A wide range of blades made of high quality engineered plastics, aluminium and electrically conductive plastic (PACAS), guarantee that the safety and longevity requirements for your application can be met.
The hubs are made of Aluminium and a range of special drop-forged aluminium center bosses are available.
|Symbol||Material Description||Temperature Range||Characteristic||Application Suitability|
|PA||Glass fiber reinforced polyamid (nylon, black)||-40°C to 110°C||Heat ageing stabilized||Standard Duty|
|PAG||Glass fiber reinforced polyamid (nylon, beige)||-40°C to 110°C||Heat ageing stabilized||Heavy Duty|
|PACAS||Carbon fiber reinforced polyamid (nylon, grey)||-35°C to 100°C||Electrically conductive, flame-retardant||Duty in explosive environments|
|ALU||Die cast aluminium||-40°C to 150°C||High strength to weight ratio||High temperature|
For corrosive environments, the impellers can be supplied with a protective coating and stainless steel bolts and nuts.
For European compliance with regulations ATEX 100 and VDMA 24169, hubs are available with conductive coatings.
