Ductless PP Fume Hood

Cabinet: Constructed with 8mm milky white laminated high-quality PP (polypropylene) board, offering superior corrosion resistance. Seamlessly welded with color-matched welding rods to ensure structural integrity and airtightness.

Front & Side Panels: Made of ≥6mm acrylic panels with excellent weather resistance and chemical resistance. Colorless, transparent, and durable, providing clear visibility and aesthetic appeal.

*3. 7-inch LCD Touchscreen: High-definition display (1024×600 resolution) for intuitive operation and real-time monitoring.

*4. Real-time Environmental Monitoring: Tracks temperature and humidity, allows alarm parameter setting to ensure safe operation.

*5. Fan Monitoring: Alerts for fan system failure; adjustable fan speed online to meet varying chemical operation requirements.

*6. Filter Saturation Alarm: Triggers alerts when filter saturation exceeds 预设 thresholds, corresponding to VOC concentration levels. Filter replacement is required when both the alarm and concentration reach high levels.

Imported U.S. PSC Fan: 24V DC operation, stable performance, ultra-quiet, and spark-free for electrostatic safety.

High-efficiency Filtration System: Strategically layered filters following ASTM standards, targeting acidic and organic gases. HEPA filter captures ≥0.3μm particles with 99.995% efficiency.

LED Lighting: Equivalent to 25W fluorescent lamps, heat-free, energy-efficient, and long-lasting without affecting lab temperature.

Epoxy Resin Countertop: Exceptional chemical stability, corrosion/impact resistance, and high-temperature tolerance (≤180℃). Monolithic core design prevents delamination, swelling, and cracking.

Advantages

No Ductwork Required: Easy installation, zero exhaust emissions, and eco-friendly operation.

Modular Filter System: Customizable top-mounted filter modules for diverse experimental needs.

Advanced Filtration Technology: Fully adsorbs harmful gases, particulates, and odors generated during experiments.

Energy-saving: Eliminates air conditioning energy consumption, reducing operating costs.

Flexible Placement: Desktop or mobile cart configurations adapt to any lab environment.

Working Principle

Air Intake: Air is drawn directly from the lab into the fume hood, creating negative pressure. A stable face velocity (0.4–0.6m/s) forms a protective barrier between users and chemicals.

Comprehensive Filtration: Toxic gases are extracted upward by the fan, filtered through multiple stages, and recirculated as clean air. The cabinet’s precise concentration control prevents chemical backflow into the lab.

Laboratory Air Purification: Customizable filters (acidic/organic gas/HEPA) remove harmful substances, improve air quality, and enhance lab cleanliness.

Surrounding Air Cleaning: Continuous filtration helps purify ambient lab air, reducing chemical residue and odors.

Parameter (Specification)

Feature And Application

No need for external exhaust ducts. Exhaust gases are purified through a high - efficiency filtration system in a circulating manner, reducing environmental pollution.

Equipped with a 24V silent fan and LED lighting, the overall power of the unit is only 42W, saving over 30% energy compared to traditional fume hoods.

The modular filtration design enables quick replacement of organic/inorganic/HEPA filter elements, adapting to diverse experimental requirements.

Application Scenarios

Suitable for scenarios such as chemistry laboratories in universities and research and development centers of scientific research institutions. It can safely handle exhaust gases like volatile acids and organic solvents.

In environmental monitoring stations, it can effectively reduce the emission of low - concentration VOCs, meeting the standards of a green laboratory.
