Dust & Fume Extraction & Control Specialists
We offer a comprehensive range of air movement systems.
Situations addressed include:
Dust extraction from various working environments
This may be dust that presents a hazard to health, or dust
that must be removed for product quality purposes.
Hazardous dust extraction & collection
Some of the situations we have developed solutions for:
|
|
- During the shot blasting process, dust particles are dislodged.
These particles may contain silica or other carcinogenic materials.
It is necessary to separate the contaminants from the shot so
that it may be re-circulated and re-used.

 In
paint manufacture, a range of pigments of a highly hazardous nature
are often used to produce surface treatments for aggressive environments
such as ships hulls and off shore plant used in oil and gas production
and exploration. Dust from the process must be captured and disposed
of in a highly controlled manner.
Dust issues in product quality
- Removal of surface dust from car bodies prior to final coat painting.
We have recently produced a bespoke solution for a UK production plant.
Dust must be removed from the irregular surfaces of the body and yet
a single solution is required to treat cars of all sizes. High velocity
air streams are involved but stringent noise level controls are in place.
The solution devised involves the use of a system of air knives and
air cannon arranged around the profile of the vehicles to ensure that
surfaces are thoroughly treated. Detailed work was done on a pilot scale
prior to final design to ensure that the installation met the brief
but was not over-specified. This enabled us to minimise both the initial
investment cost and the running costs of the process.
- In paint manufacture, dust is extracted during the micronisation
process in order to classify the particles on the basis of size for
product quality purposes. We developed a system to facilitate the classification
with the residual dust being separated for disposal.
Fume exhaust systems
 One
of our more challenging projects was extracting fumes from a steel
profile burning process. Here we must capture fumes from a travelling
fume source, the burning torch, as it moves across the whole area
of the 4 x 20 metre profile burning table. To accomplish this
we developed a matrix of hoods across the width of the table.
A series of dampers and limit switches direct the extraction to
the immediate cutting zone. Along the length of the table we placed
a lip extraction duct which is connected to a travelling burner
head carriage. This permits extraction at any point along the
length of the table.

- These images show the lip extraction duct and travelling burner
head carriage which are described above, in a different application.
Here they are being used to deal with vehicle exhaust fumes in
the manufacture of heavy plant such as earthmovers and cranes.
The outlet can be used at any point along the carriage, to suit
the location of the parked vehicle.

Other examples of the environments in which we develop solutions to
fume exhaust problems are chemical process tanks. Here our installations
cope with hazards such as solvent fumes and steam exhaust.
Bespoke extraction solutions
Our business relies upon us developing imaginative solutions to very
challenging situations. Below is an example of such a situation.
 In
the steel forging of components, oil and graphite are used as lubricants.
As a result of the high temperatures in the forging process, residues
are driven off in the form of dust, fumes and steam. These are collected
in a unit incorporating specially designed filter pads irrigated with
an oil. The oil absorbs the residues and is combined with the pads in
a highly efficient process to scrub out the fumes and particulate matter.
If you are faced with a difficult situation and perhaps others have
tried and failed to provide a totally effective solution, please give
us a call. We have been presented with very few challenges, in our field,
that have beaten us.
