Chemical fume hood LFH-01

exhaustlaboratoryfor the pharmaceutical industry

Product Overview
Labotemp Ducted Fume Hood LFH-01 is a duct-connected laboratory fume hood designed to capture and exhaust hazardous fumes for chemical, pharmaceutical and research environments. Engineered for continuous indoor use with an external ducting system, the unit maintains a recommended face velocity ≥0.50 m/s to reduce operator exposure during reactions, sample preparation and analytical procedures.

Construction & Usability
The LFH-01 features a cold-rolled, powder-coated steel body with corrosion-resistant finishes and an acid/alkali-resistant work surface suited to aggressive reagents. A tempered glass sash provides clear visibility and smooth vertical operation. Integrated LED lighting and a touch control panel allow precise adjustment of airflow and functions. Electrical protection includes overload protection and grounding to meet laboratory safety requirements.

Features

• Corrosion-resistant, powder-coated cold-rolled steel construction
• C hemical-resistant work surface compatible with solvents and strong reagents
• Tempered (toughened) glass sash for safe visibility and smooth movement
• User-friendly touch control panel for airflow and function adjustment
• Integrated LED illumination for consistent workspace lighting
• Low vibration and noise design suitable for extended use
• Electrical safety: overload protection, grounding; withstand voltage 1500 V; ground resistance ≤ 0.1 Ω
• Lab-grade power socket for auxiliary equipment
• Modular interior for simplified cleaning and maintenance
• Optimized exhaust structure for improved ventilation efficiency when connected to external ducting

Applications

• Safe handling and extraction of volatile, toxic or flammable gases in ducted laboratory exhaust systems
• C hemical synthesis, sample preparation and analytical testing in pharmaceutical, academic and industrial labs
• Situations requiring controlled inlet face velocity (≥0.50 m/s), low noise and electrical safety compliance

Optional Accessories

• Fan accessories (air valve)
• Exhaust fan
• Air duct (2 pcs per set)
• Bend (2 pcs per set)
