How come there is no air produced from some air outlets of air tube?
This will depend on the kind of system you’re using. Some system are alternating therapy products. That means air alternates between each air outlet; therefore, wait for the complete cycle of the alternating phase. Other system are low-air-loss (static) therapy products, there should be a steady airflow coming out of air outlets unless if the system reaches their preset pressure level or please check if there is any kinked air hoses.
