Description
The 3/4" OTTONE pressure reducer with filter and pressure gauge is a practical component of a water installation that automatically lowers and stabilizes water pressure while helping protect pipes, fittings, and connected devices. The built-in stainless steel mesh filter traps mechanical impurities, and the pressure gauge makes it easy to monitor the setting on an ongoing basis. This is a particularly useful solution wherever safe water treatment, an efficient water filtration system, and protection of devices such as a water filter, reverse osmosis filter, or home reverse osmosis system are important.

Stable pressure and better installation protection
Model OT050412 has been designed for automatic pressure regulation in water supply installations. Its task is to limit excessive pressure and maintain more stable operating conditions for the entire system, even when fluctuations occur at the inlet.
As a result, the installation operates more predictably, and the risk of damage caused by sudden pressure surges is reduced. This is important both in standard domestic installations and in systems where more sensitive components responsible for water treatment operate.
Key product features
Automatic pressure regulation
The reducer automatically lowers and stabilizes water pressure in the installation. Regardless of changes in inlet pressure, it helps maintain optimal operating conditions for the water system.
Precise pressure gauge
The integrated pressure gauge allows accurate pressure monitoring and convenient checking of the setting. This solution increases user comfort and makes it easier to assess installation performance.
Built-in stainless steel mesh filter
The reducer is equipped with a mesh filter made of stainless steel. Its task is to trap mechanical impurities present in the water, which helps protect the installation and connected devices. The filter can be easily removed and cleaned, making daily use easier.
Durable materials and reliable operation
Solid workmanship and the use of resistant materials translate into long service life and effective operation even in demanding working conditions.
Stable operation thanks to the diaphragm
A special diaphragm compensates for larger pressure surges, stabilizing the operation of the entire system and helping minimize the risk of failures.
Easy installation
The device has been designed so that installation proceeds smoothly and without unnecessary complications. It is a good choice both when upgrading an existing installation and when building a new system.
Why choose this water pressure reducer?
- protects the installation against the effects of sudden pressure surges,
- helps extend the service life of fittings and devices connected to the installation,
- combines pressure reduction, mechanical filtration, and operating parameter control,
- makes maintenance easier thanks to the mesh filter that is easy to clean,
- allows convenient pressure monitoring with the pressure gauge,
- supports safer operation of systems using a water filter, osmosis filter, or osmosis membrane.
Stable, controlled pressure means not only greater installation safety, but also more predictable operation of the entire system. In practice, this means a lower risk of failures, fewer operating problems, and easier system maintenance.
Application
The OTTONE 3/4" pressure reducer is suitable for water supply installations and domestic hot water systems. It can be used wherever installation protection against excessive pressure and improved operating conditions for end devices are required.
This is a practical solution for houses, apartments, and water tapping points, as well as for installations where elements such as a water filtration system, reverse osmosis, or a reverse osmosis filter operate and require more stable supply parameters.
To maintain high operating efficiency, it is advisable to periodically check the pressure gauge readings and clean the stainless steel mesh filter. Regular maintenance helps maintain proper flow and long device service life.
Operation and everyday use
Operating the reducer is convenient and does not require complicated actions. The pressure gauge allows a quick check of the current pressure, and the mesh filter can be removed for cleaning, which limits the buildup of impurities in the system.
This combination of functions means that the device not only stabilizes installation performance, but also makes it easier to keep it in good condition for a longer time. It is an economical solution because it helps reduce operating costs and the risk of possible failures.
