The NovAx ACN are unidirectional axial flow fans for conventional and industrial use.

Optionally the NovAx ACN fans are available as smoke fans. The NovAx ACN smoke exhaust fans are for conventional operation and operation during fires in carparks, commercial and industrial buildings, tunnels and more. The design is tested and approved to meet requirements for smoke exhaust.

The NovAx ACW are extra durable unidirectional axial flow fans for marine use. The main characteristic is the very strong fan casing, which is an expressed requirement from the marine industry and which makes the ACW suited for rough conditions.
