Materials

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.
