ball-bearing jointed extraction arm
- Standing (KUA-S)
KUA - Standing
The PlymoVent ball-bearing jointed extraction arm – KUA-S – is a flexible and
efficient extractor for dust, welding fumes, soldering fumes, oilmist, fumes from
solvents etc. Ideal for many problem areas. The outer and inner arm are coupled
by an externally mounted elbow joint for which we have a patent application pen-
ding. This external joint is adjusted by hand without the need for any tools. The
lower spring-assisted joint supported in a double ball-bearing mount, gives KUA-S
a smooth, flexible movement. The KUA-S reaches above its mounting height and is
manoeuvrable through 360°. Both outer and inner arms are made of light, smooth
aluminium tubing. This not only makes the arm rugged but also minimises the total
weight and noise level, even at high extraction rates.
Delivery
The arm is delivered complete with mounting flange.
Advantages
• Easy to move thanks to the ball-bearing mountings and spring assistance.
• Inner and outer arms made from aluminium tubing give increased
mechanical strength.
• External, middle joint simplifies adjustments.
• Easy-to-reach ring handle ensures simple positioning of the hood.
• Standard stanchion for ceiling, floor and wall mounting makes
installation easy.
• Reaches up to 6 m with stanchions PA-110 or PA-220.
• Rugged construction.
