What is negative pressure?
When the exhaust air volume in the space is greater than the air intake volume, the space is in a negative pressure state, the air outside flows into the interior and is discharged through the exhaust outlet for centralized treatment.

When to choose negative pressure?
When the external environment is safe, but toxic and harmful gases are generated inside, negative pressure is preferred.

CPFG is divided into three working modes: manual mode, bypass mode and automatic mode. Turn the mode selector switch to the corresponding mode, at the same time, HMI face change will switch to the corresponding mode. The operation instructions of each mode are as follows:
 
Manual mode: only for emergency use, only the HMI "STOP" button/ESD signal/Cut-off signal can stop the output of safety power supply.
Bypass mode: Only can be used in safe area, make sure no dangerous gas and fire alarm start the safety power supply.
Auto mode: Can be used for normal use in dangerous area.
