SAVE VSR 400 — ventilation selection details
Systemair identifies SAVE VSR 400 as a horizontal/ceiling-balanced ventilation unit with rotary heat exchanger and separate supply/extract air paths. Its published user instructions require the correct filter kit for outdoor air quality and describe the rotor assembly, drive cable, sensor cable and cleaning procedure. It belongs to the VSR rotary family, not the counterflow VSC family.
Integration/installation caution: Before specification, confirm handedness, mounting clearance for rotor cleaning, fan operating point at actual duct static pressure, filters, electrical supply and controls. Isolate electrical mains for rotor service; delivered ventilation rates require commissioning.
