The main dimensions of the fume hood are widths of 1200mm, 1500mm, and 1800mm, with a height of 2350mm. The primary structure of the ventilation hood includes:Cabinet (Body): The cabinet can be constructed from materials such as steel, wood, PP, PVC, stainless steel, etc., based on usage requirements.
Worktop: Resistant to corrosion, acids, alkalis, and high temperatures. Various materials, such as compact laminate, epoxy resin, or ceramic, can be selected based on different experimental requirements for high-temperature or strong acid-alkali operations.
Sliding Doors: Transparent tempered glass doors mounted on the surface of the cabinet keep users away from harmful chemicals and gases. Simultaneously, these doors direct harmful gases into the internal ducts of the ventilation hood.
Deflector Plates: These control the shape of airflow passing through the ventilation hood, reducing turbulence or backflow generated by irregularities and enhancing operational efficiency (may affect noise and static pressure).
Airflow Collection Ring: Located at the top of the ventilation hood, it directs the gases from the hood for exhaust, significantly influencing the efficiency and noise of the ventilation hood.
Airflow Control Valve: An accessory component of the ventilation hood used to adjust the exhaust volume and optimize the surface airflow velocity.
Accessories: Include water taps, sockets, and cups.
Characteristics of Different Fans:
Axial Flow Fan:
Characteristics: Low power consumption, low operating costs, high noise levels, and relatively low suction force (low pressure). Suitable for simple systems and typically installed on walls or pipelines.
Centrifugal Fan:
Characteristics: High power consumption, higher operating costs, elevated noise levels, and a substantial suction force (high pressure). Suitable for complex systems, primarily installed outdoors or on rooftops. For ventilation systems with specific requirements, variable frequency drives and precise control instruments

FAQ
Q: What criteria and standards should laboratories adhere to when selecting and installing fume hoods to ensure compliance with safety regulations and industry best practices?
A: Laboratories should follow established safety standards, such as ASHRAE 110 and SEFA 1, and consider factors like face velocity, containment performance, and exhaust requirements to ensure proper fume hood selection and installation.
Q: In the context of laboratory ventilation, how do containment performance testing methods differ for ducted and recirculating fume hoods, and what are the implications for overall laboratory safety?
A: Containment performance testing for ducted fume hoods typically involves face velocity measurements and tracer gas testing, while recirculating hoods may undergo additional filter penetration tests. Understanding these differences is crucial for maintaining safe laboratory environments.
Q: Can you elaborate on the impact of fume hood design parameters, such as face velocity and sash height, on the effectiveness of fume containment and worker safety, and how these considerations vary for different applications within the laboratory?
A: Face velocity and sash height significantly influence fume containment. Maintaining optimal face velocity ensures proper containment, while adjusting sash height impacts worker exposure. These considerations vary based on specific applications, with different experiments requiring tailored fume hood configurations.
Q: With the increasing emphasis on sustainability in laboratory operations, what innovative features or technologies are being integrated into modern fume hood designs to optimize energy efficiency without compromising safety standards?
A: Modern fume hood designs incorporate features such as variable air volume (VAV) controls, occupancy sensors, and energy-efficient fan systems to optimize energy usage. These innovations enhance sustainability while maintaining stringent safety standards.
