Erlab Flow 714 Smart Vertical Laminar Flow Clean Bench

Overview

The Erlab Flow 714 Smart Vertical Laminar Flow Clean Bench is an engineered solution for maintaining ISO Class 5 (formerly Class 100) particulate-controlled environments in laboratory and light industrial settings. It operates on the principle of vertical unidirectional airflow: ambient air is drawn through a prefilter, conditioned, and then forced downward through a certified H14 ULPA filter (EN 1822-1 compliant, ≥99.995% efficiency at MPPS ≥0.3 µm). This creates a continuous, low-turbulence curtain of purified air across the work surface—effectively shielding samples from airborne contaminants such as dust, microorganisms, and aerosolized particles. Unlike biosafety cabinets, this unit does not protect personnel or the environment from hazardous agents; it is designed exclusively for product protection in non-hazardous applications including cell culture, sterile media preparation, semiconductor handling, pharmaceutical quality control, and food microbiology. Its structural integrity, airflow stability, and compliance with EN ISO 14644-1 and EU GMP Annex 1 (Class A/B environments) make it suitable for GLP- and GMP-aligned workflows where sample integrity is critical.

Key Features

• ULPA-grade H14 filtration system validated per EN 1822-1, delivering consistent ISO Class 5 performance across the full work surface
• Interlocked UV-C germicidal lamp with automatic shutoff upon sash movement—ensuring operator safety and preventing cross-contamination between procedures
• Ergonomic front sash design with optimized tilt angle and wide access aperture (1697 mm internal width), reducing operator fatigue during extended use
• High-efficiency LED lighting (>800 lux uniformity) positioned to minimize shadows and glare without generating thermal load
• Dual-surface configuration options: electropolished 304 stainless steel (2 mm thickness, radius-edged, non-porous) or 25 mm solid phenolic board (chemical-resistant, non-conductive, with integral spill containment groove)
• Intelligent fan control supporting two preset airflow modes (1040 m³/h high-flow / 690 m³/h low-noise), each at fixed 2100 RPM for stable velocity (0.35 m/s face velocity)
• Acoustic optimization yielding ≤61 dBA at operator position—critical for shared lab environments requiring low ambient noise

Sample Compatibility & Compliance

The Flow 714 Smart is validated for use with non-pathogenic biological materials, sterile reagents, sensitive electronic components, and precision weighing operations involving low-volatility chemicals. It meets ISO 14644-1:2015 Class 5 requirements for particle concentration (≤3,520 particles/m³ ≥0.3 µm), aligning with U.S. Federal Standard 209E Class 100 and EU GMP Annex 1 classifications for Grade A (aseptic processing) and Grade B (background environment) zones. While not certified for containment of biohazards or volatile organics, optional GF4BE+ activated carbon filtration modules may be installed to mitigate low-concentration acidic, alkaline, or organic vapors—supporting applications in analytical chemistry prep or material synthesis where gaseous interference must be minimized. All configurations comply with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and support audit readiness under FDA 21 CFR Part 11 when integrated with compliant data logging systems.

Software & Data Management

The Flow 714 Smart operates via embedded microcontroller logic—no external PC or proprietary software is required for basic operation. However, optional digital interface modules enable RS-485 or Modbus RTU connectivity for integration into centralized facility monitoring platforms (e.g., LabVantage, Siemens Desigo, or custom SCADA). Real-time parameters—including fan status, UV lamp cycle count, cumulative runtime, and filter service interval alerts—are accessible via front-panel LCD display with multilingual UI (English default). Filter life estimation (up to 4 years under typical ISO Class 8 ambient conditions) is calculated based on cumulative airflow hours and upstream particulate loading assumptions. Audit trails for UV activation/deactivation events are timestamped and stored locally for ≥12 months—supporting GLP documentation requirements when paired with external validation protocols.

Applications

• Aseptic handling of mammalian and insect cell lines in academic and contract research laboratories
• Preparation of sterile culture media, buffers, and reagents for QC microbiology testing
• Assembly and inspection of microelectronic components and photomasks in cleanroom-adjacent spaces
• Weighing of reference standards and active pharmaceutical ingredients (APIs) under controlled particulate conditions
• Non-hazardous chemical dispensing, dilution, and formulation where vapor-phase contamination must be avoided
• Support of ISO/IEC 17025-accredited testing procedures requiring documented environmental controls

FAQ

Does the Flow 714 Smart provide personnel or environmental protection?
No. It is a product-protection-only device. For operator or environmental protection against biohazards or toxic chemicals, a Class II biosafety cabinet or fume hood is required.
Can the H14 ULPA filter be replaced in-house?
Yes—filter replacement is tool-free and requires no recalibration. Erlab provides certified replacement kits with batch-traceable test reports per EN 1822.
Is third-party certification available for ISO Class 5 validation?
Yes. Erlab partners with ISO 17025-accredited service providers to perform on-site airflow visualization, particle counting, and velocity mapping per ISO 14644-3.
What maintenance intervals are recommended?
Pre-filter cleaning every 2 weeks; ULPA filter replacement every 2–4 years depending on ambient air quality; UV lamp replacement annually or after 8,000 hours of operation.
Can the unit be installed in a non-cleanroom space?
Yes—its self-contained airflow architecture enables reliable Class 5 performance even in ISO Class 8 (100,000) ambient environments, provided intake air is free of oil mist, corrosive gases, and excessive humidity.
