The article was ordered for a VP MD22. When installing in Greece for winter storage, I noticed on October 30th, 2017 that the thread diameter is too large, so the filter cannot be used. I have an MD22 L. This was particularly annoying as there was no replacement around. So I had to throw out the old filter and use it again. The exact delimitation of the motor types should be improved, as there are several MD22s. I was very annoyed because otherwise I am very satisfied with SVB's offer, service and prices. The ordered impeller, on the other hand, fits perfectly. This as information for all customers.
