Coval - Heavy-duty in-Line Ejectors, VR series

Heavy-duty in-Line Ejectors, VR series

Presentation: . 2 models
. Ø Nozzle : 0.5 ; 0.7 ; 0.9 ; 1 ; 1.2 ; 1.4 mm
. Maximum vacuum : 85%
. Air drawn in 64 Nl/min
. Weight between 20 and 45 g

The main advantage of the VR series in-line ejectors is that they can be mounted directly on the suction cup, which simplifies wiring.
By integrating the ejector into the suction cup we obtain a localized vacuum and, therefore, the possibility of obtaining multiple independent grips, even in the absence of objects.
It is also possible to supply vacuum to two or more suction cups using a 1/8 Gas or 1/4 Gas T-shaped fitting.

Advantages: .Wide range
.Adaptable to all industries
.Lightweight and compact
.Reduced gripping time
.Direct installation on suction cups
.Excellent mechanical resistance
.Blow-off option
.Extended range of suction flow rates
.No clogging
.Silent operation

Further informations: Customized on request
.Alternate material option: stainless steel or plastic, based on specifications.
.Special characteristics such as suction flow rate or vacuum level.
.On request for the F18 model, M5 ancillary vacuum fitting for connection of a vacuum switch.
