Overview
What is a Fume Extraction System?
Bharti Enviro designs and installs fume extraction systems for welding bays, chemical reactors, and industrial process vessels — combining downdraft tables, canopy hoods, on-gun extractors, and lateral suction slots to capture hazardous fumes before they enter the operator's breathing zone. All systems are designed per ACGIH industrial ventilation guidelines and include appropriate filtration to meet CPCB stack-emission norms.
Key Features
- On-gun extraction captures ≥ 85% of welding fume at source before workplace dispersion
- Downdraft bench and side-draft booth configurations for benchtop operations
- Cartridge filter with HEPA stage achieves outlet < 1 mg/Nm³ total particulate
- Fan selection matched to hood capture velocity ≥ 0.5 m/s at furthest source point
