Description
Part number 073691, this Air Relief Vent Screen Cap serves as a direct replacement for Pentair SMBW Series filter systems. Seated atop the vent tube, it acts as a barrier against debris intrusion while still permitting trapped air to exit the system, which is critical for sustaining proper filter pressure and operation. Routine checks and timely swaps of this vent screen cap play a key role in keeping your pool’s filtration running at peak capacity for years to come.
