World first! –– flame extinguished automatically by vibration sensor
The flame is automatically extinguished when the new built-in sensor detects vibrations.
Instruments are completely safe during severe shaking caused by earthquakes.
Multimode automatic gas leak check
The fuel gas pipes inside the instrument gas controller are automatically checked
for gas leaks when the power is turned on and when the flame is extinguished.
Should a gas leak be detected, a warning buzzer sounds and a warning is
displayed on the screen.
Flame-retardant materials
UL 94V-0-rated flame-retardant materials are
used for the instrument external covers and
atomizer unit. This superior design pays due
consideration to safety.
Safe ignition switches
The switches perfectly fit finger contours and are
positioned near the window.
To prevent inadvertent operation, both switches
must be pressed simultaneously to start ignition.
Durable pipes and reliable couplings
All pipes are selected for durability and
used with highly reliable couplings.
Clear window
The large window permits observation of the
flame, and the burner can be easily accessed
through the large opening.
The window closes when released to eliminate
the chance of it being left open.
Automatic flame ignition and extinguishing
Flame ignition and extinguishing operations are extremely simple. The Air-C
