2.3. AUTOMATIC CONNECTORS WITH EXPANDABLE JOINTS
ATEQ automatic connectors are used so that accurate and reliable assemblies can be
built to check air tightness. They simplify the work of the operator as they are self-
locking thanks to the use of a pneumatic valve supplied from the mains compressed air
supply. Several connectors may be controlled by the same remote, powered by an
ATEQ or another logic.
They adapt easily 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 either in anodised aluminium or stainless steel as standard. Different types of
joints are available depending on the elasticity required.
2.3.1. Operation
The connector is positioned manually or automatically using a jack or cylinder.
Compressed air is allowed 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.
2.3.2. Standard dimensions
SAG and SIG have been designed for threaded and tapped caps. For the time being,
they are available in gas norm. Sizes, which are: 1/2", 3/4", 1", 11/4", 11/2", 2", BSP.
The SA and SI are designed for smooth nozzles, 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.
