Fiberglass extraction hood is an FRP/GRP ventilation component used to capture and remove airborne contaminants at the point of generation. It is manufactured from fiberglass reinforced plastic and is commonly used in industrial ventilation systems, laboratories, and process environments where corrosion resistance and dimensional stability are required. Performance depends on resin system, hood geometry, airflow design, and duct integration.
Product Definition
A fiberglass extraction hood is a localized exhaust hood manufactured from fiberglass reinforced plastic (FRP/GRP). It functions as the primary capture point in an industrial ventilation system, directing contaminated air into ducting when connected to an exhaust fan. The hood is supplied as an FRP component with optional flanged or direct duct connections, and can be produced in custom dimensions and wall thicknesses based on project requirements.
Key Product Facts
Material: Glass fiber reinforcement embedded in a thermosetting resin matrix.
Product form: Localized exhaust hood for industrial ventilation systems.
Connection options: Flanged or direct duct connections.
Mounting configurations: Wall-mounted, ceiling-mounted, or equipment-mounted.
Customization: Dimensions, wall thickness, and connection interface can be tailored to project requirements.
Material & Construction
The hood is made from glass fiber reinforcement embedded in a thermosetting resin matrix. Resin system selection depends on chemical exposure and service conditions. Common FRP resin systems include isophthalic polyester and vinyl ester.
Internal surfaces can be supplied with a smooth finish. An optional protective gel coat can be supplied for additional surface protection in aggressive environments.
Connection options include flanged or direct duct connections. Mounting configurations can be wall-mounted, ceiling-mounted, or equipment-mounted depending on installation requirements.
Applications
FRP extraction hoods are commonly used in industrial ventilation systems where corrosive fumes, chemical vapors, or high-humidity conditions are present. Typical application areas include:
Chemical manufacturing and processing facilities
Electroplating and surface treatment operations
Pharmaceutical production environments
Industrial and research laboratories
Wastewater treatment and odor control systems
General manufacturing with localized exhaust needs
These are typical industry environments where FRP extraction hoods are used. Actual product suitability depends on project-specific evaluation of chemical exposure, airflow requirements, and operating conditions.
Selection Considerations
Selection of an extraction hood depends on several variables, including contaminant type, airflow rate, duct size, mounting location, and chemical exposure conditions. The following factors are typically considered during project evaluation:
Resin system: Selected based on chemical compatibility and service temperature.
Hood geometry: Determined by capture distance, source type, and available space.
Connection interface: Flanged or direct duct connection based on existing ductwork.
Mounting configuration: Wall, ceiling, or equipment mounting based on installation layout.
Performance depends on proper positioning, airflow design, and integration with the overall ventilation system. Airflow rates are typically determined by contaminant characteristics and hood opening geometry.

FAQ
Q1: Is a fiberglass extraction hood suitable for corrosive industrial exhaust?
FRP construction is commonly used in ventilation components for corrosive environments. Suitability for a specific chemical stream depends on the resin system and expected exposure conditions. Chemical compatibility should be confirmed for the intended service environment.
Q2: Can the hood be adapted for different duct sizes?
Custom dimensions and connection interfaces can be supplied based on project requirements. Final compatibility is reviewed during order confirmation.
Q3: Does the hood require special maintenance?
Maintenance requirements depend on the operating environment and exposure conditions. Regular visual inspection is recommended. GRP surfaces typically do not require protective coatings under normal conditions.
