Industries served
The duty, not the sector, decides the machine. But each industry brings its own gas, its own dust and its own tolerance for downtime, and those three things are what we design against.
Read this first
Three questions per sector
What is in the gas, what is the fan allowed to do when it fails, and how long a shutdown is available. Every one of the notes below is a variation on those three questions.
Sector
Cement
Kiln and cooler auxiliary fans, separator and bag filter duty, and material transfer. Hot gas, alkaline dust, and an almost total intolerance for unplanned stops because the kiln is the constraint. Expect radial and shrouded exhauster wheels, hard-faced and lined, with wear parts held as stores.
Typical wheels
High pressure radial blade, radial shrouded exhauster, high temperature plug build where the gas runs hot.
Sector
Chemical and petrochemical
The gas is the specification. Chlorides, sulphur compounds and acid carryover make material selection the first decision, not the cost line, and a mild steel fan in that service will be a maintenance item within a season. Duplex 2205, SS 316L, FRP and titanium all appear in our build history here.
Typical wheels
Backward curved and backward inclined in stainless, air handling exhausters in corrosion-resistant grades.
Sector
Fertilizer
Ammonia and urea duty is corrosive and often hot; granule transfer is abrasive. Both appear in the same plant, so the material list and the wear list are both long. Cleanliness and containment drive casing design and seal choice.
Typical wheels
Backward inclined and radial wheels in stainless, exhausters on process vent duty.
Sector
Energy and power
Forced draft, induced draft, secondary air and flue gas transfer on boilers and furnaces. High temperature, fly ash and continuous duty together: the fan is an auxiliary that the plant cannot run without, so the design brief is reliability plus a documented spares list.
Typical wheels
Radial shrouded exhauster, high temperature plug blower, backward inclined on FD air.
Sector
Railways and infrastructure
Tunnel, shed, station and depot ventilation: high volume against modest pressure, often in a damp and gritty atmosphere, usually with a control interface and an emergency mode specified by the project rather than by us.
Typical wheels
Axial flow fans and air handling exhausters, with corrosion protection and reversible duty where required.
Sector
Water and effluent treatment
Aeration, backwash, chemical dosing air and biogas transfer. Depth converts to pressure, standard-air rating hides the density correction, and the plant is usually noise-sensitive because operators work next to the blowers.
Typical wheels
Air handling exhauster and backward curved builds; stainless or coated where the gas is biogas.
Sector
Food and beverage
Hygiene drives the design: stainless wetted parts, continuous welds, cleanable geometry and no crevices. Steam, sugar dust and organic acid are each a problem in their own way, and wash-down means the fan gets hosed.
Typical wheels
Backward curved and backward inclined in SS 304 or SS 316L, with a finish spec agreed up front.
Sector
Pharmaceuticals
Process air, dryers, granulation and extraction in controlled areas. The documentation is often as demanding as the machine: material certificates, surface finish, and a build that fits a cleanable room rather than a plant yard.
Typical wheels
Backward curved and backward inclined stainless builds, make-to-order where the room is the constraint.
Sector
Pulp and paper
High volume extraction, often wet, warm and loaded with fibre. Fibre wrapping around a shaft is a real failure mode, so seal design and access for cleaning matter more than peak efficiency.
Typical wheels
Air handling exhauster and radial exhauster builds with attention to inlet and seal geometry.
Sector
Automotive
Paint booth extraction, oven circulation, workshop ventilation and test rigs. Volume is large, control is tight and the process is continuous, so a booth fan is judged on uptime, cleanability and noise as much as on its curve.
Typical wheels
Backward inclined and air handling exhauster; drive arrangements chosen for area classification.
Sector
Environmental and pollution control
Bag filters, cyclones, scrubbers and odour control. Our own pollution control equipment and the fan are usually one system, which means the fan is selected against the filter and the scrubber together rather than as a separate item.
Typical wheels
Backward inclined on clean side, radial and shrouded exhausters on dirty side, stainless where scrubber gas is wet.
Sector
Process and drying
Dryer and cooler air handling, often with our paddle or sludge dryer. Hot, moist and sometimes sticky, and the fan has to hold its duty while the process moves between products.
Typical wheels
Backward inclined and high temperature builds; make-to-order where the dryer package dictates the geometry.
Sector
General manufacturing and workshops
Weld fume, machining mist, extraction hoods, roof ventilation and conveying of swarf or light product. Modest duties, delivered often, and the best value comes from a standard build with a sane margin.
Typical wheels
Backward curved, backward inclined and axial flow fans.

Sector alone is enough for us to ask the right questions. Add the airflow, pressure and temperature and we can usually come back with a selection on the same day.
