Helios RR250C Centrifugal inline fan 250mm diameter
The RR range of in-line centrifugal fans offer a very cost effective way to ventilate using ducting up to 315mm.
These centrifugal fans combine the benefits high-pressure development with easy installation.
Because they are a powerful fan they ensure that the system will move air even when the system resistance is much higher than expected.
Thus the RR range is able to cope with moderate runs of flexible duct as spiral ducting.
Installation is easy with a simple mounting arrangement (accessory MK4 foot) and easy to use connection to ducting using pipe clamps.
