Overview

BOLEFIL L-strainers are built on the same durable foundation and in-line cleanability as our Y-strainers, but feature a 90° mounting orientation, offering flexibility for system layouts where space or piping direction requires an angled installation.

The series includes both standard and high-capacity models to accommodate a wide range of process requirements. High-capacity L-strainers are designed to support increased flow rates, handle more viscous fluids, and minimize pressure drop, ensuring efficient operation within data center liquid cooling systems.

L-strainers are suitable for integration into Coolant Distribution Units (CDUs) and other process systems where reliable particulate filtration is essential. Their bi-directional flow capability allows effective filtration while simplifying cleaning and maintenance without pipeline removal.

A range of customization options is available to tailor each strainer to specific process needs. Customers can choose from different strainer sizes and mesh types, select drain ports ranging from 0.75” to 6.0” for sampling or draining, and opt for dual sight glasses in tempered glass or acrylic.
