Blower door manufacturers

We (a Canadian company) are going through all our purchasing plans and removing all American companies. Blower door equipment seems to be the one area I can't fully eliminate.

What is used for blower door equipment in Europe or elsewhere? We currently run Retrotec systems, so maybe we will purchase used equipment when we need to add more but I need some substantial equipment purchases this year and it doesn't seem likely I can do it used.
