How Long Will My KAS Filter Last?

KAS pre-cleaner installed on combine

The KAS Pre-Cleaner is one of those upgrades that pays for itself faster than you expect. It mounts to your machine’s air intake and spins out debris before it ever reaches your main air filter. That means less restriction, cleaner air to your engine, and way fewer filter changes. It’s a simple way to extend service intervals and keep you running.

Unlike a basic pre-screen, the KAS system uses Redekop’s patent-pending design to separate crop residue, dust, and fine debris before they clog your system. And since we’ve brought KAS to farmers and operators across North America, we’ve seen the difference it makes,  from the field to the mine.

What Kind of Filter Life Can You Expect? 

One standout example comes from a potash site in Saskatchewan. Before installing the KAS, they were changing air filters every 12 hours. After switching to the KAS? 84 hours. That’s a 7x improvement. Instead of daily downtime, it became weekly routine maintenance,  saving time, money, and headaches.

Of course, your results will vary depending on crop conditions, dust levels, and how hard the machine’s working, but that kind of leap isn’t unusual in tough environments. 

Filter Life Depends on Your Conditions 

There’s no magic number for every operator. Filter life still depends on what you’re working in,  dry vs wet crop, field vs road, clean vs dusty terrain,  but here’s what we can confidently say: if you’re running without a pre-cleaner, you’re swapping filters more often than you need to.

The KAS pre-cleaner is built for exactly these conditions, dusty harvests, long days, and high-hour machines. When you take that debris out of the equation before it ever hits the filter, you give your filter a much easier job. That adds up to fewer changes and longer protection for your engine.

Make Sure You Size It Right 

Getting the most out of the KAS comes down to proper sizing and installation. That’s why our product pages include compatibility charts and detailed install guides. Pick the correct unit for your machine, and you’ll maintain low restriction and proper air flow, both key to unlocking the filter-life benefits.

And while the KAS does reduce how often you need to change your filter, you should still monitor your machine’s air restriction gauge and follow your OEM’s recommended checks.

The Bottom Line 

When farmers and operators ask us how long their filter will last with the KAS pre-cleaner, we tell them the truth: it depends on your conditions, but the results speak for themselves. In most cases, you’re looking at multi-day or even weekly intervals instead of daily filter swaps.

That means more uptime, less money spent on replacements, and better long-term protection for your machine’s engine.
