The fume hood is a commonly used laboratory equipment designed to safely remove harmful gases and manage waste during experiments. It ensures a clean and safe working environment by incorporating efficient ventilation, drainage, and power systems.
**Product Features**
This fume hood is equipped with a multi-functional power socket that allows the easy connection of various electrical devices in the lab. A quick-opening valve provides convenient access to water during experiments. The front baffle is a movable glass door, while the top houses a low-speed exhaust fan that effectively removes hazardous and odorous gases. The work surface includes a stainless steel sink connected to a drain tank, enabling the safe disposal of disinfectants and experimental residues, thus maintaining a hygienic and secure lab environment.

**Structure**
The frame is constructed using dust-free, fireproof high-density board, while the working area is made of stainless steel veneer with an electrosprayed surface. This design ensures a smooth, dust-free, and durable surface that enhances both aesthetics and functionality.
**Working Principle**
The fume hood uses a low-noise centrifugal fan at the top to draw air into a static pressure tank and evenly distribute it through a PVC pipe, creating a negative pressure air curtain. This system quickly removes contaminated air from the workspace, ensuring a safe and controlled environment within minutes of startup. A touch-sensitive switch allows for easy adjustment of airflow, maintaining optimal wind speed throughout the experiment.
**Installation and Use**
Place the fume hood in a clean, well-ventilated area. After connecting to a 220V AC power supply, turn on the unit according to the control panel instructions. Before operation, ensure the working area and casing are thoroughly cleaned. Allow five minutes for the system to stabilize before starting the experiment.
**Maintenance**
1. If the ideal wind speed cannot be achieved even when the fan voltage is at maximum, it may indicate dust buildup in the ducts, requiring cleaning or replacement.
2. When replacing ducts or fittings, always use original manufacturer-approved sizes and ensure proper sealing to prevent leaks.
**Common Faults, Causes, and Solutions**
| Fault Phenomenon | Cause | Solution |
|------------------|-------|----------|
| Main power switch does not close, automatic tripping | Fan stuck, motor blocked, or circuit shorted | Adjust fan position, replace impeller or bearing, check wiring |
| Fan does not turn | Contactor failure or blown fuse | Check contactor circuit, replace fuse |
| Fluorescent light not lit | Damaged lamp or relay, blown fuse | Replace lamp or relay, replace fuse |
