For optimum protection of geared motors against ambient
conditions, the surface and corrosion protection system
(OKS) offers tailor-made solutions.
Various surface coatings combined with other protective
measures ensure that the geared motors operate reliably
even at high air humidity, in outdoor installation or in the
presence of atmospheric impurities. Any colour from the
RAL Classic collection can be chosen for the top coat. The
geared motors are also available unpainted (no surface and
corrosion protection).
