VAC 20 and VAC 12
Low operating costs, efficient and reliable.
A VAC unit is the right choice for high vacuum extraction of
welding fumes, dust from sanding and grinding operations and
general clean up applications.
VAC systems, a cost effective solution for better working
environment, is based on a powerful vacuum unit, a modular design
dust collector and a modern control unit/starter.
A VAC unit is the perfect extraction source:
• When a large number of working stations require dust extraction.
• When you need a flexible solution matching an expanding
production.
Adaptable
VAC units are available in several sizes. 8-40 extraction points
can be in operation at the same time, served by one single unit. If
you need more extraction points, any capacity can be achieved by
parallel connection of two or more units.
Reliable
VAC units are protected from overload by a flow restrictor and VAC
20 is fitted with an overheat protection.
Low operating costs
VAC units are designed for use in modern systems with automatic
vacuum valves. This means that the air flow can vary rapidly from
max flow to zero. The power consumption adapts to the present
need. The VAC unit comes to a complete stop when not used, thanks
to the automatic start/stop function (option).

VAC systems for multi purpose use
A VAC system with swing arms and automatic vacuum valves
is a professional solution for dust extraction from sanding
operations and for floor or bench cleaning.
In the work shop, a VAC system can serve many different work
stations with the extraction of grinding dust, welding fumes and
factory cleaning.
• Prevents the dust from spreading in the work shop. Desirable for a clean
production and a good working environment.
• On-tool high vacuum extraction during cutting and trimming of composites
eliminates the dust before it can spread in the premises.
• Workplace cleaning can be carried out in an effective and environmentally
friendly way. Floors, work benches, ventilation pipes, filters and other work
spaces are easy to keep clean with high vacuum extraction.
• Welding fumes will be extracted where generated. The on-torch extraction
follows the operator’s every movement.
• Also suitable for other purposes like removing flour dust in bakeries, foam and
dust in textile industries, industrial chemicals etc.
