Details:

The Fairchild Model 18 Vacuum Relief Regulator is designed for systems that require system vacuum control up to full vacuum.

The Model 18 Vacuum Relief Valve uses a force balance principle to open the relief valve and allow atmospheric air to lower vacuum levels when the set point is exceeded. Stability of regulated vacuum or pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the inner valve in accordance with the flow velocity.

The Model 18 pneumatic vacuum relief regulator features control sensitivity of less than 1/8" water column and a balanced supply valve to deliver consistent and reliable accuracy.

The Fairchild Model 18 will handle a 30 in Hg, 762 Torr, 102 kPa maximum supply vacuum and offers three (3) relief vacuum ranges from 4 in Hg, 140 mBar, 14 kPa, up to 30 in Hg, 1000 mBar, 100 kPa. The Fairchild Model 18 pneumatic vacuum relief regulator offers up to 8 SCFM, 68 m3/hr flow capacity.

FIPA presents: Oval vacuum cups

Introducing the newly developed oval vacuum cups series.

The vacuum cups are characterised by a very long cycle life, which has also been successfully demonstrated against vacuum cups of competitors in practical operation. The long service life is enabled by means of a new high wear- and oil-resistant NBR material and a special vacuum suction cup construction which minimises the load on the vacuum cup during handling.

FIPA presents: New ID grippers for parts with different diameters

Flexible and service friendly

The pneumatically operated, single-acting ID grippers from FIPA GmbH have already established themselves as the alternative for workpieces with holes or cut-outs or for when vacuum cups or grippers aren’t just right for handling goods. FIPA has completely overhauled its portfolio and now offers users maximum flexibility with minimal set-up time.

The small ID grippers are now equipped with food-safe gripper heads made of polyamide (PA) and are suitable for light and small parts with openings measuring 3 to 10 millimeters in size. If necessary, the gripper heads can be easily exchanged in a non-destructive manner.
