Erlab Flow 714 Smart Vertical Laminar Flow Clean Bench

Overview

The Erlab Flow 714 Smart is a vertically oriented laminar flow clean bench engineered for precision sample protection in non-sterile but particle-controlled laboratory environments. Unlike biosafety cabinets, it provides unidirectional, HEPA- or ULPA-filtered air flowing vertically downward across the work surface—creating an ISO Class 5 (formerly Class 100) environment per EN ISO 14644-1:2015. This airflow architecture minimizes turbulence and cross-contamination, making it ideal for applications where operator protection is not required, but sample integrity against airborne particulates is critical. Designed for flexibility and integration into modern lab infrastructure, the Flow 714 Smart operates as a self-contained, ductless unit—eliminating the need for external exhaust systems or structural modifications. Its vertical laminar flow principle ensures consistent velocity uniformity (>0.3 m/s at work surface), validated through standardized anemometric mapping and particle challenge testing.

Key Features

• Smart optical interface with dynamic LED status band: Real-time visual feedback on airflow stability, filter saturation, and operational safety level—no manual calibration or software login required.
• Modular high-efficiency filtration system: Interchangeable HEPA H14 (99.995% @ 0.1 µm) or ULPA U17 (99.999995% @ 0.1 µm) filters, pre-filtered by G4 coarse media to extend service life.
• Optional integrated molecular filtration: Dual-stage activated carbon + chemisorptive media module removes volatile organic compounds (VOCs), aldehydes, and acidic gases—critical for sensitive cell culture, semiconductor wafer handling, and analytical sample prep.
• Ergonomic height-adjustable sash and work surface: Motorized vertical lift mechanism enables precise positioning between 1340 mm (minimum) and 1436 mm (maximum), accommodating seated or standing operation.
• Low-noise, energy-efficient EC motor-driven blower: Operates at ≤61 dB(A) at 1 m distance; power draw stabilized at 105–110 W under continuous duty cycle.
• Comprehensive alarm system: Audible and visual alerts triggered by airflow deviation (>±10% from setpoint), filter pressure differential exceedance, or sash position anomaly—fully traceable via internal event log.

Sample Compatibility & Compliance

The Flow 714 Smart supports a broad scope of non-hazardous, non-volatile sample types including mammalian and insect cell cultures, plant tissue explants, PCR setup, microbiological media pouring, microelectronics assembly, and pharmaceutical formulation staging. It complies with EN ISO 14644-1:2015 (cleanroom classification), EN 12464-1:2021 (lighting and ergonomics for indoor workplaces), and IEC 61000-6-3/6-4 (EMC immunity and emissions). While not certified for biological containment, its ISO Class 5 performance meets the environmental requirements specified in USP for low-risk compounding and ISO 13408-1 for aseptic processing support zones. Filter integrity is verified annually per ISO 14644-3 Annex B using dioctyl phthalate (DOP) or polyalphaolefin (PAO) challenge testing.

Software & Data Management

The Flow 714 Smart embeds firmware-level logging—not cloud-based software—with local storage of ≥10,000 operational events (e.g., runtime hours, alarm triggers, filter delta-P trends). All logs are timestamped, immutable, and exportable via USB-C port in CSV format for GLP/GMP audit trails. No remote connectivity or network interface is included by default, preserving data sovereignty and minimizing cybersecurity exposure—a design choice aligned with FDA 21 CFR Part 11 expectations for electronic records in regulated labs. Firmware updates are performed offline via signed binary packages distributed through Erlab’s authorized service portal.

Applications

• Tissue culture laboratories requiring consistent particulate-free environments for primary cell expansion and transfection protocols.
• Quality control labs performing non-sterile analytical sample preparation for HPLC, GC-MS, and elemental analysis.
• Semiconductor fabrication support areas where sub-micron particle exclusion is mandatory during photomask inspection or probe station loading.
• Food microbiology labs conducting colony isolation, selective plating, and enumeration without aerosol-generating steps.
• Academic research facilities deploying modular, reconfigurable clean workspaces across teaching and core labs without HVAC retrofitting.

FAQ

Does the Flow 714 Smart require external ductwork or exhaust connection?

No—it is a fully recirculating, ductless system. Approximately 70% of air is recirculated after HEPA/ULPA filtration; 30% is exhausted internally via carbon scrubbing (if molecular filter installed) or ambient dissipation.
Can this unit be validated for ISO Class 5 compliance in-house?

Yes. Erlab provides a certified validation kit—including calibrated particle counter, anemometer, and test protocol templates aligned with ISO 14644-1 Annex B—for user-performed qualification (IQ/OQ). Third-party certification is also supported.
What is the expected service life of the ULPA U17 filter under typical lab use?

Based on continuous operation (8 h/day, 5 days/week) and standard G4 pre-filtration, ULPA U17 filters typically last 3–5 years. Filter replacement intervals are tracked automatically and displayed via the Smart LED interface.
Is the molecular filtration module compatible with all Flow series models?

Yes—the same activated carbon + impregnated alumina cartridge format is standardized across the Flow Smart product line, enabling field-upgradeability without mechanical modification.
How does the Flow 714 Smart meet energy efficiency standards in EU laboratories?

It conforms to EU Ecodesign Directive (EU) 2019/1781 for local air treatment units, achieving an Energy Efficiency Index (EEI) of ≤0.85—well below the 1.0 threshold for Class A rating.
