The sensitive one...

Sensitive parts (glass panes, paper) sometimes have to be suctioned with great care. This is a welcome task for the adjustable VDF vacuum ejector. The adjustability optimizes energy, holding power, and air consumption.
Despite the sensitivity the VDF is quite a guzzler. It transports, doses, or suctions even fluids, which makes it ideal for dosing, suctioning, and filling units.
For your special needs (food industry, explosion-risk area, etc.) we can also deliver the VDF is a specific material, such as e.g. stainless steel (AISI 303, 304, 316, 316L), PVC, or Delrin. Delivery times and prices upon request.
Simply order it on trial and adjust it to your parts - you will be surprised!
Matching fittings can be found under Accessories and hoses under Fluid Technology.

Note: For max. performance the connection diameter for the air intake should be the same as flow through øA.
