Overview
The AIRTECH LC/GKF Series High-Efficiency Air Supply Unit is an engineered ceiling-mounted laminar airflow delivery system designed for controlled environments requiring strict particulate control—primarily ISO Class 3 to Class 5 cleanrooms used in pharmaceutical manufacturing, aseptic processing, semiconductor assembly, and biomedical research laboratories. It operates on the principle of unidirectional (laminar) airflow, where conditioned air passes through a certified high-efficiency particulate air (HEPA) or ultra-low penetration air (ULPA) filter—mounted in a bottom-access configuration—and is discharged uniformly into the clean zone via a diffuser faceplate. The unit integrates seamlessly into suspended ceiling grids and interfaces directly with supply ductwork via standardized flanges. Its structural architecture prioritizes mechanical stability, airflow uniformity, and long-term sealing integrity under continuous operation at rated static pressure differentials.
Key Features
- Bottom-loading HEPA/ULPA filter design enables rapid, tool-free replacement without disrupting ceiling infrastructure or requiring upstream duct disassembly.
- Three filter specification options: H13 (≥99.99% @ 0.3 µm), H14 (≥99.995% @ 0.3 µm), and liquid-seal (gel-seal) variants for enhanced gasket integrity in high-stability applications.
- Low initial resistance (≤230 Pa at rated airflow) minimizes fan energy demand and supports stable pressure cascade management across multi-zone cleanroom layouts.
- Modular aluminum housing with powder-coated finish ensures corrosion resistance, dimensional stability, and compatibility with ISO-standard cleanroom construction practices.
- Standardized flange interface (e.g., 200×200 mm to 630×250 mm) allows direct integration with rectangular galvanized steel or stainless-steel duct systems per EN 1507 and GB/T 17410.
- Diffuser faceplate engineered for airflow uniformity ≥85% across the discharge plane (per IEST-RP-CC002.3 test methodology), reducing turbulence-induced particle resuspension.
Sample Compatibility & Compliance
The LC/GKF Series is compatible with standard HEPA/ULPA filters conforming to EN 1822-1:2019 and GB/T 13554–2020 classification criteria. Units are dimensionally aligned with common cleanroom ceiling grid modules (600×600 mm and 1200×600 mm). All configurations support validation protocols required under EU GMP Annex 1 (2022), FDA Aseptic Processing Guidance (2004), and ISO 14644-3:2019 for airborne particle testing. Leak testing capability—via DOP/PAO scanning at the filter frame and housing perimeter—is facilitated by accessible gasket zones and optional integral test ports. Units are supplied with material certifications (RoHS-compliant aluminum alloys, non-outgassing sealants) and factory-applied filter integrity test reports (scan data included).
Software & Data Management
While the LC/GKF Series is a passive mechanical air distribution device (i.e., no embedded electronics or firmware), it is fully compatible with building management systems (BMS) and cleanroom monitoring platforms via external differential pressure sensors and airflow measurement stations (e.g., thermal anemometers or pitot arrays). Documentation packages include as-built installation drawings, filter change logs, and commissioning checklists aligned with ISO 14644-4:2022 Annex D for HVAC system qualification. For regulated environments, traceable records—including filter lot numbers, leak test timestamps, and maintenance signatures—can be integrated into electronic quality management systems (eQMS) compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements.
Applications
- Aseptic filling lines in sterile pharmaceutical production (e.g., vial, syringe, and cartridge filling suites).
- Class 100 (ISO 5) laminar flow hoods and isolators supporting cell therapy and mRNA vaccine development.
- Critical process areas in microelectronics fabrication where sub-100 nm particle control is mandatory.
- Research-grade biosafety level 2+ (BSL-2+) laboratories performing gene editing or viral vector production.
- Hospital pharmacy compounding centers meeting USP and environmental standards.
FAQ
What filter classes are supported by the LC/GKF Series?
H13 (EN 1822), H14 (EN 1822), and liquid-seal variants compliant with GB/T 13554–2020 Class III and IV specifications.
Is field balancing or airflow adjustment possible after installation?
Yes—integrated manual balancing dampers (optional) and calibrated anemometer ports allow post-installation verification and fine-tuning per ISO 14644-3:2019 section 8.2.
Does the unit comply with seismic or vibration-sensitive facility requirements?
The rigid aluminum chassis and reinforced mounting brackets meet IBC 2021 Seismic Design Category B provisions; additional vibration isolation mounts are available upon request.
Can the LC/GKF Series be integrated into a cleanroom that requires real-time particle monitoring?
Yes—the unit’s discharge plane is compatible with ISO 21501-4-compliant remote particle counters mounted downstream, and its structural geometry supports validated sensor placement per ISO 14644-2:2015 Annex C.
What documentation is provided for regulatory submission?
Factory test reports (filter efficiency, leakage, pressure drop), installation qualification (IQ) templates, and material compliance declarations (REACH, RoHS, non-volatile residue) are included in the delivery package.
