Plymovent KUA-4/H ATEX Industrial Fume Extraction Arm Hood 4 Meter Length

Plymovent KUA-4/H ATEX Industrial Fume Extraction Arm – 4 Meter Length, Wall/Hanging Mount

The Plymovent KUA-4/H ATEX is an industrial-grade, flexible source-extraction arm engineered specifically for capturing hazardous dust, gases, and volatile fumes directly at the point of generation. Measuring 4 meters (approx. 13 feet) in length, this robust extraction arm combines an expansive working radius with full ATEX certification, making it a critical safety component for potentially explosive atmospheres. Its counterbalanced external knuckle joints ensure effortless positioning, low pressure drop, and easy maintenance in high-demand industrial processing zones.

Technical Performance & Design

• ATEX Zone Certified: Fully approved for use in explosive environments (classified under ATEX Directive 2014/34/EU), featuring complete electrical grounding and anti-static materials to eliminate electrostatic discharge risks.
• External Knuckle Mechanism: Designed with Plymovent's signature externally mounted support joints, keeping the internal airflow path completely unobstructed. This maximizes air conductance, reduces noise levels, and prevents material accumulation inside the arm.
• 360-Degree Universal Hood: The hood assembly features a double ball bearing race that allows for smooth, omnidirectional rotation, enabling precise alignment with rising thermal plumes or erratic fume streams.
• Spring-Counterbalanced Arm: The heavy-duty internal spring support system allows the operator to position the 4-meter arm with minimal physical effort, ensuring it stays securely in place once positioned without drifting.

Product Specifications

• Arm Diameter: 160 mm (approx. 6.3 inches)
• Hose Material: Flame-retardant, anti-static polyurethane reinforced with a conductive steel wire helix
• Exhaust Hood Diameter: Expanded geometric profile for optimal capture velocity
• Recommended Airflow: 800 – 1200 m³/h (approx. 470 – 700 CFM)
• Mounting Type: Wall bracket or stanchion suspension (Hanging model)

Key Benefits & Applications

• Combustible Dust & Solvent Extraction: Essential for capturing fine particulate matter in powder handling, chemical dispensing, and pharmaceutical batching processes where explosive mixtures may form.
• High-Capacity Workspace Coverage: The 4-meter reach provides an extensive hemispherical working zone, making it ideal for covering large assembly benches, pilot scale-up reactors, or multi-station welding setups.
• Volatile Vapour Mitigation: Safely vents flammable solvent vapors, chemical gases, and toxic airborne contaminants away from the operator's breathing area directly to central filtration systems.
• Low Maintenance Operation: Because the mechanical linkage is external to the exhaust stream, the arm requires significantly less cleaning and prevents mechanical component corrosion when extracting aggressive chemical media.
