Advanced Powered Side Draft Hood Systems
A Powered Side Draft Hood is an advanced industrial fume extraction system designed to capture smoke, fumes, dust, and airborne contaminants directly at their source.
Unlike conventional canopy hoods that rely on natural upward movement of hot gases, a powered side draft hood uses a dedicated high-capacity fan to create a strong directional airflow that draws pollutants horizontally into the extraction system.
By removing contaminants before they spread into the workplace, the system improves air quality, enhances worker safety, and helps industries comply with environmental regulations.
An Efficient Fume Extraction Mechanism: How does it work?
The Powered Side Draft Hood operates on the principle of source capture, where the hood is strategically positioned near the emission point to collect smoke, fumes, and dust generated during industrial processes.
A specially designed axial flow fan integrated within the hood creates a strong suction field that directs contaminants toward the hood opening, while a downstream centrifugal blower connected to a dust collection or filtration system maintains continuous negative pressure throughout the ducting network.
- 1. Hood Fan + Centrifugal Blower – Work together to capture emissions efficiently during charging, melting, pouring, and other operations.
- 2. Induction Furnace Use – Hood can be mounted on a motorized rotating system for precise positioning over fume generation areas.
- 3. Pollutant Conveyance – Captured emissions move through ducting to dust collectors, bag filters, wet scrubbers, or other APC equipment.
- 4. Clean Air Discharge – Particulate matter and contaminants are removed before safe air is released back into the workplace.
Reliable Industrial Fume Extraction Hood Solutions
INDOFAN Powered Side Draft Hoods are engineered for induction furnace applications, providing direct source capture of smoke and fumes. Designed for efficient operation during charging, melting, refining, these systems reduce fugitive emissions and improve workplace air quality.
Our hoods deliver suction efficiency of 80–90%, depending on furnace layout and operating conditions. As part of advanced ventilation systems, they capture fumes at the point of generation, ensuring a cleaner, safer environment and compliance with environmental standards.
Engineered for Continuous Furnace Operations
Unlike conventional canopy hoods that may interfere with furnace operations, the INDOFAN Powered Side Draft Hood is specifically designed to allow uninterrupted production activities.
The hood remains in its operating position during:
- • Magnet charging operations
- • Poker rod manipulation during melting
- • Routine furnace operations
This eliminates the need for frequent hood repositioning, resulting in improved operational convenience, reduced downtime, and enhanced productivity.
Advanced Fume Extraction Solutions: Side Draft Hood
Superior Capture Efficiency
Side draft hood systems capture contaminants at the source, drawing pollutants horizontally across the operator’s breathing zone. Achieves capture velocities of 100–150 FPM with minimal airflow, ideal for welding, chemical benches, and grinding operations.
Built from galvanized steel, SS 304/316, or polypropylene, these hoods withstand aggressive fumes, temperatures up to 250°C, and abrasive dust. Adjustable baffles and sliding openings optimize containment and energy use.
Powered Ventilation Design
Integrated high-static centrifugal blowers deliver immediate negative pressure, capturing smoke, vapors, and fine dust. Available in capacities from 500–15,000 CFM, units mount on walls or floor frames for flexible layouts.
Equipped with spark-resistant construction, fire-rated dampers, and carbon filtration. Blower motors feature TEFC or explosion-proof enclosures, while VFDs enable precise airflow control for advanced ventilation needs.
