A local extractor with friction joints
for worksites where great flexibility is
required.
The TERFU is a local extractor with friction joints
designed for use in workplaces where great
flexibility is required e.g. laboratories, production
environments, and lighter industrial applications.
Simple, easy function.
The friction joints have a large frictional diameter
and are supported with ball bearings. The degree
of friction is easily adjusted with a one-hand knob.
Adapted support springs balance out the weight of
the arm. All arms are equipped with a 360 degree
rotational swivel mounted in place. An air tight
damper is fitted as standard.
Always easy to select the right product.
Terfu is available in two versions:
– Standard version. Suitable for evacuation of
most types of airborne contaminants.
– PP version. Most suitable for evacuation of
highly corrosive contaminants in high
concentrations.
All sizes are suitable for table mounting, ceiling
mounting and wall mounting.
The same suction arm is used for suspended
mounting from ceilings and walls.
Ceiling and wall brackets both consist of an
anodized square aluminum profile for durable
surfaces and high stability.
All ceiling brackets are available in eight standard
lengths up to 80 inches. Longer lengths can be
supplied by special orders.
To further simplify your mounting and provide a
cleaner look, an MTI CT escutcheon plate can be
used to cover rough cut holes in the false ceiling.
The TERFU system is design protected with several
patents- and design protections pending.
The Movex range also includes fans, accessories, automatic controls and filters suitable for local extraction.

TERFU Model
Standard version of Terfu with polypropylene joints
and anodized aluminum tubes.
The standard version of Terfu is suitable for evacuation
of most types of airborne contaminants from
laboratories, schools, hospitals, pharmaceutical
industry, nail salons and light industrial applications.
Polypropylene(PP)version of Terfu with joints and
tubes in recyclable PP. All metal parts that come in
contact with the airstream are made from acid
resistant stainless steel (SS 2343).
The PP version of Terfu is primarily used for
evacuation of extremely corrosive contaminants in high
concentrations for certain laboratories, pharmaceutical
and chemical industries.
When using a ceiling mounted PP extractor, recommend using an MTI ceiling bracket with internal and
external powder coating.
TERFU Maximum flexibility
Terfu joint. The large frictional diameter together with
the single grip adjusting knob provide a rigid, stable
joint with a smooth easily adjustable function without
requiring the application of excessive force or tools.
The joint has reinforced side pieces. Ball bearings that
isolate the adjusted friction level allow the arm to
move up and down without locking the joint or loosing
stability and function.
Appealing stable brackets
All Terfu extractors have a standard full-swivel that
allows 360° of rotation without the need for special
sleeves or double wall mountings. Both ceiling and wall
brackets consist of a special anodized aluminum
profile that provide an appealing, functional
installation. The ceiling bracket also acts as the
extraction channel, thus avoiding the need for
expensive external channeling and additional holes in
the finished ceiling.
Installation is simple and stable. The ceiling bracket
is available in eight standard lengths from 10 to 80
inches. Lengths greater that 80 inches can be supplied
to order. The ceiling mount can be provided with internal epoxy coating for use in aggressive environments.
