Centrifugal, axial, roof and inline fans built to a duty point, not a catalogue page.
Send us the airflow, the static pressure and the temperature, and we will size the
impeller and the motor around them.
Centrifugal, axial, roof, inline, explosion-proof and air curtain. Every unit is quoted against a duty point, with the fan curve and the sound power level attached.
Send the airflow, the static pressure and the air temperature. We will come back with the operating point on the curve, the absorbed power and the sound data.
The same impeller is built four different ways depending on the air it has to move and what that air is carrying.
01
Tunnels and underground works
Long duct runs, high system resistance and a jet or booster fan sized for the worst case rather than the average. Casings are specified for the drive length and the temperature the tunnel actually reaches.
02
Food and beverage plants
Washdown-ready casings, stainless or coated impellers and bearing arrangements that survive daily cleaning. Air changes are sized against the process load, not the room volume alone.
03
Process and chemical
Corrosive and solvent-laden extract, with material and coating selected against your gas analysis. Where the atmosphere is classified, we build to the equipment category your assessment names.
04
Commercial and industrial buildings
Roof extract, car park ventilation, kitchen extract and door air curtains, sized to a duty point and quoted with a sound power level for the position it is measured in.
How we work
From a duty point to a fan that holds it
01
Size
Send the volume flow, the static pressure, the air temperature and the density at your altitude. We place the duty point on the fan curve and tell you where it sits relative to peak efficiency.
02
Build
Impellers are welded, then dynamically balanced on a two-plane machine. Casing material, coating and shaft seal are chosen against the gas, the dust load and the temperature, not against a default.
03
Test
Aerodynamic performance is measured on a ducted test rig following the ISO 5801 method, and vibration is checked at the operating speed. The measured points are recorded against the serial number.
04
Support
Impellers, bearings, shaft seals and motors stay available for the life of the model. Replacement parts are matched to the serial number so a superseded impeller is caught before it ships.
What you get
Four commitments that outlive the order
01
Duty point first
Airflow, static pressure, temperature and altitude reviewed before a fan size is proposed.
02
Balanced and measured
Every impeller is dynamically balanced and every unit is run at its operating speed before it is crated.
03
Curve with the quote
The fan curve, the absorbed power and the sound power level are supplied with the offer, not after it.
04
Parts for the life
Impellers, bearings, seals and motors held for as long as the model is in service, matched by serial number.
The fan runs where the fan curve crosses the system curve, not where the catalogue extract says it does.

Tell us the duty point. We will tell you the fan.
Airflow, static pressure, air temperature and how the fan is ducted. You will get a
sized model, the operating point on its curve and the sound data for it.
