F50TD
ARKA
The F50TD 1.5 inch TX type plastic disc filter delivers manual cleaning filtration performance for medium-flow irrigation systems and commercial water treatment applications. Featuring a 1-1/2 inch BSP/NPT connection and a 300 cm² filtering surface area, this model handles flow rates up to 14 m³/h while maintaining a compact footprint. The TX series design prioritizes straightforward operation and durable construction, making it suitable for agricultural irrigation, commercial landscape systems, and light industrial water filtration installations.
Manufactured from polypropylene plastic, the filter housing resists corrosion from agricultural chemicals, fertilizers, and standard water treatment additives. The threaded closure system provides a secure seal and allows tool-free access for routine maintenance. Production follows ISO 9001 quality management protocols, and each unit carries CE certification for compliance with European safety and performance standards.
The F50TD operates on the depth filtration principle using a stack of precisely grooved polypropylene discs. During normal operation, water flows through the filter inlet and passes radially through the compressed disc stack from the outer surface toward the central core. The intersecting V-shaped grooves on each disc form a tortuous three-dimensional pathway that captures suspended solids, sand, silt, algae, and organic debris at the selected filtration grade.
The depth filtration design means particles become trapped throughout the full thickness of the disc stack rather than accumulating only on the surface, which extends the interval between cleaning cycles. When the pressure differential across the filter increases to a noticeable level — indicated by reduced flow or elevated pressure gauge readings — the operator initiates manual cleaning. This involves unscrewing the threaded lid, removing the disc cartridge, and rinsing the discs with clean water to remove accumulated contaminants. After reassembly, the filter returns to service.
The F50TD provides 300 cm² of total filtering surface area across its disc stack. This substantial surface area increases dirt-holding capacity, reducing the frequency of required cleanings compared to smaller filter models. For commercial operations, this means less maintenance labor and longer uninterrupted run times between service intervals.
The filter incorporates a threaded closure mechanism that creates a positive seal against the internal gasket. This design ensures watertight performance at the full 8 bar working pressure rating while remaining easy to open and close by hand, without requiring specialized tools or keys.
Users can select from four filtration grades — 40, 80, 120, and 150 mesh — to match specific water quality conditions and downstream equipment protection needs. Coarser meshes handle high sediment loads with lower pressure drop, while finer grades protect precision irrigation components such as drip emitters and micro-sprays.
The filter body and disc elements are constructed from polypropylene plastic, a material selected for its resistance to common agricultural chemicals, liquid fertilizers, and chlorine-based water treatments. This material choice supports long service life in outdoor agricultural and industrial environments.
The filter housing includes two pre-installed ports for pressure gauge connections on the inlet and outlet sides, enabling continuous monitoring of pressure differential as an indicator of filter condition. An auxiliary drain connection facilitates routine flushing and simplifies the maintenance process.
With dimensions of 280 × 205 × 139 mm and a weight of 1.01 kg, the F50TD fits into equipment enclosures, pump stations, and irrigation valve boxes with limited available space. The lightweight construction simplifies handling during installation and maintenance procedures.

The F50TD 1.5 inch disc filter serves across a range of commercial and industrial applications. In agricultural settings, it protects drip irrigation systems, sprinkler networks, and greenhouse watering systems from sediment damage, supporting crop production and nursery operations. Commercial landscape contractors use these filters in park irrigation systems, golf course turf management, and commercial property grounds maintenance.
Industrial applications include cooling water pre-filtration, process water treatment, and equipment wash-down systems where moderate flow rates require consistent sediment removal. Municipal public works departments deploy these filters in community gardens, roadside landscaping, and urban green infrastructure projects. The filter's manual operation and durable construction make it appropriate for installations where automated systems are not required or where power access is limited.
The F50TD model supports a maximum flow rate of 14 m³/h (approximately 62 gpm). Actual performance varies based on source water quality, the selected filtration mesh grade, and system operating pressure. The 300 cm² filtering surface area helps maintain flow rates as sediment accumulates.
Cleaning frequency depends on source water quality and the filtration grade in use. Systems with high sediment loads may require weekly cleaning, while installations with cleaner source water may only need monthly maintenance. Monitoring pressure differential across the filter provides the most accurate indicator of when cleaning is necessary.
For standard drip irrigation systems, 120 mesh is the commonly recommended filtration grade to protect drip emitters from clogging. For systems with very small flow path emitters or micro-spray nozzles, 150 mesh provides finer filtration. Systems with high sediment loads may benefit from a two-stage filtration approach using a coarser pre-filter followed by a finer disc filter.
Yes, the F50TD filter connections are designed to accommodate both BSP (British Standard Pipe) and NPT (National Pipe Thread) thread standards. This compatibility simplifies integration into different regional piping systems and commercial procurement specifications across international markets.
The F50TD TX type disc filter has a maximum working pressure rating of 8 bar (approximately 116 psi). This rating covers the operating pressure range of most agricultural and commercial irrigation systems. The threaded closure with gasket seal maintains pressure integrity across the full rated range.
