Ductless Fume Hood LFH-A21 Manual
Labtron Ductless Fume Hood is specialized to provide safe ventilation and protection from harmful fumes and particulates without need for external ductwork. They are equipped with HEPA or activated carbon filters that capture hazardous substances before air released back into room. Their adjustable transparent sash provides optimal access while maintaining without compromising safety. They include built-in exhaust fan to improve air circulation and overall hood performance. Our Ductless Fume Hood is ideal for cosmetic formulation, material analysis, electronic manufacturing and pharmaceutical development.
Labtron’s Ductless Fume Hood LFH-A21 differs significantly from traditional ducted systems as it eliminates the need for external ductwork. Instead, it uses a built-in centrifugal blower and two chemical filters to remove harmful fumes and particulates from the air. This makes it easier to install, highly portable, and ideal for modular or temporary lab spaces where permanent ducting is not feasible.
The Ductless Fume Hood LFH-A21 is designed with multiple safety layers: a microprocessor-controlled electronic system prevents electrical overloads and shocks, while internal and external air quality probes continuously monitor filter conditions and environmental safety. Additionally, it features a UV sterilization lamp for decontaminating the work area and audible/visual alarms to indicate when filters need to be changed.
