Why Sprayer Strainers Are Your Best Defense

Think of sprayer filtration as a series of gates, each one finer than the last. A single filter is a single point of failure. A layered system, however, ensures that debris is caught systematically, from large particles at the tank to microscopic ones right at the nozzle.

This system starts with a coarse filter in the tank opening, followed by a suction strainer before the pump, an in-line strainer after the pump, and finally, small tip strainers at each nozzle. Each stage protects the next. The suction strainer saves your pump from damage, the line strainer protects your boom components, and the tip strainers provide the final defense for the delicate nozzle orifice.

Ignoring this layered approach is the most common mistake I see. People either rely on a single filter or skip one entirely, usually the suction strainer. This inevitably leads to clogs, pump damage, and inconsistent application, which can mean patchy weed control or uneven fertilizer coverage.

TeeJet AA122 Line Strainer: The All-Rounder

If you only have one in-line strainer on your sprayer, it’s probably a version of this one. The TeeJet AA122 is the workhorse of post-pump filtration. It’s installed between your pump and the spray boom, acting as the primary defense for all your nozzles.

Its strength lies in its simplicity and versatility. The clear bowl lets you see when it’s getting dirty, and the unscrew-and-rinse cleaning process is straightforward. You can get screens for it in various mesh sizes, but the 50 mesh (blue) or 80 mesh (red) are the most common and useful for general-purpose spraying. A 50 mesh is perfect for most herbicides and liquid fertilizers, while the 80 mesh offers finer filtration for products that are more prone to clogging.

This strainer isn’t fancy, but it’s incredibly reliable. Its heavy-duty polypropylene body handles most farm chemicals without issue. For a hobby farmer with a boom sprayer for a few acres of pasture or a large garden, this is a non-negotiable component that provides excellent protection for a very reasonable cost.

Hypro 3350 Suction Strainer: First Line of Defense

The suction strainer is the unsung hero of your spray system. Placed on the intake hose between the tank and the pump, its job is simple: protect the pump. Your pump has tight tolerances, and even small debris like a stray leaf fragment or a clump of undissolved powder can cause serious damage to its diaphragms or rollers.

The Hypro 3350 is a fantastic example of a robust suction strainer. It has a large surface area, which means it can catch a lot of gunk before it starts to restrict flow and starve your pump. Starving the pump, a condition called cavitation, can destroy it in minutes. This strainer prevents that.

Don’t ever pull water from a pond, creek, or even a questionable storage tank without a suction strainer in place. It’s the difference between a pump that lasts for years and one that dies mid-season. It’s your first and most important line of defense.

Banjo T-Line Strainer: For Easiest Clean-Outs

Cleaning strainers is a necessary chore, but it doesn’t have to be a messy one. This is where the Banjo T-Line Strainer shines. Its brilliant design places the filter bowl on the bottom of a "T" fitting, allowing you to shut off the flow, unscrew the bowl, and clean the screen without disconnecting any hoses.

This might sound like a small detail, but it’s a huge quality-of-life improvement. On a conventional in-line strainer, you often have to wrestle with stiff hoses, leading to spills and frustration. With the Banjo T-Strainer, you can check and clean your filter in under a minute, making you far more likely to do it regularly.

This is the strainer I recommend to anyone building their own sprayer or upgrading an existing one. The time and hassle it saves are well worth the slightly higher initial cost. It’s a perfect example of smart design making a recurring task simple and clean.

Greenleaf Combo-Jet: Integrated Nozzle Protection

Even with perfect filtration upstream, tiny particles can still make their way to the nozzles. This is especially true if you have older hoses that might be degrading internally. The Greenleaf Combo-Jet system solves this by integrating the strainer directly into the nozzle cap assembly.

This design combines the nozzle body, cap, gasket, and strainer into a single, easy-to-handle unit. The strainer is a cylindrical screen that sits directly behind the spray tip, providing last-chance protection right where it matters most. It’s the final gatekeeper, ensuring that anything reaching the tiny orifice of your spray tip is clean fluid.

The convenience is a major benefit. When you do get a clog, you can quickly twist off the cap, rinse the small screen and tip, and be back to spraying in seconds. For anyone tired of fumbling with tiny, separate strainer screens that always seem to get lost, this integrated system is a game-changer.

Arag 324 In-Line Filter: High-Flow Capacity

For those of us with slightly larger setups—maybe a 50-gallon tank and a pump that moves more than 5 gallons per minute—a standard line strainer can become a bottleneck. The Arag 324 is a high-capacity filter designed to handle higher flow rates without causing pressure drops.

The key is its massive filter screen. A larger surface area means it can trap more debris before it needs cleaning and allows liquid to pass through with less restriction. This is crucial for maintaining consistent pressure across your entire boom.

While it might be overkill for a small ATV spot sprayer, it’s the perfect choice for a 3-point hitch sprayer covering several acres. If you find yourself cleaning your standard line strainer multiple times per tank, upgrading to a high-capacity model like the Arag will significantly reduce your downtime.

Fimco Tip Strainers: Affordable Last-Chance Filters

Sometimes, the simplest solution is the best. Fimco tip strainers are small, inexpensive, drop-in filters that sit inside the nozzle body, right behind the spray tip. They are the most basic form of last-chance filtration you can get.

They aren’t fancy. They are just a small mesh screen, often color-coded to match the mesh size of your main line strainer. The rule of thumb is simple: your tip strainer mesh should be equal to or finer than your main line strainer mesh. For example, if you use a 50-mesh line strainer, use 50-mesh or 100-mesh tip strainers.

Because they are so cheap, you can keep a dozen on hand. If one gets hopelessly clogged with a stubborn chemical residue, you don’t have to waste time scrubbing it—just toss it and drop in a new one. They are an essential, low-cost final guard against frustrating tip clogs.

Strainer Maintenance for Clog-Free Spraying

The best strainer in the world is useless if it’s already full of junk. Consistent maintenance is the secret to clog-free spraying. It doesn’t take long, but it needs to become a habit.

Make it a rule to check your strainers at the end of every spray day. When you’re rinsing your tank, take a few extra minutes to open up your suction and line strainers. A quick rinse with a hose is usually all it takes. For stubborn residue, especially from wettable powders, an old toothbrush is your best friend.

Pay attention to what you find. If your line strainer is always full of large debris, it means your tank-fill or suction strainer isn’t doing its job. If your nozzle screens are clogging but the line strainer is clean, you might have residue breaking loose from inside your hoses. Your strainers don’t just prevent clogs; they tell you a story about the health of your entire spray system.

Ultimately, a reliable sprayer depends on a smart, layered filtration system, not just a single part. By matching the right strainers to your setup—from the suction hose to the nozzle tip—you trade a few minutes of maintenance for hours of saved time in the field. Stop fighting clogs and start spraying with confidence.

Frequently Asked Questions (FAQs)

What is a sprayer strainer on an agricultural spray rig?

A sprayer strainer is an inline filtration device that captures dirt, rust, and chemical flakes before debris reaches and clogs the spray nozzles. Placed between the tank, pump, and boom lines, sprayer strainers use a cylindrical mesh screen housed inside a bowl. Mesh materials typically feature stainless steel or polypropylene. Installing one prevents nozzle abrasion, maintains uniform spray patterns, and protects expensive pressure pumps from grit scoring.

What does mesh size mean on a sprayer strainer?

Mesh size on a sprayer strainer measures the number of openings per linear inch of the screen material. Higher mesh numbers indicate smaller holes that catch finer particles, while lower numbers represent coarser filtration. For instance, a 50-mesh screen has larger openings suited for viscous liquid fertilizers, whereas a 100-mesh screen catches the micro-sediment required for small nozzle orifices like 01 and 02 tips. Choosing the right mesh prevents line restriction and pump cavitation.

How do I clean a clogged sprayer strainer without damaging the screen?

Clean a clogged sprayer strainer by shutting off the tank valve, unscrewing the housing bowl, and scrubbing the wire cylinder with a soft-bristle nylon brush. Rinse the mesh thoroughly using clean tap water or a bucket wash rather than high-pressure power washers, which can tear delicate wire weaves. Avoid metal picks or knives because scratching the mesh creates larger holes that let debris bypass directly to the nozzle tips. Inspect the sealing O-ring before hand-tightening the bowl back onto the body.

How often should you inspect sprayer strainers during heavy spraying season?

Farmers and applicators should inspect sprayer strainers at the start of every operating day or whenever switching between different tank-mix chemicals. Daily visual checks take under two minutes and reveal chemical curdling, sediment buildup, or torn screens early. If you apply dry flowables or wettable powders, check the screens after every two or three loads because those formulations settle quickly. Always flush the system with clean water at the end of the day to stop residues from hardening inside the screen basket.

Is a 50 mesh or 100 mesh sprayer strainer better for spraying herbicides?

Selecting between a 50 mesh or 100 mesh sprayer strainer depends directly on nozzle flow ratings and herbicide formulation viscosity. Standard 50-mesh strainers work best for medium-to-large nozzle tips (03 to 08 sizes) and heavy suspension herbicides that would otherwise plug tighter screens. In contrast, 100-mesh strainers are better for fine herbicide sprays using 01 or 015 tips to prevent tiny orifices from clogging. Check your nozzle manufacturer chart to match mesh size to specific tip orifices.

How much does a replacement sprayer strainer cost for farm sprayers?

Replacement sprayer strainers typically cost between $15 and $85 for standard inline poly units, while replacement internal mesh screens cost $5 to $20. Basic 1/2-inch to 3/4-inch polypropylene line strainers sit at the lower end around $15 to $30. Heavy-duty 2-inch to 3-inch high-capacity suction strainers or stainless steel assemblies range from $60 to over $150. Replacing an intact housing’s internal screen alone saves money and restores full flow capacity in minutes.

Why are spray nozzles still clogging after installing a sprayer strainer?

Spray nozzles continue clogging after strainer installation when the filter mesh is too coarse, the screen is torn, or debris forms downstream inside hoses. A common problem occurs when chemical tank mixes react and precipitate after passing through the main line filter, creating globs before the tip. Loose hose degradation also sheds rubber flakes directly into nozzle bodies. Add tip strainers (50 to 100 mesh) right behind each nozzle cap and verify your main suction and pressure screens have no holes or seated gaskets out of position.

Is a multi-stage sprayer strainer system worth the extra cost for broadcast spraying?

Installing a multi-stage sprayer strainer system is well worth the extra investment because it eliminates costly downtime and prevents uneven application rates across fields. Multi-stage filtration utilizes a coarse 30-mesh suction strainer on the intake side, a 50-mesh pressure line strainer, and individual 100-mesh nozzle tip filters. This graduated design traps larger twigs and insolubles first without cutting pressure, while protecting expensive pump seals and precision nozzles. Avoiding a single clogged-nozzle re-spray over fifty acres typically pays for all supplemental strainers immediately.
