1. Who Needs Differential Pressure Gauges in GMP Cleanrooms?

In GMP-compliant manufacturing facilities, maintaining pressure differentials between cleanroom zones is a mandatory requirement to control airflow and prevent cross-contamination. A differential pressure gauge is a commonly used device that continuously measures and displays pressure differences in a clear and visual manner.

Areas That Require Pressure Monitoring:

Airlock rooms: Connect clean and less-clean areas. Positive pressure is required to ensure airflow moves from clean → less clean.
Weighing rooms: High risk of airborne active ingredient particles; requires negative pressure to protect the external environment.
Manufacturing, filling, and packaging areas: Must maintain strict cleanliness levels, often with a cascading pressure system.

Without continuous pressure monitoring, airflow may reverse-causing contamination between cleanroom zones.

The Role of Differential Pressure Gauges in HVAC Systems:

Monitor one-way airflow: Ensure air moves from clean → less clean → dirty zones.
Provide timely alerts: Some gauges include alarms when pressure exceeds safe thresholds.
Comply with GMP/ISO 14644: Helps QA teams validate and audit environmental conditions.

Common Users of Differential Pressure Gauges:

HVAC engineers - responsible for designing and installing controlled environments.
QA/QC professionals - in charge of environmental monitoring and GMP compliance.
Investors or plant managers - who make equipment purchase decisions aligned with regulatory needs.

2. Common Types of Differential Pressure Gauges for GMP Applications

Depending on the level of control and budget, GMP facilities typically use one of three main types of differential pressure gauges:

Gauge Type	Features	Advantages	Limitations
Mechanical (dual needle)	Operates without electricity	Low cost, durable, easy to read, simple installation	No alarm feature, cannot store data
Digital	Digital display with sensors	High accuracy, integrated alarm and signal output	Higher cost, requires power supply
Integrated Sensor - BMS	Connects to BMS or PLC	Centralized monitoring, easy to manage multiple rooms	Requires advanced installation and system integration

Selection Suggestions Based on GMP Application:

Airlocks and auxiliary rooms: Mechanical gauges may suffice if data logging isn't required.
Weighing and filling rooms: Digital gauges with alarms are ideal to quickly detect risks of cross-contamination.
Large-scale factories with automated systems: Use BMS-integrated pressure sensors for centralized monitoring.

Note: Some HVAC consultants recommend installing both mechanical and digital gauges in critical areas to ensure redundancy and manual data verification when needed.

5. Frequently Asked Questions About Differential Pressure Gauges in GMP Cleanrooms

1. Is it mandatory to use differential pressure gauges in GMP cleanrooms?

→ Yes. According to GMP standards, areas with different cleanliness classifications (e.g., weighing rooms, airlocks, processing rooms) must monitor and record pressure differentials to ensure unidirectional airflow from clean → less clean zones and prevent cross-contamination.
Lack of pressure monitoring is considered a serious non-compliance issue during GMP audits.

2. What type of pressure gauge is best for a pharmaceutical weighing room?

→ Digital gauges with pressure alarm functions are the best option for weighing rooms, which require continuous monitoring, high accuracy, and immediate response to pressure changes.
Some facilities also integrate digital gauges with BMS/PLC systems to store data for audit and validation purposes.

3. How often should differential pressure gauges be calibrated?

→ At least once a year, or every six months depending on the facility's internal SOPs and risk classification of the monitored area.
Calibration ensures accurate readings and prevents false alarms or undetected pressure issues.
VCR offers on-site calibration services with GMP-compliant documentation.
