Product Overview
Labotemp Ducted Fume Hood LFH-103 is a laboratory chemical fume hood designed to capture and exhaust hazardous fumes, vapors, gases and aerosols through an external ducted exhaust system. The unit features a corrosion-resistant solid work surface, a manual tempered-glass sash with bypass airflow, adjustable face velocity and an integrated variable-speed centrifugal blower to ensure controlled ventilation for research, QC and production environments.

Key Benefits

• Effective fume extraction with adjustable face velocity (0.3–0.8 m/s) and negative-pressure ventilation
• Enhanced safety with integrated UV sterilization, 5 mm tempered glass sash and antimicrobial cabinet coating
• Intuitive control via microprocessor controller with LCD display, memory function and airflow protection during power interruptions

Features

• Microprocessor controller with LCD display for operation and status monitoring
• Memory function for preset settings
• Adjustable airflow velocity 0.3–0.8 m/s
• 20 W UV lamp and 8 W LED workspace illumination and sterilization
• Chemical-resistant solid physicochemical work surface (phenolic resin / compact laminate)
• Antimicrobial powder-coated steel cabinet
• Front bypass airflow system with 5 mm tempered glass adjustable sash (manual)
• Waterproof sockets, gas and water taps
• Built-in variable-speed centrifugal blower
