Aeromatic which is an iso 9001 certified company by lrqa manufactures variable inlet vane damper having salient features such as energy savings with fans utilizing variable intel vanes; viv dampers often used for capacity modulation. These variable inlet vane damper give accurate modulation and power saving over other conventional dampers at reduced air flow; when an intel vane is particularly closed, each blade directs the air into the wheel in the direction of rotation and so the air is press run. This advanced technology brings about a reduction in capacity determined by the type of system and type of fan vane combination; for every intel vane position there is different capacity v/s static pressure curve and capacity v/s brake horsepower curve generated by fan. The viv dampers come with mechanical principle of adjustment; inlet guide vanes are synchronously adjusted in the same angular positing by connecting element; adjustment can be made either automatically via an adjusting element from pulse generator or by hand.
