Reverse osmosis water storage tank – 2.2 gallons

The 2.2-gallon (≈8 liters) storage tank is designed to hold purified water from a reverse osmosis system. It is an essential component of any household RO system, ensuring steady outlet pressure and a reserve supply of clean drinking water for convenient use.

The tank has an internal dual-chamber structure (air and water), separated by a high-quality elastic diaphragm that maintains pressure and prevents water stagnation. The carbon steel housing features a corrosion-resistant coating, and only food-grade butyl rubber is in contact with the stored water, ensuring purity.
