2.9. AUTOMATIC CONNECTORS WITH EXPANDING JOINTS
ATEQ automatic connectors are used so that reliable, accurate assemblies can be built
to check air tightness. The operator's task is simplified because these connectors are
self-locking by use of a pneumatic valve supplied from the compressed air network.
Several connectors can be controlled by the same unit, powered by an ATEQ or other
logic.
They can easily be adapted to a large number of fittings and apertures of varied
dimensions. Their use ensures that non-machined walls can be guaranteed airtight.
There are four basic versions of ATEQ automatic connectors :
9 SA for external connections,
9 SI for internal connections,
9 SAG and SIG for threaded and tapped connections.
They are available as standard in anodised aluminium or stainless steel. Different types
of joint are available depending on the elasticity required.
2.9.1. Operation
The connector is positioned manually or automatically using a jack or cylinder.
Compressed air passes through the control aperture via a three part valve. The
pressure pushes the cylinder which squashes the connector. The air tightness is
therefore perfect and there will be no leakage in the connector seals.
2.9.2. Standard dimensions
SAG and SIG have been designed for threaded and tapped connections. They are
currently only available as gas thread, i.e.: 1/2", 3/4", 1", 11/4", 11/2", 2", BSP.
The SA and SI are designed for smooth connections with dimensions from 3 to 80 mm
for the external diameters (SA), and from 10 to 75 mm for the internal diameters (SI).

ILTRATION KIT
Clean, dry air must be used to ensure the reliability of the instruments.
The filtration kit is connected to the air input on the rear panel of the instrument.
It consists of a dust-filtering cartridge (5µm) and another cartridge (0.01 µm) giving
residual oil pollution equal to 0.01 ppm.
