Intervention at Source

Local exhaust systems are specialized ventilation units that capture and remove harmful gases, vapors, or dust at the source, ensuring their extraction from the environment. They are used in soldering, welding, chemical processes, and many other industrial applications.

Operating Principle:

Local exhaust systems operate with a suction head (hood) located close to the point where harmful substances are generated, connected to a duct system. The suction head captures the harmful substances and directs them to a filtration unit or exhausts them to the outside through the duct system.

Advantages:

• Targeted Intervention: Prevents contamination of the overall laboratory environment by capturing harmful substances at their source.
• Energy Efficiency: Provides ventilation only where needed, leading to energy savings.
• Flexibility: Can be customized for different applications.
• Easy Installation: Typically, easy to assemble and portable.

Selection Criteria:

• Application: The types of harmful substances and processes involved.
• Type of Suction Head: Proper selection of the hood based on the type and spread of the harmful substance is important.
• Airflow Rate: Should be adjusted based on the quantity and spread rate of the harmful substance.
• Filtration System: Proper selection of filters depending on the type of harmful substance is necessary.

Local exhaust systems are an effective solution for protecting worker health and preventing environmental pollution. With the right choice and regular maintenance, they can be used efficiently for many years.

The Protector of Your Laboratory Bench

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.

The Safe Haven of Your Laboratory

Draft Chambers are specialized enclosures designed to safely evacuate harmful gases and vapors that arise during processes such as chemical reactions, solvent evaporation, or the use of dusty materials in laboratories. They are of critical importance in safeguarding the health of workers and controlling the release of potentially harmful substances into the environment.

Operating Principle:

Draft Chambers operate on the principle of negative pressure. The air pressure inside the chamber is kept lower than the pressure outside. This ensures that harmful gases and vapors generated inside the chamber are captured by the internal airflow and are either purified through filters or directly vented outside, preventing their escape into the surrounding environment.

Advantages:

• Worker Safety: Minimizes the risk of exposure to harmful gases and vapors.
• Environmental Protection: Prevents the spread of harmful substances into the environment.
• Fire Safety: Ensures the safe handling of flammable and explosive materials.
• Flexibility: Available in different sizes and configurations, they can be customized to fit the needs of your laboratory.

Selection Criteria:

• Intended Use: The types of chemicals or processes for which it will be used.
• Size: The available space in the laboratory and the required working volume.
• Airflow Rate: Varies depending on the type and quantity of chemicals used.
• Filtration System: Selecting the appropriate filter is crucial depending on the type of harmful gases and vapors.

Draft Chambers are an essential investment in ensuring 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.

The Basis of Laboratory Safety

Laboratory environments are specialised areas where scientific research and experiments are conducted and sensitive and potentially risky substances are used. Therefore, effective ventilation systems are vital to protect the health of laboratory workers and ensure a safe working environment.

Ventilation systems provide fresh air circulation by removing harmful gases, vapours, dust and other particles from the environment in laboratories. This protects the health of employees and increases the reliability and accuracy of experiments.
