Cole-Parmer FHD-400 Advanced Ductless Fume Hood, 39" Width; 230 VAC, 50 Hz

Description

Operating on 230 VAC, 50 Hz power, this 39-inch wide ductless fume hood is suited for regions or facilities with this electrical standard. It provides a self-contained workstation for filtering chemical vapors and particulates without the need for external exhaust ducts. The system typically employs a filtration sequence that includes a pre-filter for particles and specialized main filters, such as bonded carbon, to adsorb various organic vapors, acids, and formaldehyde. Design features often encompass a constant airflow monitoring system to verify safe face velocity, a transparent sash for a protective barrier and visibility, and interior lighting. The work area is usually made from chemical-resistant materials for easier cleaning. This model offers placement flexibility and can reduce energy costs associated with exhausting conditioned air, making it applicable for educational, quality control, or supplemental research environments. Consistent filter maintenance and monitoring are essential for safe operation.
