Description:

NVT centrifugal fans are low-pressure used for ventilation in places were required pressure does not exceed 1500 Pa and air flow requirements are in between 0.1 and 20 m3/s. In case of direct drive air temperature should not exceed 60°C or 100°C in case of belt drive.

Because of NVT fans cover wide area of air flow they are used in wide area of applicaton such as: ventilation and air conditioning systems of public and industrial buildings, in agriculture machinery, ships and shipyards.

NVT centrifugal fans have specially designed impellers that enable NVT fans to have relatively high air flow with low to medium pressure rise.

Design

NVT fans up to size NVT-280 are manufactured only as a single intake fans in direct drive (labeled as NVTe). Sizes from NVT-560 up to  NVT-900 are manufactured only in belt drive version (labeled as NVTr).

NVT-315 up to NVT-900 can have multiple different positions of outlet flange according to sketches in below.
