DPG-A Differential Pressure Gauge for Shelters: Pressure Monitoring in Protected Facilities
Maintaining the correct pressure differential is one of the key operational requirements for civil defence shelters, bunkers, safe rooms and other protected facilities. The DPG-A Differential Pressure Gauge is designed to measure and continuously monitor the differential pressure between protected shelter compartments—such as decontamination chambers and airlocks—or between the protected interior and the outside environment. According to the manufacturer, differential pressure monitoring is a critical part of the protection layer in shelter ventilation systems.

Purpose of the DPG-A Differential Pressure Gauge
According to Shelter-Shop, the DPG-A is intended for continuous monitoring of differential pressure in protected facilities. The instrument measures the pressure difference between two points within a ventilation or shelter system, allowing operators to verify that the required pressure conditions are maintained.
The manufacturer specifically states that the gauge is suitable for monitoring:
shelter compartments;
decontamination chambers;
airlocks;
pressure difference between the protected area and the outside environment.
The product page notes that continuous monitoring of overpressure is an essential element of the protection concept in shelters.

Operating principle
The DPG-A measures differential pressure, meaning it displays the pressure difference between two connected measuring points rather than the absolute pressure at a single location.
Within protected ventilation systems, differential pressure monitoring allows operators to verify that:
the protected area maintains positive pressure;
air flows in the intended direction;
filtration and ventilation equipment operates under the required conditions.
According to the manufacturer, this monitoring function supports the operation of shelter ventilation systems and helps maintain the designed protection level.
Application in protected facilities
Based on the manufacturer's description, the DPG-A is intended for installation in facilities such as:
civil defence shelters;
bunkers;
protected rooms;
decontamination chambers;
airlocks;
protected ventilation systems.
Its role is to provide continuous visual indication of differential pressure during system operation.

Importance of differential pressure monitoring
Shelter-Shop states that differential pressure monitoring is a critical component of shelter protection systems.
Monitoring enables operators to observe pressure conditions between protected and unprotected areas, helping verify that ventilation equipment is maintaining the required operating conditions.
The manufacturer identifies this function as an important part of the overall protection concept used in shelters and protected facilities.
Integration with shelter ventilation systems
The DPG-A is designed as part of an integrated shelter ventilation system.
According to the manufacturer, the gauge is used together with ventilation and filtration equipment to provide continuous pressure indication during system operation.
Its function is measurement and monitoring rather than air movement or filtration.
