Surface and corrosion protecon (called OKS)
Depending on the ambient condions, the surface and corrosion protecon system (called
OKS) oers tailor-made soluons for opmum protecon.
Various surface coangs ensure that the motors operate reliably even at high air humidity, in
outdoor installaon or in the presence of atmospheric impuries. Any colour from the "RAL
Classic" collecon can be chosen for the top coat.
For the indoor installaon and if no special corrosion protecon is required, the products are
also available unpainted (without OKS).
Without OKS (unpainted):
The aluminium parts ar
e not coated and grey cast iron parts are primed with
grey paint. Slight colour dierences of the components are possible.
