The Arkal Super Filter is the ultimate, commercial-grade solution for larger irrigation systems or any application drawing from challenging water sources heavily laden with algae, moss, and organic matter. What sets the "Super" model apart is its massive internal capacity: the disc set is twice the size of a standard Arkal filter, boasting an incredible 86.5 square inches of filtering area. This dramatic increase in surface area allows for significantly higher flow rates (up to 52 GPM) and drastically extends the amount of time required between manual cleanings. It pairs perfectly upstream of standard automated irrigation valves to safeguard your entire farm or landscape.
Built with a heavy-duty T-style body, Arkal Super Filters are rated for constant pressure up to an impressive 140 PSI, meaning they can be confidently installed directly onto your mainline. For true professional management, these filters feature dedicated ports on the top of the housing. By utilizing 1/4" female couplers to attach 1/4" liquid-filled pressure gauges (sold separately), you can instantly monitor the pressure drop across the unit. When the outlet pressure decreases significantly compared to the inlet, you know exactly when the 3D grooved discs need to be removed and rinsed.

Build your high-capacity pipe-threaded head assembly safely.
Step 1: Prep the Threads
Because this filter utilizes Pipe Threads (MPT), you must apply 3 to 4 wraps of Teflon tape to both the inlet and outlet threads to ensure a watertight seal. Do not use liquid pipe dope.
Step 2: Install the Filter
Thread the Arkal filter into your PVC manifold. Because it is rated for constant pressure, you have the flexibility to install it either upstream (before) or downstream (after) of your automated valves. Ensure the directional flow arrow points downstream toward your emitters.
Step 3: Connect Pressure Gauges (Recommended)
Use 1/4" female couplers to attach 1/4" liquid-filled pressure gauges to the ports on top of the filter. This allows you to monitor the pressure differential to know exactly when the internal discs are clogged and need cleaning.
Step 4: Routine Cleaning
When pressure drops, turn off the water supply, unscrew the main filter canister, and remove the internal disc spine. Loosen the tension nut at the top of the spine so the discs separate slightly, then rinse them thoroughly with a hose before reassembling.
Why choose the "Super" model over the standard Arkal filter?
The "Super" model features an extended canister body that houses a disc set twice the size of the standard version.
This provides a massive 86.5 square inches of filtering area, allowing it to hold significantly more debris and algae. This drastically reduces the frequency of manual cleanings, saving you serious labor on large properties.
How do the pressure gauges work?
By installing a gauge on both the inlet and outlet ports on top of the filter, you can monitor the pressure drop. When the discs become clogged with dirt, the outlet pressure will be noticeably lower than the inlet pressure, alerting you that it is time to wash the filter.
The 1/4" female couplers and gauges are sold separately.
Can I leave this filter under constant pressure?
Yes! Unlike many standard irrigation filters, the Arkal Super Filter is built and heavily reinforced to withstand constant pressure up to 140 PSI.
This means you can safely install it directly onto your mainline before your automated timer or irrigation valves, protecting the entire valve manifold from debris.
How should I prepare my Arkal Super Filter for spring watering?
As you set up your system for spring, ensure the water is turned off, unscrew the main canister, and remove the disc spine to inspect the discs for any hard winter scale, algae, or damage.
Clean them thoroughly, ensure the large O-ring inside the cap is properly seated and lubricated, and hand-tighten the canister back on. Turn the system on to verify there are no leaks before attaching your drip lines.
