It’s often the best way to justify the investment to a procurement team—showing them exactly why Titanium wins in the long run.

Here is a comparison table and a deeper dive into the "Titanium Advantage" to round out your product page.

While Stainless 316L is a standard in many industries, it often fails in high-chloride or high-heat acidic environments where Titanium Grade 2 thrives.

The secret to Falcon’s Titanium strainers is the Titanium Dioxide film. If the surface of the basket is scratched or abraded by debris during the filtration process, the metal reacts instantly with any trace of moisture or oxygen to rebuild its protective layer. This makes it virtually immune to the erosion-corrosion that typically destroys steel baskets in high-velocity mining or oil and gas applications

Precision Engineering for Flow Efficiency 

Our basket geometry is optimized to:

1. Reduce Pressure Drop: Larger screen surface area means less energy required for pumps.

2. High Dirt-Holding Capacity: Longer intervals between cleaning cycles.

3. Structural Integrity: Heavy-duty basket handles and reinforced mesh prevent "blow-outs" under high pressures

Here is a professional, high-impact description tailored for your website. It emphasizes both the technical superiority of the material and your company’s long-standing expertise.
