Single or twin, the Helios SquareLine in-line centrifugal fan has been designed for installation in circular ducting where there is minimum height or tight spaces like ceiling voids in both commercial and industrial applications.
With six models from 100mm to 315mm nominal diameter, the compact design enables the installer to quickly position with a choice of either top or bottom quick fixing plate supplied as standard. The twin fan combination is achieved with two fans of the same connected with Helios pipe clamps guaranteeing 100 percent standby.
All models are fully speed controllable. The SquareLine is also fitted with a backward curved centrifugal impeller powered by a direct driven motor which is maintenance free and comes complete with sealed for life ball bearings.
The range has protection to IP44, built in thermal protection and can be installed at any angle with simple knock out points in the casing for electrical connection. There is also a full range of accessories including matching silencers and heaters.
