Posted on: 02/12/2025
The Dwyer ADPS-03-2-N-C monitors and controls differential pressure in cleanrooms, hospitals, and operating rooms. Durable mechanical design, easy installation, with early warning for pressure deviations.
Dwyer ADPS-03-2-N-C – Reliable Differential Pressure Control for Cleanrooms and Hospitals
In controlled environments such as cleanrooms, hospitals, and operating theaters, maintaining stable differential pressure between zones is critical. Proper pressure management ensures air quality, prevents cross-contamination, and complies with international standards like GMP, ISO 14644, and WHO-GMP.
For precise monitoring, engineers rely on the Dwyer ADPS-03-2-N-C – a compact yet essential mechanical differential pressure switch.
1. Why Differential Pressure Control Matters
In cleanroom HVAC systems, air pressure must be maintained at either positive or negative levels depending on the function of the area:
-
Operating rooms and sterile compounding areas: Positive pressure prevents dust and bacteria from entering.
-
Isolation rooms and biological laboratories: Negative pressure prevents contaminated air from escaping.
Even minor pressure fluctuations can disrupt airflow patterns, affecting safety and production quality. The Dwyer ADPS-03-2-N-C monitors and triggers alerts if pressure exceeds preset limits.
2. Introduction to Dwyer ADPS-03-2-N-C
The Dwyer ADPS-03-2-N-C is part of the ADPS Differential Pressure Switch Series, renowned globally for HVAC measurement and monitoring.
Key Features:
-
Measurement Range: 50 – 500 Pa, suitable for medium to high differential pressure control.
-
Mechanical Operation: Requires no power, using a diaphragm and adjustable spring.
-
SPDT Dry Contacts: Easily integrates with alarms, control panels, or building management systems (BMS).
-
ABS Flame-Retardant Housing, IP54: Durable in harsh environments.
-
Field-Adjustable Setpoint: Convenient tuning directly on the device.
