Silent operation and efficient ventilation of the whole dwelling
The V4A²’s EC-Motor (Electronic Commutation Motor) adjusts its speed/torque using an electronic card. This feature helps maintain the required pressure, ensuring that airflow matches the requirements of the connected demand-controlled exhaust units. This keeps power consumption and noise emissions to a minimum.
New and improved SFPs as low as 0.16W/l/s for both rigid and semi-rigid duct resulting in better DEAP and SAP results. Listed on the PCDB Appendix Q.
