Ventilation Systems

Fume hoods are ventilation systems placed on laboratory benches, designed to capture and exhaust harmful gases, vapors, and particles. They are commonly used in chemistry, biology, pharmacy, and many other types of laboratories.

Operating Principle:

Fume hoods operate on the principle of negative pressure. The air inside the hood is kept at a lower pressure than the surrounding air. This allows harmful substances to be drawn into the hood and safely exhausted without spreading into the laboratory environment.

Advantages:

• Worker Safety: Reduces the risk of exposure to harmful substances.
• Fire Safety: Enables the safe handling of flammable and explosive materials.
• Flexibility: Available in various sizes and configurations.
• Easy to Use: User-friendly design for easy operation and maintenance.

Selection Criteria:

• Intended Use: The types of chemicals or processes for which it will be used.
• Size: The size of the bench and the required working area.
• Airflow Rate: Varies depending on the type and quantity of chemicals used.
• Filtration System: Choosing the appropriate filter is crucial depending on the type of harmful gases and vapors.

Fume hoods are an important investment in the safety of your laboratory and the health of your workers. With the right choice and regular maintenance, they can be safely used for many years.
