When To Use Wedge Wire vs. Perforated Filtration Elements

Proper straining elements protect downstream equipment and the integrity of your end-product. When it comes to selecting a sanitary strainer, what do you look for? The right strainer element can make or break the strainer’s effectiveness within the process. We’ve blogged about 6 Factors for Sizing & Selecting a Filter or Strainer, as well as 5 Questions You Need to Answer Before Selecting a Strainer. So, let's get back to basics and talk about when you should choose a wedge wire vs. perforated filtration element for your In-Line or Y-Strainer. 

In-line strainers and Y-strainers are designed to strain product, and to protect spray devices and heat exchangers from damaging particles and solids. A wide variety of strainer elements, such as wedge wire, perforated, mesh overlay and filter bags, allow you to achieve the desired final product and comply with governing agencies relevant to your process. Which one should you choose?

When to choose wedge wire?

Wedge wire elements work great when you need finer straining capabilities for round or square particles without the use of a filter or mesh overlay. Pressure drop is also an important consideration as it refers to a decrease in fluid pressure across a piping component, such as a filter or strainer. Wedge wire elements are ideal for highly viscous applications where the pressure drop might be higher.

When to choose perforated?

Perforated filtration elements are designed for sanitary applications where 3-A certification is required and when larger particles and solids must be captured to prevent damage to downstream equipment. Perforated elements are also ideal when seeking to strain finer particles by incorporating filter media or mesh overlays.

Selecting filtration elements that are properly designed for your application can be tricky. Choosing the wrong one can wreak havoc on downstream equipment if it does not capture the right amount of solids.
