The process
Curing presses release rubber fume at opening. Hoods over the presses take the fume to a scrubber or filter, and the curing hall needs heavy ventilation for the heat.
The gas at the fan
Rubber fume from curing presses condenses as a tacky film. The fan is in the exhaust after a scrubber or filter, with a wheel that can be cleaned and a casing with access doors.
Selection for this duty
| Construction | Axial fans in weatherproof cowls, or supply and exhaust units with filters as the air quality requires |
| Density at the fan | At about 80°C the gas density is close to 1.00 kg/m³, 83% of standard air. Pressure developed and power drawn fall in the same ratio, so the selection is made at this density and the motor is checked at cold start. |
An axial fan in a weatherproof cowl mounted on an inclined or flat roof, exhausting hot air from the ridge of a factory shed. Client-stated blade types for the Roof Extractor in general: Axial.
