Dwyer 2000-500PA measures low differential pressure for HVAC and cleanrooms. High accuracy and durability for airflow, filter, and room pressure monitoring.

Dwyer Magnehelic® 2000-500PA – Precision Low Differential Pressure Gauge for HVAC & Cleanroom Applications

The Dwyer Magnehelic® 2000-500PA is a highly sensitive mechanical differential pressure gauge designed for systems that operate at very low static pressures. Its accuracy, durability, and reliability make it an essential instrument for HVAC systems, cleanrooms, filtration monitoring, and industrial air handling processes.

1. Why Choose the 0–500Pa Pressure Range?

The 500Pa range is one of the most commonly used scales in low-pressure environments because it offers:

• High sensitivity, suitable for detecting even minor changes in airflow or pressure.

• Ideal performance in cleanrooms and ventilation systems, where precise pressure control is crucial.

• Early indication of clogged filters, air leakage, or reduced flow within ducts.

• Stable readings without frequent recalibration.

• Compliance with pressure control standards in ISO/GMP cleanrooms, laboratories, and healthcare facilities.

2. Where the 2000-500PA Is Commonly Used

HVAC & Ventilation Systems

• Monitoring differential pressure between supply and return air ducts.

• Tracking filter condition (HEPA, pre-filter, medium filter).

• Ensuring balanced airflow and system efficiency.

Cleanrooms & Healthcare Facilities

• Maintaining positive or negative room pressure.

• Supporting contamination control in pharmaceutical plants, hospitals, and electronics manufacturing.

• Ensuring compliance with cleanroom classifications.

Industrial & Environmental Applications

• Monitoring low-pressure pneumatic lines.

• Measuring pressure drop across dust collectors and air filtration units.

• Detecting leaks and abnormalities in air handling systems.

3. Key Advantages of the Dwyer Magnehelic 2000 Series

• High accuracy: ±2% of full-scale reading.

• Robust mechanical design: shock-resistant, vibration-resistant, and suitable for harsh environments.

• No power required: simple installation and maintenance.

• Easy-to-read dial: allows immediate visual inspection.

• Wide range of models and scales for different installation needs.

• Trusted globally for long-term stability and consistent performance.

4. Installation & Usage Guidelines

To ensure optimal accuracy and durability:

• Mount the gauge in a stable location with minimal vibration.

• Connect the High and Low pressure ports correctly according to airflow direction.

• Use clean and dry tubing to prevent moisture from entering the gauge.

• Perform calibration checks every 6–12 months, depending on usage conditions.

5. Conclusion

The Dwyer Magnehelic® 2000-500PA is the perfect solution for applications that require precise low-pressure monitoring. Its sensitivity and stability make it indispensable for HVAC systems, cleanrooms, industrial filtration, and air handling processes.
