Ductless Filtration Fume Hoods Series
Ductless Filtration Series: Professional Fume Hoods, PCR Cabinets & Weighing Stations
The Ductless Filtration Series represents a modern, eco-friendly solution for laboratory safety. Designed for high-efficiency air purification, these units—including Standard Ductless Fume Hoods, Weighing Stations, and PCR Workstations—recirculate purified air directly back into the laboratory. This eliminates the need for expensive external ductwork while maintaining a constant temperature environment.
Key Technical Characteristics
• Rapid Installation: Featuring a modular design, these units are easy to install, with standard setups typically completed within one hour.
• Maximum Mobility: Equipped with movable bases, the equipment can be repositioned anywhere in the laboratory as needed without pipe requirements.
• Ergonomic Design: The forward-facing work panel and transparent acrylic side panels provide high translucency and an intuitive operating experience.
• Energy Efficiency: By purifying and storing air indoors, the system avoids the energy loss associated with exhausting conditioned air outside.
• Advanced Monitoring: Standard configurations include temperature monitoring, filter saturation monitoring, and fan monitoring.

FAQs
1. What makes the filtration in this series safer than standard models?
The equipment utilizes a double-layer molecular filter system, which provides higher adsorption efficiency, increased safety, and a longer service life.
2. How does the system monitor both internal and external air quality?
The series features a built-in TVOC and temperature monitoring system, as well as an external probe designed to monitor the pollution status of the surrounding indoor air.
3. What specific fan technology is used in these units?
Both the fume hoods and storage cabinets are equipped with American PSC brushless motors, offering ultra-quiet operation, adjustable air volume, and a long lifespan of up to 60,000 hours.
4. Can I choose different filters for specific chemical hazards?
Yes, there are multiple specialized filter models available, including the HF4TY for acid and organic gases, HF4AM for ammonia, HF4FM for formaldehyde, and HF4HP for particle filtration with 99.995% efficiency.
5. Are the storage cabinet shelves customizable?
Yes, the shelves are made of corrosion-resistant PP material and can be adjusted according to the size of your containers. Each shelf can bear a load of up to 200kg.
6. How sensitive is the wind speed monitoring?
The system uses high-sensitivity electronic surface wind speed sensors imported from Japan to ensure precise airflow control.
7. Is the lighting safe for high-risk laboratory environments?
Yes, the units are equipped with high-brightness LED explosion-proof lighting, which serves as a cold light source for enhanced safety.
8. What prevents chemical splashes during operation in the fume hood?
The fume hoods feature an ergonomic trapezoidal opening specifically designed to prevent chemical splashes while providing comfortable access for the user.
9. How do I manage multiple power cords for internal instruments?
The equipment includes a concealed power cord card slot for easy access and organization of various power cords, along with reserved threading holes on both sides of the machine.
10. What are the options for the work surface?
Users can select from epoxy resin boards (standard or balance-weighing grade), easy-to-clean ceramic countertops, or corrosion-resistant tempered glass with a concave liquid-filling design to prevent overflows.
11. Can the equipment be leveled on uneven laboratory floors?
Yes, the filtration storage cabinets feature individual adjustable support feet, and the movable units use high-intensity Fuma wheels with adjustable height and fixing capabilities.
12. Is the operation of the acrylic doors easy to manage?
The design includes removable hooks specifically for easy and smooth acrylic door operation.
13. Does the system provide real-time status updates?
Yes, a large LCD display is integrated into the units to provide clear and easy-to-operate monitoring of the system's performance and filter status.
14. What optional accessories are available for acid storage?
For concentrated acid handling, specialized accessories like the Hydrochloric acid box are available for extra protection within the filtration cabinet.
15. Can the fume hood be used for precision weighing?
Yes, when equipped with the 19/25mm epoxy resin board, the unit provides the flat sensitivity and stability required for dust weighing and balance experiments.
