50F and 60F are the largest FRP monolithic blades available on the market, with a very wide range of diameters starting from 12ft up to 40ft. Keeping the same shape and characteristics or 50F, the 50L option in extruded Aluminium, allows to face high temperature requirements.
The special blade profiles are designed for super low noise application on Air Fin Coolers, Air Cooled Condenser and Cooling Tower projects, allowing up to 10 dB(A) noise reduction respect to standard products and with the main advantages to maintain, for such a low noise level, high values of efficiency typical of the standard pultruded blades.
