The OTTOclean 5/4" water filter is designed for effective removal of impurities from water. It features a semi-automatic flushing system, making it ideal for both domestic and industrial use.
The 5/4" water filter with OTTOCLEAN OTTONE flushing is an efficient component of a water filtration system, designed for effective removal of mechanical impurities in domestic and industrial installations. The semi-automatic flushing model makes routine maintenance easier, supports efficient water treatment, and helps protect fittings, equipment, and subsequent filtration stages, including the more precise filter cartridge used in expanded systems.

The OTTOCLEAN filter with a 5/4" diameter has been designed for effective removal of impurities from water. This solution combines high build quality, high performance, and convenient operation, so it works well in both domestic and industrial applications.
The most important advantage of this model is the semi-automatic flushing system, which significantly simplifies use and reduces the time needed to clean the filter element. As a result, the water filter can operate efficiently for a long time, while routine maintenance remains quick and convenient.
The filter operates at temperatures up to 30°C and withstands pressure up to 16 bar, allowing it to be used in a wide range of installations. This makes it suitable wherever a durable and effective water filtration system based on the separation of mechanical impurities is needed.
A filtration accuracy of 90 µm allows for effective capture of mechanical impurities present in water. The filter requires a minimum pressure of 1.5 bar for efficient flushing, and the large filtration area and high flow rates translate into very good performance in everyday use.
The semi-automatic flushing function, carried out using brushes and a knob, makes it easy to keep the unit clean without complicated servicing.
The filter cartridge is made of materials valued for resistance and long service life: INOX stainless steel and polyamide. This construction supports reliable filter operation and allows for long-term use even in demanding conditions.
The solid construction of the entire body and accessories increases resistance to intensive use and helps maintain stable operating parameters.
The filter is equipped with a nickel-plated brass drain valve and a check valve included in the set. This solution increases ease of use, supports reliable operation, and makes flushing and routine maintenance easier.
The use of a stainless steel mesh filter cartridge translates into effective water purification from solid particles. It is a good choice as a pre-filter protecting further installation components and utility equipment.
The semi-automatic flushing system makes cleaning the filter simple and quick. This reduces the time needed for maintenance while also making it easier to keep the unit operating efficiently.
The OTTOCLEAN 5/4" model works well as a mechanical filter for protecting the water installation against impurities. It can serve as an important pre-stage where effective water treatment and protection of fittings, valves, equipment, and subsequent filtration components matter.
In practice, the filter can be used before more advanced water treatment solutions such as an osmosis filter, reverse osmosis filter, reverse osmosis system, or reverse osmosis, because it limits the flow of larger mechanical particles into later treatment stages.
For proper flushing, a minimum pressure of 1.5 bar is required. The unit operates at a maximum temperature of 30°C and a maximum pressure of 16 bar. The sewage connection size is 5/4".
The OTTOclean filter with a 5/4" diameter is a high-quality product designed for effective removal of impurities from water. Thanks to the semi-automatic flushing system, it is easy to use, which makes it ideal for both domestic and industrial use.
