Air Intake Check Valve for Praher Counter-Current Unit

The air intake check valve is an essential safety component of counter-current installations where the air supply opens below the water level. The valve lets air through in one direction only – into the counter-current unit – and automatically closes when the air flow stops, thereby preventing the siphon effect and the backflow of water into the air distribution or blower.

The valve from Praher is a proven and reliable solution compatible with most standard air supplies of counter-current units. The durable material withstands continuous contact with pool water and the air mixture.

Installation of the check valve is simple and is carried out in the air supply pipe at the point where backflow is a risk. Regular checking of the valve’s functionality is part of the standard service of the counter-current system.
