Cole-Parmer FHD-400 Advanced Ductless Fume Hood, 49" Width; 230 VAC, 50 Hz
Manufacturer: Cole-Parmer
Description
This version of the FHD-400 ductless fume hood features a 49-inch wide workspace and is configured for 230 VAC, 50 Hz operation. It is engineered as a self-contained workstation for handling low-to-moderate hazard chemicals in situations where ducted ventilation is not feasible. The system employs a multi-stage filtration process to neutralize hazardous fumes, vapors, and particulates directly, recirculating purified air back into the room and avoiding the need for external ducting. The interior is accessed via a vertically rising sash and is typically constructed from durable, chemical-resistant materials. Integrated safety features commonly include airflow monitors and filter saturation indicators to alert users to maintenance needs. The unit's portability allows for relocation within a laboratory as needs change. By not exhausting conditioned indoor air, it can contribute to energy efficiency. It is suitable for applications in educational, quality control, and certain industrial process settings.
