Ductless Fume Cupboard FAQ
About Deiiang™ Laboratory Ductless Exhaust System Solution
Engineered with over a decade of filtration expertise, Deiiang™ delivers a high-performance ductless exhaust solution that autonomously purifies hazardous laboratory air without complex ventilation infrastructure. Our systems utilize compliant, industrial-grade filtration technology to meet strict NFX 15-211 safety standards, ensuring precise containment of toxic vapors for personnel protection.
Trusted by research facilities worldwide, we provide a sustainable, energy-efficient alternative that reduces HVAC strain while maintaining a rigorously safe working environment.
Why Choose Deiiang?
At Deiiang, manufacturing is not just assembly; it is a discipline refined over decades of hands-on engineering. We don’t just bend steel; we understand the daily rhythms of a busy lab.
Our “Silent-Weld” construction technique was developed after years of listening to feedback from lab managers who needed quieter, vibration-free environments for sensitive microscopy work. Every joint is hand-inspected by technicians with an average of 15 years in containment engineering, ensuring the unit is not only chemically resistant but structurally sound enough to last a generation. When you choose Deiiang, you aren’t buying a generic box; you are investing in a safety solution built by experts who have stood exactly where you stand.

How does a Deiiang™ Ductless Fume Cupboard differ from a traditional ducted fume hood?
Unlike traditional hoods that expel air outside through expensive ductwork, Deiiang™ Ductless Fume Cupboards use advanced activated carbon and HEPA filtration to clean the air and recirculate it back into the laboratory. This makes them portable, energy-efficient, and easy to install, as they require no external venting.

Are Deiiang™ ductless hoods safe for all types of chemicals?
They are highly effective for a wide range of common laboratory chemicals, including solvents, acids, and bases. However, they are not suitable for radioactive materials or highly toxic gases that carbon cannot adsorb. Our technical team offers a complimentary Chemical Assessment Service to verify if your specific application is safe for our filtration technology.
Can I install a Deiiang™ fume cupboard myself?
Yes. One of the biggest advantages of our ductless design is the “Plug-and-Play” capability. The units arrive 90% assembled. You simply need to place the unit on a stable surface, install the filters using our Quick-Lock mechanism, and plug it into a standard electrical outlet.

How does the “Deiiang-Sorb™” filtration technology work?
Deiiang-Sorb™ is our proprietary multi-layered filtration system. It combines high-grade coconut shell activated carbon with bonded chemical impregnates to target specific molecular structures. This ensures that even volatile organic compounds (VOCs) are trapped effectively, preventing desorption and leakage.

Do your fume cupboards meet international safety standards?
Absolutely. Deiiang™ manufactures strictly according to JG/T 385-2012, NFX 15-211 (Class I and II), and ASHRAE 110 standards. We conduct rigorous containment testing in our in-house QA lab before shipping to ensure every unit meets the highest global safety benchmarks.
Can Deiiang™ customize the size or features of a cupboard for my lab?
Yes. As a direct manufacturer with deep engineering experience, we offer customization. Whether you need a specific width for a tight space, a polypropylene structure for high acid resistance, or a walk-in design for large equipment, our engineering team can build it.

What is the energy consumption compared to a ducted system?
Deiiang™ ductless cupboards are significantly more energy-efficient. Because they recirculate conditioned air rather than venting expensive heated or cooled air outside, our clients often see HVAC energy savings of up to 96% compared to traditional ducted systems.

Does Deiiang offer after-sales support and filter replacement services?
We pride ourselves on lifecycle support. We maintain a full stock of replacement filters ready for immediate shipment. Additionally, our support team provides annual maintenance checklists and remote troubleshooting to ensure your unit operates at peak safety for years.
Why is the noise level of Deiiang™ hoods lower than others?
We use high-efficiency, low-turbulence EC fans and our unique “Silent-Weld” construction to minimize vibration. This results in an operating noise level typically below 55 dBA, creating a quieter, less stressful working environment for lab technicians.
