Product Introduction:
When the biogas pressure increases beyond the set pressure (usually around 2000 Pa), the biogas is automatically exhausted through the protector.
When biogas pressure is insufficient to meet demand, a negative pressure is created between the slurry and the gas holder (the function of the pressure-increasing fan). When the negative pressure reaches the set pressure (usually set to -300Pa), air is supplied to the tank through a protector to prevent damage to the gas holder and tank.
