This ISTA 2-way Air Flow Controller splits a single pump input into two independently controllable outputs.
Type: two-way air flow controller
Inputs: one, from the air pump
Outputs: two, each independently adjustable
Splits one air pump output into two lines, each with its own flow control, on standard airline.
It divides the air a pump already produces; it does not add any. Two outputs from a small pump means roughly half the air at each.
Fit a check valve in each line above the water line. Without one, tank water siphons back down the airline into the pump when the power goes off.
Do not close both outlets fully while the pump is running — a diaphragm pump with nowhere to push works itself to death.
The two-way air flow controller. Airline and check valves are not included.
