Flextraction has delivered
six wall-mounted fume and
dust extraction systems to
Weldability-Sif in Letchworth
Garden City. Flextraction
engineers have installed the
equipment in the foundation
level welder training facility
at Stevenage Skills Centre at
North Hertfordshire College.

The systems have totally selfsupporting
hood positioning
devices (HPDs) with 100mm
diameter flared hoods
equipped with mesh guards.

Flextraction has now
installed in each of the 12
welding bays: 2m standard
telescopic HPDs incorporating
black polyester coated 100mm
diameter PVC 371 hoses with
a coated mild steel 100mm
diameter flared hood and
mesh guard. Each HPD was
supplied fully assembled with
wall mounting bracket, control
damper and with no internal
components. Each bay has an
electronic airflow indicator
attached to each hood to
monitor extraction airflow.
