PTFE, PVDF & PPL Baffle Strainers

Non-Alloy Tee Strainers for Aggressive Liquids

Our PTFE, PVDF and PPL baffle strainers provide efficient, reliable filtration for liquids that are aggressive to most alloys and for use in PTFE, PVDF or PPL piping systems. You can install a baffle insert into an existing tee fitting or order a complete tee strainer assembly.

Baffle Strainers vs. Start-Up Strainers

Baffle Strainers are designed for continuous filtration. They remain permanently in the pipeline and protect equipment on an ongoing basis. The internal baffles or vanes direct fluid flow to improve particle capture and reduce turbulence.

Start-Up Strainers are temporary devices used only during the initial commissioning of a pipeline. They capture construction debris, rust and scale, then are removed once the system is clean and stable.

When to Use Each Type

Baffle strainers excel in continuous-duty applications found in petrochemical, refining, chemical processing and wastewater treatment. The baffle design enhances particle retention while helping to minimize pressure drop.

Start-up strainers are ideal for pipeline commissioning in construction, pharmaceutical and food-processing projects. They are quick to install and remove, providing essential temporary protection.

Choose a baffle strainer when you need long-term continuous filtration. Choose a start-up strainer when you only need temporary protection during system start-up.
