Bank of small cyclones in one housing. To 90% down to 20 micron, with hopper and rotary air lock.
Supply and exhaust ventilation, evaporative cooling, roof extractors, jet fans and air distribution.
Butterfly, multi louver, inlet vane, diverter and guillotine dampers in MS and stainless steel.
A fan is named by the job it does. Each duty page states what the fan does, the blade types selected for it, and how it is used in each industry and each process.
| Duty | What it does | Type usually selected |
|---|---|---|
| ID Fan | Sits at the outlet of a boiler, kiln or furnace and draws the flue gas through the plant to the stack. | Backward curved, backward inclined and radial tipped |
| FD Fan | Supplies combustion air to a boiler or furnace, pushing ambient air through the air heater and into the windbox against the furnace draft. | Backward curved and backward inclined |
| PA Fan | Supplies the air that dries the pulverised fuel in the mill and carries it to the burners. | Backward curved and radial tipped |
| Preheater Fan | Draws the kiln exhaust gas through the preheater cyclone stages. | Backward curved and radial tipped |
| Raw Mill Fan | Draws hot kiln gas through the raw mill and separator, drying the raw meal on the way and carrying the fine product to the collector. | Backward curved and radial tipped |
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| High Pressure Blower | Delivers combustion, aeration and conveying air where the system resistance runs to several thousand millimetres of water column in a single stage.. | Backward curved and radial tipped |
| MVR Blower | Recompresses the vapour leaving an evaporator so it can be reused as the heating medium. | Backward curved |
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. | Backward inclined and radial tipped |
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| Roof Extractor | An axial fan in a weatherproof cowl mounted on an inclined or flat roof, exhausting hot air from the ridge of a factory shed.. | Axial |
| HVAC | Supply, return and exhaust fans for heating, ventilation and air conditioning of plant and office space. | Axial, backward inclined and forward curved |
All thirty applications | Fans by process
You send flow, pressure, gas condition and temperature. We confirm the operating point on the fan curve, at the hot condition and the cold start.
Impeller, volute, shaft and drive built as one assembly in the material the gas needs: mild steel, stainless steel, PP-FRP, rubber lined.
Performance tested as per IS 4894, BS 848 Part I or your standard. Rotor balanced static and dynamic, with records.
Performance testing, energy audit, retrofit, rotor replacement, balancing and vibration analysis, condition monitoring, commissioning and after-sales.
Flow, pressure, gas condition and temperature are enough to start a selection.
