The ROT-10 is a high-capacity, 40-liter (10-gallon) pressure tank for standard reverse osmosis systems, processing 40 L/hr to supply pressurized, pure water for up to 10 people.
It operates up to 7 bar (100 psi) and 90 °C (194 °F), factory pre-charged with 100% nitrogen at 0.5-0.7 bar (7-10 psi) for stable performance.
Dimensions are 35.5 cm (14.0 inch) diameter and 44.2 cm (17.4 inch) height. This stand-model tank includes a durable plastic base for commercial and high-capacity residential use.
Product Overview
The ROT-10 is a 40-liter (10 gallon) diaphragm pressure tank engineered specifically as a high-capacity Reverse Osmosis (RO) drinking tank. Designed for robust performance in small food shops, large offices, and extended households, the ROT-10 securely stores purified water and delivers it into the plumbing system with controlled, steady pressure.
ROT-10 is ideal for commercial applications. Its highly hygienic internal design separates the stored water from the compressed gas and completely prevents water from making direct contact with the internal metallic tank shell. Utilizing an FDA-approved polypropylene liner and a DIN 4807-compliant butyl rubber diaphragm, the ROT-10 ensures safe operation, delivering cleaner, fresher, and better-tasting water while maintaining a tasteless water zone absolutely free of any rubber or plastic smells.
Manufactured with premium materials and holding top-tier certifications including NSF58, CE, and IAPMO, Aquasky RO tanks are produced in ISO 9001:2008 registered facilities to deliver a long service life, dependable performance, and the safest drinking-water compatibility on the market.

Key Features & Design Advantages
How the RO-PLUS Pressure Tank Works
ROT-10 stores supplemental water securely between the butyl rubber diaphragm and the polypropylene liner, while the nitrogen-filled air chamber maintains constant system pressure. When a drinking tap or coffee maker is activated, the compressed nitrogen pushes the purified water into the system at a controlled pressure.
This specialized design ensures stable performance, completely separates the water from the metal shell, and maintains a clean water zone that is completely free of rubber or plastic odors.

Frequently Asked Question (FAQ)
Yes, the ROT-10 offers a large 40-liter (10-gallon) capacity and a 40 liters per hour output. This makes it the ideal standard reverse osmosis tank for small food shops serving around 10 people.
No. The ROT-10 is designed to be entirely maintenance-free during its service life. We utilize a specialized brass cap with an internal O-ring that guarantees no air loss from the air vent.
Additionally, it is the only RO storage tank in the industry pre-charged with 100% Nitrogen, which naturally resists permeation and prevents pressure fluctuations caused by temperature changes.
AQUASKY invented the leak-safe technology applied to the stainless connector 18 years ago, setting the benchmark for drinking water tanks. Manufactured in an ISO 9001:2008 registered facility and holding top-tier certifications like NSF58 and CE, it is recognized as one of the safest pressure vessels in the market.
