The Arkal 2" Dual Lite Filter is the ultimate commercial-grade solution for agricultural operations and expansive landscapes that draw from challenging surface water sources. If your system relies on a pond, creek, canal, or reservoir, standard mesh screens will quickly blind over with organic matter and algae. The Dual Lite combats this using Arkal's renowned 3D stacked-disc technology. With an absolutely massive 147 square inches of filtering area—nearly twice as large as the standard 1 1/2" model—this filter effortlessly handles flow rates up to 110 GPM while drastically extending the time between manual cleanings. Install it seamlessly upstream of your irrigation valves to safeguard your entire farm.
Beyond its incredible capacity, the Dual Lite is engineered for superior user convenience. Instead of struggling to unscrew a massive, tightly bound threaded canister, the housing is secured with a heavy-duty plastic clasp that opens instantly to grant access to the internal discs. Additionally, this filter offers a highly unique, reversible plumbing design: the outlet can be configured on the side (standard) or switched to the top of the filter housing, giving you the flexibility to build your 2" PVC manifold exactly how you want it. Rated for constant pressure up to 116 PSI, the Dual Lite provides industrial-strength filtration you can rely on.

Build your high-capacity pipe-threaded head assembly safely.
Step 1: Prep the Threads
Because this filter utilizes 2" Pipe Threads (MPT), you must apply several wraps of Teflon tape to both the inlet and outlet threads to ensure a watertight seal. Do not use liquid pipe dope.
Step 2: Choose Outlet Configuration
Determine whether your PVC manifold design requires a side outlet (standard) or a top outlet. Configure the cap and outlet port accordingly before installation.
Step 3: Install the Filter
Thread the Arkal Dual Lite filter into your heavy-duty PVC manifold. Because it is rated for constant pressure up to 116 PSI, you have the flexibility to install it either upstream (before) or downstream (after) of your automated valves.
Step 4: Routine Cleaning
When you notice a drop in pressure, turn off the water supply. Unhook the large plastic clasp, pull the housing cover off, and remove the internal disc spine. Loosen the tension nut so the discs separate slightly, then aggressively rinse them with a hose to remove all algae and sediment.
Why choose a disc filter over a screen filter for ponds?
While screen filters act as a flat 2D barrier, a disc filter uses a stack of grooved plastic rings to create a deep, 3D filtration pathway.
This "depth filtration" is incredibly effective at trapping organic matter like algae, moss, and slime that would immediately plaster over and blind a flat stainless steel screen. Disc filters are absolutely essential for ponds, creeks, and dirty surface water.
How do I open the filter to clean it?
Unlike traditional filters that require you to muscle off a massive, tightly threaded canister, the Dual Lite utilizes a quick-access plastic clasp.
Simply relieve the system pressure, unhook the clasp, and pull the cover away to instantly access the disc spine. No tools or strap wrenches required.
Can I change the outlet from the side to the top?
Yes, one of the major advantages of the Dual Lite filter is its reversible plumbing design.
You can easily switch the outlet port from its standard side-exit configuration to a top-exit configuration, granting you immense flexibility when building tight or complex PVC manifolds.
How should I prepare my Arkal filter for spring watering?
As you set up your system for spring, ensure the water is turned off, open the plastic clasp, and remove the disc spine to thoroughly inspect the discs for any hard winter scale, dried algae, or damage.
Clean them thoroughly, ensure the large O-ring inside the housing is properly seated and lubricated, and secure the clasp. Turn the system on to verify there are no leaks before pressuring your mainlines.
