Microzone HLF-2-4 Horizontal Laminar Flow Clean Bench Hood

Microzone HLF-2-4 Horizontal Laminar Flow Clean Bench Hood

This equipment is used to create a sterile, particle-free work area to protect sensitive samples from contamination. It is commonly called a clean bench or laminar flow hood. It works by drawing room air through a pre-filter, passing it through a high-efficiency HEPA filter, and blowing a continuous stream of clean, purified air horizontally across the workspace directly toward the user.

Specs:

• Electrical Requirements:115V AC, 60 Hz (plugs into standard North American commercial wall outlets)
• Illumination: Energy-efficient, high-output LED task lighting mounted inside the upper enclosure ceiling
• Auxiliary Outlets: Typically features dual internal duplex electrical outlets on the work zone ceiling for powering equipment like vortexers or stirrers
• Germicidal Control: Equipped with a built-in UV-C disinfection lamp for surface sterilization routines before laboratory procedures
• Nominal Width: 4 feet
• Work Zone Width: Approximately 48 inches
• Exterior Shell: Robust, commercial-grade cold-rolled steel construction finished with a durable, anti-microbial powder coat paint
• Work Surface: High-grade, flat-profile stainless steel designed for easy wipe-downs, sanitization, and chemical resistance
• Side Windows: Laminated safety glass inserts for side-viewing clarity and optimal ambient light penetration
• Airflow Direction: Horizontal (Rear-to-Front) positive pressure laminar stream
• Main HEPA Filter: Rated at 99.99% efficiency at capturing micro-particulates down to 0.3 microns
• Pre-Filtration: Uses disposable, user-replaceable pleated pre-filters (typically twin 16" x 20" MERV 8 filters) positioned to catch large dirt particles and extend primary HEPA life
• Cleanliness Rating: Delivers a minimum of an ISO Class 5 (Class 100) sterile environment directly inside the active work zone
• Average Face Velocity: Set to maintain a uniform airflow output speed of approximately 0.40 m/s (approx. 80–90 fpm) across the filter face
