Esco Ascent Max 4ft Ductless Fume Hood B Series Model ADC-4B2
Reliable Standard Ductless Fume Hood for General Laboratory Applications
The Esco Ascent Max 4ft Ductless Fume Hood B Series (ADC-4B2) is designed for general lab applications such as dilution, mixing, and buffer preparation. Featuring a main carbon filter, this ductless fume hood effectively removes chemical fumes while safely recirculating clean air back into the laboratory.
With low noise operation, energy-efficient airflow, and plug-and-play installation, the ADC-4B2 is a practical, cost-effective solution for laboratories seeking safe chemical containment without requiring complex ductwork.
Key Benefits
- Main Carbon Filtration: Safely captures chemical fumes for routine lab processes.
- Certified Containment: Negative pressure airflow and auto-purge slots prevent fumes from escaping the work zone.
- Energy-Efficient & Quiet: Direct-drive centrifugal fan reduces noise and operating costs.
- Advanced Airflow Monitoring: Sentinel Silver microprocessor continuously monitors airflow and triggers alarms for unsafe conditions.
- Durable & Hygienic: Industrial-grade electro-galvanized steel with ISOCIDE antimicrobial coating minimizes contamination.
- Flexible Filtration Options: Optional secondary backup carbon or HEPA filter available.
