Chemical fume hood LFH-103

containmentexhaustfor the food industry

Overview
LFH-103 ducted fume hood provides operator and environmental protection by capturing and exhausting hazardous fumes, vapors, gases and aerosols via a negative-pressure ventilation system. Designed for routine chemical handling, research and quality-control tasks, it features a chemical-resistant work surface and adjustable face velocity for controlled extraction.

Why Choose LFH-103

• Effective extraction: Adjustable face velocity 0.3–0.8 m/s with negative-pressure airflow for reliable removal of hazardous emissions.
• Laboratory safety: UV sterilization, tempered glass sash, front bypass airflow and chemical-resistant work surface reduce contamination and exposure risks.
• Operational control: Microprocessor controller with LCD, airflow adjustment and memory protection for consistent performance and monitoring.

Features

• Microprocessor controller with LCD display for real-time status and adjustments.
• Adjustable airflow velocity 0.3–0.8 m/s.
• 20 W UV lamp and bright LED illumination.
• Chemical-resistant phenolic work surface and antimicrobial powder-coated steel cabinet.
• Front bypass airflow system with 5 mm tempered glass adjustable sash.
• Waterproof sockets, gas and water taps integrated into the work area.
• Variable-speed built-in centrifugal blower for stable exhaust performance.
• Memory function for saved settings and power-interruption protection.
