The ROT-34 is an extra-large, 130-liter (34-gallon) pressure tank designed for commercial reverse osmosis systems, shops, and large restaurants, supplying pressurized water for up to 35 people.
It operates up to 7 bar (100 psi) and 90 °C (194 °F) and is pre-charged with 100% nitrogen (0.5-0.7 bar / 7-10 psi) for stable performance.
This stand-model tank, measuring 55.0 cm (21.7 in) in diameter and 79.2 cm (31.2 in) in height, includes a heavy-duty plastic base for sturdy, massive water storage in high-traffic commercial environments.
Product Overview
The ROT-34 is a 130-liter (34 gallon) diaphragm pressure tank engineered specifically as a high-capacity Commercial Reverse Osmosis (RO) drinking tank. Designed to process 130 liters per hour, the ROT-34 securely stores a massive volume of purified water and delivers it into the plumbing system with controlled, steady pressure.
ROT-34 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-34 ensures exceptionally 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 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-34 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)
Absolutely. The ROT-34 is a heavy-duty 130-liter (34-gallon) tank delivering 130 liters per hour. It is specifically designed to support demanding commercial setups like a 20-table restaurant serving roughly 35 people.
No. The ROT-34 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.
Yes. The ROT-34 uses a high-grade polypropylene liner and a butyl diaphragm made with FDA-approved materials, which completely prevents the water from ever making contact with the metal tank shell.
This guarantees a tasteless water zone with no rubber or plastic smells, making it perfectly safe for clean drinking water. Furthermore, the stainless steel connector is chemical-free and lead-free.
