Do we need RO for 500 ppm

Humidity and quality measurement when generating compressed breathing air

If these limit values ​​are not adhered to, considerable damage to life and limb can result. For example, too high a moisture content in the press / compressed air bottles can lead to the following:

Corrosion in the breathing air cylinders

The breathing air cylinder can be damaged by a creeping rust development without noticing it. When using the damaged bottles, unintended accidents can occur due to malfunctions.

Inhaling corrosive components is also harmful to health, so creeping personal injury can occur even without a malfunction.

Breeding ground for molds or other harmful bacteria

Too much moisture promotes the growth of mold or bacteria. Inhaling these can lead to pneumonia and other serious diseases.

Ice formation at low temperatures

During extreme diving in waters with temperatures close to freezing point, ice formation in breathing air cylinders can lead to dangerous situations. If the bottle outlet freezes under water, it can lead to death in the worst case.

Too high an oil content in pressurized / compressed air cylinders

Oil aerosols + particles: In addition to permanent breathing difficulties, inhaling oil mist can, in the worst case, lead to cancer. Aerosols also usually contain the smallest metal particles, which do not favor the situation.

For the proper monitoring of your breathing air in compressed air cylinders, we recommend:

FA 510/515 - Dew point sensors for humidity measurement in refrigeration dryers

for residual moisture measurement from -20 to 50 ° Ctd. New: With Modbus-RTU interface.


FA 500 - dew point sensor from -80 ° to 20 ° Ctd

Dew point sensor for various types of dryer with integrated display and alarm relay.


Particle counter PC 400 - mobile solution according to ISO 8573

The particle counter PC 400 up to 0.1 µm for compressed air and gases is the ideal mobile solution in a service case.


Residual oil measurement OILCHECK according to ISO 8573 - mobile solution

The residual oil sensor measures the residual oil content in vapor form in the compressed air. For the mobile solution, we offer a combination with the PC 400 + DS 500 mobile.
