MEGA-2 is an essential part of a pressurized water system designed to reliably provide water pressure at a set level, specifically engineered for high-rise buildings and long-distance pressure support.
MEGA-2 has a total volume of 2 liters (0.5 gallons). Built for demanding environments, this tank features a robust maximum operating pressure of 16 bar. To ensure highly stable and reliable system performance over time, it is factory pre-charged with nitrogen gas.
With a highly compact diameter of 12.3 cm (4.8 inches) and a height of 21.4 cm (8.4 inches), this tank is ideal for point-of-use installations and tight spaces while delivering exceptional high-pressure performance.

Product Overview
The MEGA-2 is a 2-liter (0.5-gallon) diaphragm pressure tank that represents the peak of high-pressure water system stabilization. The tank works by storing supplemental water between a specialized liner and a diaphragm, while the pressurized air chamber creates a highly efficient supply cycle. This mechanical process significantly reduces the number of times your pump motor must start to keep the system pressure at the set level, extending the life of your equipment.
Constructed with a heavy-duty cold-rolled carbon steel shell and protected by a triple-grade blue paint coating, the MEGA-2 is built to endure. Inside, it utilizes a heavy-duty butyl rubber diaphragm designed to maintain constant water pressure within the system, ensuring the proper operation of appliances like dishwashers and washing machines, as well as robust flow for showering and bathing.
Equipped with a premium 304 stainless steel connector, the Aquasky MEGA-PLUS series provides an energy-saving, maintenance-free, high-water-pressure solution that you can depend on.

Key Features & Design Advantages
How the MEGA-PLUS Pressure Tank Works
The MEGA-2 stores supplemental water between the liner and the heavy-duty butyl rubber diaphragm. When a faucet is opened or an appliance demands water, the compressed nitrogen air chamber pushes the stored water into the system. This allows the system to meet low-volume water demands without immediately triggering the pump motor. By creating this efficient supply cycle, the tank minimizes pump cycling, stabilizes water pressure, and conserves energy.

Frequently Asked Question (FAQ)
The MEGA-2 is highly compact with a 2-liter (0.5 gallon) capacity, measuring just 12.3 cm in diameter and 21.4 cm in height. For shipping convenience, it is packaged with 4 pieces per standard box, with a total box net weight of 3.2 kg.
Yes. By storing supplemental pressurized water, the MEGA-2 reduces the number of times your pump motor needs to turn on for small water demands. This ensures your water system works far more efficiently and saves energy.
While many standard residential expansion tanks from competitors are rated for a maximum of 10 Bar (150 PSI), the MEGA-2 offers a robust 16-Bar high-pressure rating. This makes it vastly superior for high-pressure booster water systems, ensuring structural integrity even during severe pressure surges.
