Semi-Automatic Chemistry Fume Hood: Professional Laboratory Safety Solution
Luoyang Youken Laboratory Equipment Co., Ltd. offers cutting-edge Semi-Automatic Chemistry Fume Hood solutions engineered in our 30,000 m² production facility by 100 professional engineers. Our semi-automatic fume hood integrates advanced multi-duct laminar flow air supply technology with precision-controlled exhaust air flow ranging from 220-360 m³/h at standard height.
Constructed from robust 1.0 mm cold-rolled steel sheet, this system maintains a 60% make-up air ratio for optimal energy efficiency. The qualified air leakage rate ensures your laboratory meets international safety standards while reducing operational costs. Each unit features two double-door storage cabinets as standard, with optional frame-type structural upgrades available to match your specific workflow requirements.

Advanced Airflow Technology for Superior Protection
Your laboratory deserves containment systems that respond intelligently to changing conditions. Our semi-automatic fume hood adopts multi-duct laminar flow air supply that creates consistent negative pressure zones.
The system maintains precise face velocity without constant manual adjustment. This smart approach protects yOur Team from hazardous inhalants and chemical vapors while preventing energy waste from sashes left open inadvertently.
Upper and lower cabinets connect seamlessly to your exhaust system. This integrated design ensures comprehensive ventilation coverage throughout the entire working zone.
Premium Materials and Construction Quality
We construct our hoods using 1.0 mm cold-rolled steel sheet treated with moisture-proofing technology. This specialized treatment prevents moisture intrusion that could compromise structural integrity over time.
Waterproof coating blocks ambient moisture from the air. Your equipment stays protected even in high-humidity laboratory environments.
The chemical-resistant construction withstands corrosive environments without structural failure. This durability translates to lower replacement costs and extended service life for your facility.
