The Trufoil is a versatile and cost-effective alternative to traditional aluminium hub designs for a wide range of industrial cooling applications.

The Trufoil is a versatile and cost-effective alternative to traditional aluminium hub designs for a wide range of industrial cooling applications.

The design features a sheet metal hub to which polymeric blades are mounted via bolted metal cups.

The simplicity of this arrangement has numerous advantages: in particular, it can be tailor-made to provide the most efficient and economical cooling for any application.

By contrast, aluminium hub designs are expensive and limited to a range of standard sizes and blade configurations, which means that they can rarely deliver the optimum solution in terms of output, power usage and price.

The key component of the Trufoil fan is the laser-cut steel hub, which is significantly lighter than aluminium and can be drilled for any number of blades.

The blades are of polypropylene or glass-filled nylon, with an aerofoil profile and a choice of three standard widths.

They can be hub or flange mounted and the design of the steel mounting cups permits infinite pitch adjustment.

Trufoil offers a combination of high performance, low noise, strength, durability and cost-effectiveness in cooling modules, cooling units axial fans and air compressors.

The standard range covers all sizes from 300 to 1200mm, although larger units can be quoted on request.
