Fume Hoods | Low airflow

LDN

Safe, comfortable, energy-saving fume hood.

With a unique exhaust design, the exhaust air volume is reduced by about 40%, while maintaining the same containment performance as previous products.

• Through a unique high-efficiency exhaust design, excellent containment performance is achieved even with low exhaust air volume, reducing exhaust air volume by approximately 40%.
• Due to the low air volume, it effectively reduces the costs of air conditioning equipment, operational costs, and environmental load, achieving energy savings with LED lighting.
• High containment performance is realized through our company's exclusive new slit-type buffer plate, a two-layer flow slit method that drives air, and the containment function has passed the EN test verification (European Standard/EN14175-3: 2003).
• The front glass door is larger than previous products, providing a better internal view. Additionally, it features a dual-safety drop prevention structure for the door and a glass door opening limit positioning (with key) as standard configuration.
• An optional LED digital display air volume monitor is available for easy daily management, which alerts laboratory personnel with a buzzer and indicator light when air volume is abnormally low.
