QT820 Series Pneumatic Gas Mixer
The QT820 Series uses pneumatic control to blend two or three gases without an electrical power supply for the mixing function. Inlet filters protect the mixing components, and the compact unit can be wall-mounted. Mixing stops automatically if a gas supply is interrupted. Confirm the power requirements of any optional alarm or communication module.

Measurement conditions & notes
- Two-gas and three-gas blending using smilegaz mixing technology.
- The mixing function is pneumatic and does not require electrical power; hazardous area suitability must be confirmed for the exact configuration.
- No buffer tank is required, reducing installation space.
- Inlet filters help prevent contaminants from entering the mixer.
- Mixing stops automatically if a gas supply is interrupted.
- On-site mixing reduces the need to store multiple premixed gas cylinders.
- Compact, robust housing for wall mounting and maintenance access.
- Standard blend range 5~92%; custom models available.
