It is the air speed at the point where contaminant is actually generated. A hood that looks adequate but does not achieve capture velocity at the source lets fumes escape into the room, where the general ventilation system is then left diluting a load it was never sized for. We design the hood around the source, not the other way round.

Industrial Exhaust & Fume Extraction Systems in South Africa
Manufacturer, Supplier & Exporter of Industrial Exhaust Systems for South Africa.
We design and manufacture industrial exhaust fans, fume extraction hoods and flue gas exhaust systems as a complete path from capture point to discharge. Mining, minerals processing, steel and chemical operations need dust and fume extraction built for abrasive and corrosive service. We design capture at source, select duct material against the exposure and size the make-up air path so the system performs to design.
In South Africa, johannesburg / highveld runs at 30-34°C summer with low humidity - strong DEC case and durban / kzn coast at 30-33°C with 70-80% relative humidity, which is why our recommendation for the location is dec inland; idec and hvls on the kzn coast. On that basis, dust and fume extraction for mining and minerals service is designed around abrasion and capture velocity rather than fan size alone. We supply and install across Germiston & Wadeville, Isando & Kempton Park and Rosslyn, Pretoria.
Technical Highlights
- Hot air and flue gas exhaust systems for furnaces, kilns, ovens and boiler houses
- Duct material selected against actual chemical, abrasive and thermal exposure
- Make-up air arrangements sized to the volume being removed
- Roof ventilators and discharge arrangements planned so extract is not re-entrained
Benefits
- Appropriate duct material avoids premature corrosion failure and repeat replacement cost
- Works with evaporative cooling, which can supply the fresh make-up air the extract system needs
- Contaminants and heat are removed where they are produced instead of being spread through the building
Applications in South Africa
- Automotive & auto components – Weld fume extraction at source, paint booth exhaust and general heat removal over hot processes.
- Mining & minerals processing – Dust extraction at crushing, screening and transfer points, plus workshop fume removal.
- Steel, metals & rolling – Furnace and mill exhaust, dedusting and high-temperature extraction with heavy-gauge construction.
- Food, beverage & agro processing – Kitchen, oven, fryer and drying line exhaust with hygienic construction and grease handling.
- Warehousing & logistics – Ventilation exhaust, roof extraction and charging area fume removal for battery and MHE bays.
Working With Us in South Africa
Over 35 years of manufacturing and more than 6,400 completed projects means most of what a site throws up has been seen before, and the design allows for it in advance. We manufacture from our own facilities at Pune, Hyderabad and Tirunelveli, and hold a 4.9 out of 5 rating from 33 Google reviews.
Frequently Asked Questions
What is capture velocity and why does it matter?
How is this equipment shipped to South Africa?
Shipped FOB Nhava Sheva (JNPT) or Mundra to Durban, Cape Town and Ngqura, with inland movement to Gauteng. Export packing is specified for the route and handling conditions, and documentation is prepared as part of the order rather than after it. Spares and consumables are normally shipped with the consignment so a replacement part does not become a separate small shipment later.
Do you provide SABS / NRCS documentation for South Africa?
Yes. We prepare the product technical documentation, test data and declarations needed to support the applicable SANS route including Letter of Authority applications, and we work alongside the customer's appointed conformity assessment body. The certificate itself is issued by the accredited body rather than by the manufacturer, so our role is to prepare and support the file so the consignment is not held at port.
