Laboratory ventilation is a critical aspect of ensuring a safe and efficient working environment. As the heart of scientific research, laboratories play a pivotal role in advancing technology and innovation. Renowned laboratories around the world are often seen as hubs for groundbreaking discoveries and academic collaboration, where researchers from all over the globe gather to exchange ideas and push the boundaries of knowledge.
In terms of ventilation requirements, laboratories must maintain proper air quality to protect both personnel and sensitive equipment. Unlike regular office spaces, laboratory environments require specialized ventilation systems that not only provide comfort but also ensure safety by removing hazardous substances. This includes maintaining a continuous supply of fresh air from outside, while exhausting contaminated air directly outdoors—never allowing it to recirculate within the building.
For example, chemical laboratories typically require more than 10 air exchanges per hour, while physical laboratories may need fewer, around 6 to 8 exchanges. The fume hoods, which are essential in many labs, should be designed to operate independently from general room ventilation. Additional local exhaust systems may also be required for areas where hazardous materials are used or generated.
The ventilation system must also be integrated with the overall HVAC (Heating, Ventilation, and Air Conditioning) system. Fresh air is supplied into the lab based on the exhaust volume, while some of the air is directed to non-laboratory areas to maintain proper pressure differentials. This helps create a controlled airflow pattern, moving from less critical areas like offices and corridors into the experimental zones. Fume hoods are strategically placed away from high-traffic and high-airflow areas to minimize contamination risks.

The SW-TFG series fume hood is a commonly used piece of equipment in laboratories, especially in settings where harmful gases are generated during experiments. It ensures that these gases are effectively removed and that the workspace remains safe for users.
**Working Principle**
This fume hood is equipped with a water, electricity, and gas system, along with multiple power sockets to accommodate various experimental devices. A quick-opening valve allows easy access to water during experiments, while the front baffle, made of a movable glass door, provides a clear view and protection. The top of the hood houses a low-speed exhaust fan that smoothly removes harmful and odorous gases. A stainless steel sink at the base of the work area helps in washing away residues and disinfectants, ensuring a clean and safe environment.
**Structural Features**
The frame is constructed from fireproof MDF material, while the working area is covered with stainless steel veneer. This design offers excellent sealing, durability, and an attractive appearance.
