Details:

The Fairchild 20 Pneumatic High Capacity Volume Booster uses a pneumatic input signal to accurately control output pressure. A balanced supply valve minimises the effects of supply pressure variation.

Features

  • An Aspirator Tube compensates downstream pressure droop under flowing conditions.
  • Optional Adjustable By-Pass Needle Valve allows tuning for optimum dynamic response (1:1 ratio only).
  • Optional Fixed Negative Bias allows operation with pneumatic devices that cannot be adjusted to zero input pressure.
  • A separate Control Chamber isolates the diaphragm from the main flow to eliminate hunting and buzzing.
  • Unit construction allows servicing without removal.
  • Mounting Bracket available.
  • Canadian Registration Number (CRN) Certification for all territories and provinces.

Operating Principles

The Fairchild 20 Booster is a pneumatic device capable of high flow and exhaust capacity. This device uses a force balance system to control the movement of the supply and exhaust valves.

At set point, the force due to signal pressure that acts on the top of the Upper Diaphragm balances with the force due to output pressure acting on the bottom of the Lower Diaphragm.

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.
