Introducing BOFA’s new ADVANTAGE range of Laser Fume Control Technology; incorporating our unique,
deep mini pleat 2 stage pre filtration design. Most companies see laser fume extraction as a necessary evil,
required to protect both the laser optics and the health of their operatives. With this in mind, our design
philosophy is:
The vacuum pump is at the heart of the unit and all BOFA extractors are
fitted with continuously rated pumps with a minimum life expectancy of
30,000 hours. This enables us to offer a 3 year warranty on all our laser
extraction units. This warranty is backed up by our pump suppliers, giving
you the added reassurance that BOFA systems are the most reliable on the
market. Comprehensive training and support is also offered to both OEM’s
and end users.
A full range of unit and filter monitoring options are available to suit your
specific requirements (see unit data sheets). Airflow path gives maximum
filter life but also ensures that all particulate is held in the filters. The de-
sign of the unit is such that the exhausted air is blown into a sealed silencer
box. This totally isolates any potentially explosive fumes from being blown
around the electrical equipment. This is critical even when gas sensors are
used as a foolproof precaution.
Filter change is simply a case of opening the door at the rear of the unit and
replacing the used filters with clean ones. Simple controls or alarms, either
visual or direct to the laser, indicate the need for filter replacement.
Much of our design criteria is focused on our customers need for cost
effective equipment. Our standard units offer many options for turnkey
solutions. This enables the customer to purchase only the options that they
require.
Low consumable costs are a big benefit for customers choosing Laser coders
over inkjet. Many extraction systems have extremely expensive replacement
filters making for very high annual running costs. BOFA have the highest
capacity and by far the lowest cost filters available on the market.

ADVANTAGE 2 STAGE PRE FILTER
Most ADVANTAGE units are fitted
with the new concept Deep Mini Pleat
pre-filter as standard. This unique
filter gives a staggering 12m² of media
surface without compromising the
efficiency, which remains at 95%.
Contaminated air enters the system
through a 50mm, 75mm or 400mm
inlet and is instantly expanded in the
large pre filter chamber, causing the
velocity of the air to drop. The effect of
this causes the larger particulate to rest
gently on the surface of the filter, rather
than hit it at speed, lodging within the
filter media. Once the particulate has
built up and got heavier, gravity breaks
it away from this filter, thus extending
its life. Breakaway particulate is
captured within the filter box.
HEPA FILTER
All BOFA HEPA filters are manufactured
by specialist filter companies to our
specification. This ensures that the
latest manufacturing and testing
techniques are used. Each filter
incorporates a series of bonded webbing
between the pleats. This feature not
only guarantees even spacing between
each pleat, but also alleviates the
possibility of airflow vibration or
collapse. Filters are individually tested
and certified to a minimum efficiency of
99.997% down to 0.3 microns and 95%
as small as 0.1 microns.
CHEMICAL/GAS FILTER
The standard chemical filter contains a
multi purpose media to give protection
against the large range of VOC’s
(volatile organic compounds) generated
when lasering a wide range of organic
materials. Additionally we can offer
a variety of other medias to fine tune
the selection for particularly arduous
applications.
FILTER REPLACEMENT
Filters can be replaced quickly with
ease and safety. Each new filter comes
with a resilient neoprene gasket
fitted. This ensures that there is no
filter bypass caused through re-using
existing potentially torn or perished
built in seals.
UNIT & FILTER MONITORING
SYSTEM
Each ADVANTAGE unit is fitted with
a continuous monitoring system. 3
coloured LED’s on the front of the
unit tell the user of the condition of
filters within the system. A green light
indicates that the filters are clean;
amber when filters are getting close to
replacement and red when filters are
blocked and requiring changing. The
green LED also indicate that the unit
is running and all 3 LED’s will flash if
there is a fault with the system.
FEATURES
Most of the Advantage units can be
constructed from either Stainless
Steel or Powder Coated Mild Steel. The
Stainless Steel fabrication is suitable
for wash down facilities such as high
speed PET bottling lines. The Powder
Coated Mild Steel version is not
suitable for applications where water
is present.
