The ARKA F75TD 2.5 inch t-type disc filter is engineered for medium-to-high flow water filtration in agricultural irrigation, municipal landscape, and industrial water systems. With a maximum flow rate of 40 m³/h and a pressure rating of 10 Bar, this filter handles the demands of commercial irrigation networks and process water circuits. The T-type housing provides a straight-through flow path that minimizes head loss while accommodating a larger disc stack for extended service intervals between cleanings.
The T-type configuration positions the disc element vertically within the housing, with water entering through one side port, passing upward through the disc stack, and exiting through the opposite side port. This straight-through flow pattern reduces turbulence compared with angled designs, contributing to lower pressure drop at higher flow rates. The vertical disc stack orientation also promotes uniform particle deposition across the filter surface, delaying clogging and extending the time between maintenance cycles.
The filter housing is available in two body styles: black opaque PP plastic and transparent PC plastic. The transparent housing option allows visual inspection of the disc element condition without disassembly, enabling maintenance teams to assess fouling levels and schedule cleaning proactively.
The F75TD supports six filtration grades: 40, 80, 120, 150, 200, and 300 mesh. This range covers applications from coarse pre-filtration (40 mesh for sand and large debris) to fine protection (300 mesh for precision drip emitters and micro-sprinklers). Each grade corresponds to a specific particle retention size, allowing system designers to match filtration precision to water source quality and downstream equipment requirements.
For reference, 40 mesh retains particles approximately 400 microns and larger, while 300 mesh retains particles around 50 microns and larger. Selecting the appropriate grade involves balancing filtration effectiveness against pressure drop and cleaning frequency considerations.

BSP (British Standard Pipe) and NPT (National Pipe Thread) threaded connections are available for systems using threaded pipe fittings. These connection types suit retrofits and installations where existing piping uses threaded joints. Both BSP parallel and NPT tapered threads provide reliable sealing when installed with appropriate thread sealant or tape.
VIC (Victaulic-style) clamp connections enable rapid installation and disassembly using grooved pipe ends and mechanical clamps. This connection type reduces installation time in large-scale projects and simplifies filter removal for maintenance or replacement. VIC connections are commonly specified in municipal and industrial piping systems where serviceability and installation speed are priorities.
Flange connections provide a robust, bolted joint suitable for higher pressure systems and permanent installations. Flanged connections distribute stress across the joint face, making them appropriate for systems with pressure fluctuations or vibration. This connection type is standard in many industrial water treatment plants and large agricultural pump stations.
In row crop, orchard, and vineyard irrigation systems, the 2.5 inch t-type disc filter protects drip lines, micro-sprinklers, and spray nozzles from sediment and organic matter carried in canal, pond, or well water. The 40 m³/h flow capacity covers medium-sized irrigation zones serving several hectares per filter unit. For larger operations, multiple filters can be installed in parallel to handle higher total flow rates.
Municipal parks, highway medians, golf courses, and commercial landscape developments benefit from the filter's combination of flow capacity and compact footprint. The transparent housing option is particularly useful in landscape maintenance contracts, allowing grounds crews to assess filter condition during routine inspections without tools or disassembly.
In industrial settings, the filter serves as pre-filtration for cooling towers, heat exchangers, spray nozzles, and process water loops. The 10 Bar pressure rating supports typical industrial water system pressures, while the PP plastic housing resists corrosion from treated water and mild chemical additives. Multiple filtration grade options allow engineers to specify the appropriate level of protection for each application.
The transparent PC housing option allows operators to visually inspect the disc element color and debris accumulation without opening the filter. This capability reduces unnecessary disassembly and cleaning cycles, as maintenance can be scheduled based on actual fouling condition rather than fixed time intervals. For facility management teams overseeing multiple filter units across a site, this feature reduces labor time and maintenance costs.
The transparent housing is constructed from polycarbonate (PC) material, which offers high impact resistance and optical clarity. Users should verify pressure ratings and chemical compatibility for their specific application, as PC material may have different temperature and chemical resistance characteristics compared with the black PP housing option. Consult the specification sheet for detailed performance limits of the transparent variant.
T-type disc filters have a straight-through flow path with the disc element oriented vertically, while Y-type filters use an angled body. T-type designs generally offer lower pressure drop at higher flow rates and accommodate larger disc stacks for longer service intervals. Y-type filters are more compact and better suited for installations with limited space.
Choose 40 mesh for coarse pre-filtration when water contains large debris such as sand, leaves, or organic fragments. Choose 200 mesh or finer for protecting drip emitters, micro-sprinklers, or precision nozzles where small particles can cause clogging. Always match the filtration grade to the smallest passage size in your downstream equipment.
The pressure rating may vary between the black PP housing and transparent PC housing versions. Refer to the specific product datasheet for the pressure rating of the transparent variant. For systems operating near the maximum pressure limit, the black PP housing version is typically specified for its higher pressure tolerance.
Threaded connections (BSP/NPT) work well for smaller systems and retrofits with existing threaded pipe. VIC clamp connections speed up installation in large projects and simplify future maintenance. Flange connections provide the strongest joint for high-pressure or permanent installations. Select based on your existing piping standard, project size, and maintenance access requirements.
Cleaning frequency depends on water quality, flow rate, and filtration grade. Monitor pressure differential across the filter and clean when the differential increases by 0.5 to 0.8 Bar above the clean baseline. With the transparent housing option, you can also visually assess debris accumulation. Typical intervals range from weekly in high-turbidity surface water to monthly in clean well water systems.
The F75TD is designed primarily for manual cleaning. For automatic backwash applications, consider filter models specifically engineered for automated flushing with motorized valves and backwash controllers. Manual T-type filters can be part of an automated system if paired with external valve assemblies and control logic, but consult the manufacturer for compatibility guidance.
