Épuisement local Hood
Wall-mounted positionable local exhaust hood with a 160 mm corrosion-resistant articulated arm, external anodized supports, 360-degree swivel and integrated damper for source capture of compatible fumes and vapors.
- Capture hood positions close to the emission source
- Articulated arm rotates and holds its working position
- Corrosion-protected components suit compatible chemical areas
Introduction de produit
The Local Exhaust Hood is a positionable capture device for removing compatible fumes, vapors and light non-combustible airborne contaminants near the point of release. A wall-mounted swivel connects to a 160 mm flexible white hose supported by two external anodized-aluminum arm sections and three friction joints. The circular bell hood can be tilted around the source, while an integral damper provides local airflow adjustment. The displayed 3 m arm is intended to connect to a separately sized exhaust fan, duct and treatment system. Effective capture depends on hood distance, source momentum, cross-drafts, arm pressure loss and the airflow available at the connection.
Key Features
A 360-degree wall swivel lets the arm serve a broad area around one mounting point
Two articulated support sections and friction joints hold the selected position without a floor stand
External anodized-aluminum supports remain outside the extracted air path and receive added corrosion protection
The smooth 160 mm flexible hose bends with the arm while maintaining a defined circular flow path
A tilting bell hood can be aimed toward rising vapor, light fume or a localized release
An integrated damper allows local balancing without adding a separate loose valve at the hood
The wall bracket provides a clear round connection to fixed exhaust ductwork
Several arm lengths allow reach to be matched to the bench, vessel or equipment position
Hood light and fan-switch accessories can be added without changing the basic source-capture function
Préoccupations du client produit
Local exhaust succeeds only when the hood stays close enough to the source and the connected system supplies adequate airflow. Position, cross-drafts and contaminant behavior can matter more than the nominal duct diameter.
Capture falls rapidly when the hood is moved too far from the releasePosition the hood as close as the task allows and arrange the work so the contaminant moves toward, not past, the opening.
Room supply jets, doors or operator motion can deflect fumes away from the hoodReduce cross-drafts at the workstation and place the hood on the downstream side of predictable contaminant movement.
A long or sharply bent arm can add enough pressure loss to reduce the intended airflowInclude the selected arm position, flexible hose, duct and damper in the fan and system-resistance calculation.
Friction joints can drift if the arm is overloaded or not adjusted for the hood weightMount the bracket on a suitable structure, balance the joints and keep unsupported accessories within the arm's intended configuration.
Condensable or aggressive vapor can attack the hose, hood, seals or downstream ductConfirm the complete material path for the expected chemical and temperature, and use a different capture product where compatibility is uncertain.
A local hood can spread contamination if it is used for combustible dust or hot material outside its design boundarySeparate combustible, high-temperature and reactive hazards and choose a capture system specifically rated for that service.
Les applications typiques
Localized chemical weighing, transfer and bench-top preparationPharmaceutical and clean-manufacturing workstations with intermittent compatible vapor releaseLaboratory soldering, bonding and solvent-cleaning tasksBattery, electronics and materials-development benchesFood and chemical production sampling points requiring a positionable hoodMaintenance activities where a fixed enclosure cannot reach the emission source
Paramètres techniques
The displayed basis is one indoor 3 m corrosion-resistant extraction arm with a 160 mm smooth flexible hose, two anodized-aluminum external support sections, three adjustable joints, one 360-degree wall swivel and one tilting circular hood with an integral damper. The manufacturer's published arm family uses 700-1000 m³/h recommended airflow and a maximum 70°C fume temperature for the referenced design. The fixed ten-row table uses panel labels; its dimensional rows describe hose diameter, hood span and reach rather than wall-panel dimensions.
