A2G-mini differential pressure gauge for ventilation and air conditioning WIKA

Description

The A2G-mini differential pressure gauge for ventilation and air conditioning from WIKA is used for measuring the differential pressure of gaseous and liquid media.

The model A2G-mini differential pressure instrument is used to monitor the differential pressures of filter units in small and medium-sized central air-conditioning systems. Further examples of applications are in industrial air extraction and dust extraction units and in the cleanroom industry. Its compact design and mounting plate allow optimum integration into ventilation equipment enclosures.

The pure metal construction – with stainless steel housing and copper alloy measuring system and movement – ensures maximum hygiene. Thanks to its silicone-free materials, the instrument can also be used in the painting industry and its applications.

The high IP68 ingress protection and UV-stabilised window also allow outdoor operation.
