Description
Honeywell FK06-3/4AA is a compact water filter with pressure reducer, designed to protect domestic and utility water installations against mechanical impurities and the effects of excessively high pressure. The model with a 3/4" connection combines the functions of pre-filtration, filter screen rinsing, and pressure stabilization, thereby supporting effective water treatment and the safe operation of the entire water filtration system. It is a practical solution upstream of devices such as fittings, water heaters, softeners, or a reverse osmosis filter.

Filtration and pressure control in one device
The FK06 filter belongs to the group of filters with filter screen rinsing. During normal operation, the device continuously filters water, retaining mechanical impurities on the screen, such as rust, sand, fibers, and hemp shives, as well as other fine particles present in the installation.
The built-in pressure reducer protects the installation against the negative effects of excessive pressure. At the same time, it helps reduce water consumption and improves the operating conditions of installation components located further downstream in the system.
How does filter screen rinsing work?
In the Honeywell FK06-3/4AA model, impurities retained by the filter screen and sediment collected at the bottom of the housing are discharged outside the filter by opening the ball valve located in the lower part of the housing. This solution simplifies operation and helps keep the filter ready for further use.
An important advantage of this design is that filtered water is supplied even during rinsing, which increases everyday convenience.
The filter must be installed in a horizontal position, with the bowl facing downward. This installation method is important for the proper operation of the filter and pressure reducer.
Key features and benefits
- Simple installation
- Setting visible directly on the adjustment knob
- Adjustment spring mounted without contact with water
- Replaceable valve insert made of high-quality materials
- Filtered water supplied even during rinsing
- The regulator balances inlet pressure without affecting outlet pressure
- Transparent impact-resistant filter bowl allows observation of the contamination level
- Replaceable filter insert and filter bowl
- All materials have a hygienic certificate
- All materials have KTW approval
- The filter meets TÜV LGA requirements for low flow noise, Group 1 without restrictions
Compact design for places with limited space
Thanks to its small dimensions, the filter can be used wherever installation space is limited. This is an important advantage in service cabinets, near meters, in technical rooms, and wherever easy integration into an existing installation matters.
The transparent, impact-resistant housing makes it easy to monitor the contamination level on an ongoing basis. The user can quickly assess when rinsing should be carried out, without the need to dismantle the device.
Application in a water installation
Honeywell FK06-3/4AA works well as a pre-filter in cold water installations where simultaneous protection against mechanical impurities and pressure stabilization are required. It is a good choice upstream of devices sensitive to sediment and pressure fluctuations, as well as an element preparing water for further treatment stages.
In practice, such a water filter can be an important protective element for fittings, taps, valves, washing machines, dishwashers, water heaters, softeners, as well as installations in which an RO filter or a complete reverse osmosis system operates.
Set contents
- Honeywell FK06-3/4AA water filter with pressure reducer
- Prematlak pressure gauge
- Pressure gauge connection: 1/4" male thread
- Pressure gauge operating range: 0-10 bar
Operation and use
Daily operation of the device is convenient thanks to the combination of a filter and pressure reducer in one housing. The pressure setting is visible directly on the adjustment knob, making it easier to control the settings. Additionally, the regulator balances inlet pressure without affecting outlet pressure, which supports stable installation operation.
The design solutions used in this model increase durability and operational safety. The adjustment spring is mounted without contact with water, and the replaceable valve insert is made of high-quality materials. The device also provides the option of replacing the filter insert and the filter bowl.

Questions
What is the Honeywell FK06-3/4AA used for?
It is a water filter with a pressure reducer that retains mechanical impurities present in the installation and at the same time protects it against the effects of excessively high pressure.
What impurities does the FK06-3/4AA Honeywell water filter with pressure reducer retain?
The filter retains on the filter screen, among others, rust, sand, fibers, and hemp shives, as well as other fine mechanical impurities present in the installation water.
What does filter screen rinsing involve?
After opening the ball valve in the lower part of the housing, impurities collected at the bottom are discharged outside the filter. This makes it easier to keep the device in good operating condition.
Does the filter stop supplying water during rinsing?
No. One of the important features of this model is the supply of filtered water even during rinsing.
What is the pressure adjustment range?
The pressure setting range is from 1.5 to 6 bar. The setting is visible directly on the adjustment knob.
In what position should the filter be installed?
The device should be installed in a horizontal position, with the bowl facing downward. This position is required for the proper operation of the filter.
Is the pressure gauge included in the set?
Yes. The set includes a Prematlak pressure gauge with a 1/4" male thread and an operating range of 0-10 bar.
Is the filter suitable for places with limited installation space?
Yes. The compact dimensions of the device allow it to be used wherever the available installation space is limited.
Can the FK06-3/4AA Honeywell water filter with pressure reducer work with other water treatment devices?
Yes. As a pre-filter and pressure reducer, it can help protect downstream installation components such as softeners, fittings, or systems using a reverse osmosis filter.
