## Summary description

Mechanical filter VIESSMANN Epurion A25-2 (S), MPN 7511791, is a compact mechanical water filtration unit designed to remove suspended solids and particulate matter from water systems. Intended for pre-filtration in residential or light commercial heating and domestic water installations, it helps protect boilers, heat exchangers and valves from debris and sediment, improving system longevity and reliability.

## Long description

The VIESSMANN Epurion A25-2 (S) mechanical filter is a compact inline device designed for mechanical filtration of water in heating and domestic water systems. It removes suspended solids and particulate matter to protect boilers, heat exchangers and valves from debris and sediment. The unit is intended primarily for pre-filtration in residential and light commercial installations where reliable coarse filtration is required to maintain equipment performance and reduce maintenance frequency.
Advantages
The mechanical construction provides reliable removal of visible particles and sediment without chemicals or electronic components. Its compact design allows installation in confined spaces of boiler rooms or plant cabinets. The filter housing and internal components are designed for easy access and cleaning, reducing downtime and routine maintenance effort. Materials and flow path are selected to minimise pressure loss while maintaining effective particle capture.
Suitable for
 Pre-filtration of water supply to boilers and heating circuits
 Protection of heat exchangers and valves in residential systems
 Light commercial hydronic installations
 Systems requiring coarse particle removal and sediment separation
Key specifications
 Type: mechanical inline water filter for suspended solids removal
 Installation position: inline, suitable for compact boiler room layouts
 Primary function: removal of particulate matter and sediment from water
 Construction: serviceable housing with removable strainer element for cleaning
 Hydraulic characteristics: designed to minimise pressure drop at typical flow rates for residential and light commercial systems
 Materials: corrosion-resistant wetted parts suitable for heating and domestic water applications
How to use
Install the mechanical filter in the feed line to the boiler or heating circuit according to the system flow direction. Ensure shut-off valves are fitted upstream and downstream to allow isolation for maintenance. Periodically isolate the unit and remove the strainer element to inspect and clean accumulated debris. After cleaning, reassemble the housing and restore system flow, checking for leaks and verifying normal pressure and flow conditions. Follow local regulations and the system manufacturer's guidelines for installation and commissioning.
Usage recommendations
For reliable performance, perform visual inspections at regular intervals and clean the strainer when sediment accumulation affects flow or when pressure drop increases beyond typical operating levels. Use in combination with chemical water treatment and finer filtration stages if required by system specifications. Ensure compatibility with the system's operating temperature and pressure ranges.
