Overview
The Sujing Antai AMB-40S Weighing Booth is an ISO Class 5 (ISO 14644-1) compliant local containment system engineered for high-integrity powder handling in pharmaceutical, biotechnology, and fine chemical manufacturing environments. It operates on the principle of unidirectional laminar airflow—generated by a variable-frequency-driven centrifugal fan bank—directed vertically downward across the working surface at a controlled velocity of 0.45–0.5 m/s. This airflow profile ensures continuous dilution and removal of airborne particulates generated during weighing, dispensing, or sampling operations, thereby maintaining operator protection, product integrity, and environmental control in accordance with EU GMP Annex 1 and USP requirements for non-sterile compounding and API handling.
Key Features
- Real-time air velocity monitoring with closed-loop inverter control: maintains consistent face velocity across the entire work area despite filter loading or ambient pressure fluctuations.
- Dual-stage differential pressure indication system: provides independent visual readouts for pre-filter, medium-efficiency filter, and H13 HEPA filter pressure drop—enabling predictive maintenance scheduling per ISO 14644-3 and IEST-RP-CC001.
- Acoustically optimized ductwork and vibration-damped fan mounting: reduces operational noise to ≤75 dB(A) at 1 m distance, meeting occupational health standards for prolonged operator exposure.
- Seamless stainless steel interior with radius-curved floor-to-wall transitions: eliminates cleaning dead zones and supports effective CIP/SIP validation protocols.
- Modular filter housing design: allows rapid, tool-free replacement of G4 pre-filters, F8 bag filters, and H13 HEPA modules without compromising structural integrity or requiring recalibration.
- Integrated LED lighting system delivering ≥500 lx uniform illuminance across the entire work surface—compliant with ISO 8596 and EN 12464-1 for precision visual tasks.
Sample Compatibility & Compliance
The AMB-40S accommodates standard laboratory containers—including glass vials, HDPE/PP bottles, stainless steel scoops, and disposable weigh boats—within its 1200 mm × 600 mm work surface. Its containment performance has been validated using tracer gas (SF₆) challenge testing per ISO 10648-2, demonstrating ≥99.99% particle retention efficiency for ≥0.3 µm particles. The unit meets structural and electrical safety requirements under GB/T 14710 (Chinese national standard for environmental adaptability of medical devices) and conforms to EMC Directive 2014/30/EU. Optional integration with facility BMS enables alarm forwarding and event logging aligned with FDA 21 CFR Part 11 data integrity expectations.
Software & Data Management
While the AMB-40S operates via embedded microcontroller-based logic without external PC dependency, its touch-panel interface logs timestamped operational events—including filter pressure anomalies, fan speed deviations, and door interlock status—for up to 30 days. Audit trail export is supported via USB port in CSV format, preserving user identity, action type, and time stamp to support GLP/GMP traceability. Optional RS-485 Modbus RTU output allows connection to centralized monitoring platforms for trend analysis of airflow stability and maintenance cycle adherence.
Applications
This weighing booth is routinely deployed in quality control laboratories for raw material verification, in R&D settings for formulation development involving potent compounds (OEL ≤10 µg/m³), and in production support areas for batch release sampling. Its robust construction and validated airflow profile make it suitable for handling cytotoxic agents, hormonal APIs, and nanomaterials where cross-contamination risk must be mitigated below detectable limits. It also serves as a primary containment solution during analytical balance calibration and reference standard preparation under ISO/IEC 17025-accredited conditions.
FAQ
What ISO classification does the AMB-40S achieve in operation?
It delivers ISO Class 5 (equivalent to Grade A per EU GMP Annex 1) cleanroom conditions within the primary work zone when operated with certified H13 HEPA filters and maintained per manufacturer-recommended service intervals.
Can the unit be integrated into a building management system (BMS)?
Yes—via optional RS-485 Modbus RTU interface, enabling remote status monitoring, alarm relay activation, and runtime data acquisition for compliance reporting.
Is the H13 HEPA filter certified to EN 1822-1?
All supplied H13 modules undergo individual DOP/PAO scanning per EN 1822-3 and are provided with test certificates indicating local penetration ≤0.005% at rated flow.
What maintenance documentation is provided upon commissioning?
A full IQ/OQ protocol package—including airflow uniformity mapping, filter integrity test records, illumination validation, and noise level verification—is delivered with each unit to support regulatory inspection readiness.
