

The sera air pump I bought a couple of years ago, has been brilliant, until about a week ago, when it started making an awful rattling noise. So found this replacement part to fit, as you can see in the photo , the old one had split! The new one is working like a dream, nice and quiet, and pumping air full blastHappy customer happy fish.Very easy to fit, thumbs up from me. Not expensive either. Brilliant.

only after purchasing the replacement membranes and installing as recommended in the diagrams as illustrated in the front of the instruction booklet some 7 months previous and has now failed again I found out after closely reading the booklet that the membranes must be replaced every 6 to 12 months at a cost of approximately half the price of a new pump none of this information is displayed on the sales or technical information at point of purchase if I had known this I would have not purchased the pump

good replacement for a faulty one, works well

Non conoscevo l'esistenza del ricambio e stavo per buttare tutta la pompa areatore, poi per scrupolo ho fatto una ricerca e ho trovato proprio quel che mi serviva. Ordinato e in tempi rapidissimi ho ricevuto per pochi euro il ricambio perfettamente compatibile con il precedente. Messo in funzione va che è una meraviglia. Sono soddisfatto del ricambio e del servizio spedizioni.

Eigentlich sind die Module für das Preis-/Leistungsverhältnis im Vergleich zum Neukauf erheblich zu teuer...wenn man bedenkt, dass ggf. jährlicher Austausch erforderlich werden kann.
