Introduction to the components of fume hoods

Fume hoods are common key equipment in laboratories, used to control, dilute and remove harmful gases, smoke and particles produced during experiments. The components of a fume hood are diverse, and each component plays an important role. The following is a detailed introduction to the main components of the fume hood:

1. Frame and cabinet base materials

Material: Usually, cold-rolled steel plates, epoxy resin base paint, etc. are used for anti-corrosion treatment.

Function: Support the entire structure of the fume hood to ensure its stability and durability.

2. Work surface

Material: Solid physical and chemical board, stainless steel plate, PP material, etc.

Features: High-temperature resistant, acid and alkali resistant, easy to clean.

Function: To provide an operation platform for laboratory personnel to place experimental equipment and samples.

3. Pool

Material: Polymer composite material.

Features: High-temperature resistant, acid and alkali resistant, corrosion resistant, and easy to clean.

Function: To facilitate the cleaning and preparation work of laboratory personnel.

4. Window

Material: Tempered glass.

Thickness: Usually 5mm or 6mm.

Features: High transparency, explosion-proof, and impact-resistant.

Function: It provides a clear field of vision, facilitating the observation of the experimental process by laboratory personnel, and at the same time isolates harmful gases.

5. Sliding Door (Activity Door)

Material: Safety glass or tempered glass.

Features: It can slide or move up and down, facilitating the adjustment of the opening size of the fume hood.

Function: To control the gas exchange between the inside and outside of the fume hood and prevent the escape of harmful gases.

6. Wind supplement wing

Location: Arranged along the workbench surface.

Function: Guide the airflow to pass smoothly through the sliding door plane of the fume hood, prevent turbulence from occurring, and improve the capture efficiency.

7. Deflector plate

Material: Anti-Bette board, etc.

Function: To ensure that the airflow passes evenly through the sliding door surface of the fume hood, eliminate dead corners, and optimize the capture efficiency.

8. Exhaust port

Location: The top or side of the fume hood.

Function: To expel the harmful gases inside the fume hood to the outside.

9. Control System

Composition: It includes power control, fan control, lighting control, air volume regulation, etc.

Features: Intelligent control, facilitating laboratory personnel to adjust the working state of the fume hood as needed.

Function: Ensure the normal operation of the fume hood, improve the efficiency and safety of experiments.

10. Fan

Type: Generally, fans that are corrosion-resistant, explosion-proof, low-energy-consuming and low-noise are selected.

Function: Provide exhaust power to expel harmful gases from the fume hood to the outside.

11. Other accessories

Power socket: Provides power supply for the experimental equipment.

Lighting equipment: Provide sufficient lighting to facilitate the operation of laboratory personnel.

Faucets and gas faucets: They are convenient for laboratory personnel to clean and prepare.

Base feet: Adjust the height and stability of the fume hood.

Handles and hinges: Sliding doors that facilitate the opening and closing of fume hoods.
