Control versions
With its multi-stage
ejectors, CMS series,
COVAL proposes an
adapted response to all
applications which need
high suction flow; like
emptying of high volume
tanks or handling of
porous objects.
Thanks to their
characteristics, the CMS
multi-stage vacuum
generators are perfectly
appropriate to feed the
vacuum grippers from
distance.
