Laminar flow equipment combines high-efficiency HEPA/ULPA filtration with furniture (hoods, benches, consoles, etc.) to remove particles and contaminants from workstations. The laminar flow continuously sweeps particles away from sensitive work areas, ensuring ISO compliance within your controlled environment. All our products are Made in the USA.
Configuration Options: Vertical vs. Horizontal Laminar Flow
The first decision in selecting equipment is determining the direction of airflow. Both configurations provide Class 100 (ISO 5) or better air quality, but they serve different operational needs.
Vertical Laminar Flow (VLF): HEPA filters are located above the work surface, blowing air downward.
Best For: Applications involving large equipment or tall items that would block horizontal air. VLF mimics the airflow of a full-scale cleanroom and is less likely to blow contaminants or fumes directly at the operator’s face.
Key Advantage: Gravity works with the airflow to move particles toward the floor or exhaust vents.
Horizontal Laminar Flow (HLF): HEPA filters are located at the back of the unit, blowing air forward across the work surface toward the operator.
Best For: Working with small, delicate items placed directly on the bench. Because there is no "hand-over-product" interference from above, HLF offers the "cleanest" air at the most critical point of contact.
Key Advantage: Minimal turbulence on the work surface and easier access for overhead clearance.
Equipment Types: Hoods, Benches, Consoles, and Stations
Liberty Industries offers a variety of equipment fit with laminar flow filtration systems (and stand-alone filtration systems) to accommodate different facility layouts and process requirements:
Laminar Flow Hoods & Tabletop Units
Hoods can be compact, portable units designed to be placed on existing lab benches or work tables. They are the ideal solution for facilities with limited space or those needing to create a "clean zone" within a larger, unclassified room.
Laminar Flow Benches
Benches are fully integrated workstations where the airflow system and the work surface are a single unit. These are often built with heavy-duty frames and are available in stainless steel or laminated Novaply to meet specific chemical resistance requirements.
Floor-Standing Console Stations
Consoles are self-contained, floor-standing units. They offer a larger work envelope than tabletop hoods and often feature optional vibration-isolated work surfaces, making them perfect for microscopy or high-precision weighing.
