1. This kind of equipment is fully enclosed and does not contact with air, and all over-current parts are made of food-grade 304 stainless steel, which is hygienic and corrosion-resistant, ensuring the cleanliness and hygiene of water quality.

2. This equipment can not only prevent negative pressure, but also make the laminating time long and stable. The energy-saving effect is obvious.

3. It can automatically compensate the pressure difference caused by the pressure drop of the municipal pipe network during the peak hours.

Main Application

In areas where the municipal pipe network has sufficient water resources, is relatively stable or fluctuates little.
