Purification fume hood
Description
I. Product Features
1. **Metal Components:** Primarily constructed from ≥1.2mm galvanized steel sheet, featuring an electrostatic epoxy powder coating. This coating includes a durable, chemical-resistant, and lead-free finish, ensuring a high-gloss surface while minimizing the effects of corrosion and moisture.
2. **Front and Side Panels:** Primarily constructed from ≥6mm acrylic sheet. This material offers excellent weather resistance and superior chemical resistance; it is highly resistant to aging, colorless, transparent, and fully translucent, providing visual comfort and an aesthetically pleasing, elegant appearance.
3. **Control System:** Features a 7-inch LCD touchscreen display and PLC control system. It provides real-time monitoring of ambient temperature and humidity, fan status, and VOC concentration levels, and incorporates an integrated alarm system.
4. **Fan:** Equipped with a PSC fan operating on a 24V DC current. It delivers stable performance, operates with ultra-low noise, and is spark-free (anti-static).
5. **Filtration System:** Filters are arranged and distributed based on particle size, adhering to ASTM standards. The system effectively targets acidic and organic gases with strong adsorption capabilities. For particulate matter, it utilizes high-efficiency HEPA filters, achieving a filtration efficiency of 99.995% for particles larger than 0.3µm.
6. **LED Lighting:** Provides illumination equivalent to a 25W fluorescent lamp. It generates no heat, ensuring safety and preventing any impact on the ambient temperature within the experimental environment. It is energy-efficient, eco-friendly, and features a long service life.
7. **Epoxy Resin Worktop:** Offers superior chemical stability and exceptional corrosion resistance. It features excellent impact resistance (remaining undamaged under impact) and high-temperature resistance. The material is solid-core throughout—preventing delamination, swelling, or cracking—and ensures a long service life.

**Working Principles**
1. **Side Air Intake Ports:** Air is drawn directly into the fume hood from beneath the side panels. This creates a negative pressure environment where a stable face velocity forms a natural barrier, effectively isolating the user from the chemicals being handled.
2. **Comprehensive Filtration System:** The fan system draws toxic and harmful gases upward through the filtration unit, returning clean, purified air back into the room. The cabinet’s superior containment control ensures that chemical gases generated within the enclosure do not escape back into the laboratory environment to cause contamination.
3. **Laboratory Air Purification:** Filters are configured specifically to suit different experimental operations, allowing for the effective filtration of various toxic and harmful gases. This process purifies the laboratory air, eliminates residual chemical odors, and enhances the overall air cleanliness level of the laboratory environment. 4. Purifies Surrounding Air
The fume hood’s continuous filtration efficiency helps to purify the indoor environment.
