Thermo Fisher Scientific Protect-1FD Vertical Flow Clean Bench

Overview

The Thermo Fisher Scientific Protect-1FD Vertical Flow Clean Bench is an NSF/ANSI 49–2022 Class I-certified laminar airflow workstation engineered for personnel and environmental protection during low-risk, non-sterile laboratory procedures. Unlike biological safety cabinets, this clean bench provides unidirectional vertical downflow of HEPA-filtered air across the work surface—ensuring particulate-free conditions while offering no containment for hazardous agents. Its core architecture employs a high-efficiency AAF HEPA filter (≥99.995% efficiency at 0.3 µm) in conjunction with a pre-filter that captures coarse particulates and aerosolized organic contaminants prior to final filtration. The vertical airflow path minimizes turbulence and cross-contamination between dual operators seated on opposite sides, making it ideal for applications such as sample preparation, media dispensing, electronic component assembly, and inert material handling where operator protection is secondary to product purity.

Key Features

• Vertically oriented laminar airflow system delivering uniform, low-turbulence air velocity across the entire stainless-steel work surface
• Motorized or counterbalanced 5 mm tempered glass sash with programmable positional memory and height-limit safety interlock—prevents operation outside certified sash range
• Real-time LCD display showing instantaneous air velocity (m/s) across eight discrete fan-speed settings, enabling precise process alignment with ISO 14644-1 Class 5 (100) performance criteria
• Germicidal UV-C lamp (254 nm) with programmable timer, cumulative usage-hour tracking, and fail-safe interlock that disables UV emission whenever the sash exceeds safe opening height
• Integrated pre-filter, dual splash-proof 120 V AC outlets, and dedicated PAO upstream test port compliant with EN 1822 and ISO 14644-3 for quantitative HEPA filter integrity verification
• 304 stainless-steel work surface with seamless welds and radiused corners—resistant to corrosion, compatible with common disinfectants (e.g., 70% ethanol, hydrogen peroxide vapor), and validated for repeated cleaning under GLP/GMP hygiene protocols

Sample Compatibility & Compliance

The Protect-1FD supports open-vessel operations involving non-hazardous solids, liquids, and powders—including cell culture reagents, pharmaceutical excipients, semiconductor wafers, and calibration standards. It is not suitable for use with volatile organic solvents, radioactive isotopes, or biohazards requiring biosafety containment. Regulatory alignment includes full conformance with NSF/ANSI 49–2022 (Class I), ISO 14644-1:2015 (Class 5), and EU GMP Annex 1 (2022) requirements for cleanroom-grade environmental control in non-sterile manufacturing environments. All electrical components comply with UL 61010-1 and IEC 61000-6-3 EMC standards. Documentation packages include factory-assembled IQ/OQ protocols and traceable filter certification per EN 1822-3.

Software & Data Management

While the Protect-1FD operates without embedded microprocessor-based software, its hardware-level monitoring subsystem logs critical operational parameters—including UV exposure time, HEPA runtime hours, and fan duty cycle—for manual audit trail generation. The LCD interface provides immediate visual feedback on airflow status, sash position, and interlock activation events. For laboratories operating under FDA 21 CFR Part 11 or EU Annex 1 data integrity mandates, optional third-party digital loggers can be deployed via RS-485 or analog 4–20 mA outputs (available upon request) to capture timestamped environmental data synchronized with LIMS or MES platforms.

Applications

• Preparation of sterile-filtered buffers and diluents in QC labs supporting HPLC, GC, and dissolution testing
• Assembly and inspection of microfluidic devices and MEMS sensors under particle-controlled conditions
• Handling of hygroscopic or oxidation-sensitive reference standards in metrology and analytical calibration workflows
• Non-sterile compounding of topical formulations and ophthalmic solutions per USP
• Electronics prototyping involving solder paste application and PCB component placement
• Environmental sampling kit assembly for ISO 14644-2 compliance verification

FAQ

Does the Protect-1FD provide protection against biological agents or chemical vapors?
No. As a Class I clean bench per NSF/ANSI 49, it offers no operator or environmental protection from hazardous aerosols, vapors, or viable microorganisms. It is strictly intended for product protection only.
Can the HEPA filter be tested in situ without disassembly?
Yes. The integrated PAO upstream test port enables quantitative filter integrity testing using standard photometer or particle counter methodologies per ISO 14644-3 and EN 1822.
Is the unit compatible with 220–240 V power systems?
The standard Protect-1FD (117122004) is configured for 120 V AC, 60 Hz operation. A 230 V AC variant is available under separate catalog number—contact Thermo Fisher Technical Support for regional configuration options.
What maintenance intervals are recommended for optimal ISO Class 5 performance?
Pre-filters should be inspected weekly and replaced every 3–6 months depending on ambient particulate load; HEPA filters require annual integrity testing and replacement every 5–7 years under typical lab usage conditions.
Does the unit support integration into a centralized building management system (BMS)?
Analog output signals (4–20 mA for airflow velocity, relay contacts for alarm states) are available via optional I/O module—enabling BMS linkage for facility-wide environmental monitoring and predictive maintenance scheduling.
