In each industry
Chemical & Pharma
Chemical plants exhaust corrosive fumes from reactors, dryers and storage into wet scrubbers, with fans in stainless steel, PP-FRP or rubber-lined construction. Pharma plants add clean-room supply through AHUs with pre, fine and HEPA filtration, and solvent recovery through adsorption towers. MVR blowers recompress vapour on evaporators and effluent plants.
Food Processing
Food plants need stainless steel fans for dryer and oven exhaust, dust extraction on milling and mixing with bag filters, and ventilation and AHUs that hold the processing area at the required temperature and air quality.
Automobile
Vehicle plants use fans on paint shop supply and exhaust, on ovens and dryers, on welding fume extraction, and for plant ventilation. Paint booth exhaust goes through wet scrubbers or adsorption towers for solvent; oven exhaust needs a hot air fan; the body shop needs fume extraction into bag filters.
Nuclear
Nuclear facilities use ventilation systems that hold the building under controlled negative pressure, with HEPA-filtered exhaust and AHUs on the supply side. Fans are specified for reliability and for filtration efficiency rather than for dust or heat.
By process
The same duty, selected for the gas of each process.
