High pressure switch for water purification system

Overview

The AS-H high pressure switch is designed to monitor outlet water pressure in reverse osmosis systems and booster pump setups. It automatically shuts off the pump when the storage tank is full or when maximum pressure is reached, preventing over-pressurization and extending the life of your equipment. Perfectly suited for use with booster pumps like the LS-8050 and LS-8200.

Key Features

• Automatic shut-off – stops the pump when high pressure is detected

• Protects the pump and RO system from overpressure damage

• Maintains system efficiency and prevents water waste

• Compact and easy to install in most RO systems

• Durable and low maintenance for long-term reliability
