Helios Ventilatoren FSK 50/30 (VE2) Duct spigot

For cost-effective integration of rectangular duct fans into round pipe systems. The fittings made of galvanized sheet steel are perfectly fitting to the flange dimensions of the duct fans, therefore easy to fit and screw to the flange points. The use of the fittings affects the flow and reduces the fan output slightly.
