Product Features
1. Advanced Containment Technology
-
Negative pressure design: Maintains -15Pa to -30Pa gradient to prevent dust escape
-
Triple-stage filtration: Combines G4→F8→H14 filters for 99.995% particle retention
2. Precision Process Control
-
Dual 1.5KW fans: Ensure stable airflow (0.45±0.1m/s) during material transfers
-
Real-time monitoring: Touchscreen displays differential pressure, wind speed, and filter status
3. GMP-Compliant Construction
-
304 stainless steel: Resists disinfectants and prevents particle shedding
-
Seamless welds: Eliminate contamination traps per EU GMP Annex 1
4. Operational Safety
-
Automatic alarms: Trigger for pressure deviations or filter saturation
-
Emergency stop: Instantly halts operations if containment is compromised

FQAs
Q1: How does the negative pressure system prevent hazardous powder exposure?
The booth maintains -15Pa to -30Pa pressure gradient with dual 1.5KW fans, creating inward airflow that contains 99.9% of particles ≥5μm. This exceeds OSHA 29 CFR 1910.134 requirements for hazardous drug handling.
Q2: What makes your H14 filter more effective than standard HEPA?
Our MRJH H14 filters are MPPS-tested at 0.12μm (vs standard 0.3μm), capturing 99.995% of particles - critical for potent compounds like cytotoxics. Includes DOP test ports for routine validation.
Q3: Can the system handle continuous weighing of multiple APIs?
Yes, the 304 stainless steel interior and flow equalization membrane prevent cross-contamination during product changeovers. Touchscreen logs each session for 21 CFR Part 11 compliance.
