The PK200 is the big one in the EC-Blue line. It moves up to 1350m3 per hour through a 200mm flange. That clears the air in a room full of lights. The clever part is the draw: EC tech keeps it to 0 to 170 watts, so the meter does not spin the way the airflow might suggest.
Its EBM Papst motor runs quiet and changes pace smoothly, not in jumps. Plug an ECTC-1 into the RJ45 port. Set a floor speed and a top speed. From then on the fan watches the room and sorts itself out. Bracket, cable and a year of warranty come with it. We always run a fan this size onto a 200mm carbon filter so the exhaust is scrubbed before it goes anywhere.
