Spring Loaded Cartridges

Description

We offer two variations of spring-loaded elements. The most common is our Spring Loaded (SL) Series of positive-fit elements, specifically designed for use in our 150 thru 162VP–4401 series stainless steel filter housings. The metal end cap construction provides added security in compressed gas systems operating under high velocity and high vibration conditions.

Final-grade coalescing elements are available encapsulated within a five-layer stainless steel structure or with a stainless steel support cage for enhanced durability and strength.

For applications involving heavy liquid and/or particulate loading, stainless steel pre-filter elements are also available.  Our coalescing microfiber elements feature integral stainless steel inner and outer cages, metal end caps for maximum durability, and a captured O-ring to ensure a positive seal. Standard element seals are Buna-N, with housing seals matched accordingly.

Alternative seal materials are available using the following ordering suffixes:

• V = Viton
• E = EPDM
• KZ = Kalrez

Example: SL38-172-70CSX3-V

Five-layer stainless steel elements are also offered in a range of micron ratings for bulk contaminant removal in demanding applications.

Spring Loaded Threaded Version (SL-TRE)

The SL-TRE Series of spring-loaded elements is engineered for high differential pressure applications and features both inner and outer stainless steel cages for maximum strength and structural stability. Reinforced support cores and an integrated spring base protect the element from dynamic pressure fluctuations, ensuring consistent filtration performance under variable operating conditions.

SL-TRE elements are specifically designed for use in our 380-383AHP, 385AHP, and 390AHP aluminum housings.

For continuous liquid removal in natural gas service, we recommend our CS Grade (all-glass fiber) coalescing spring-loaded elements. These elements deliver high efficiency while maintaining performance over extended service life without degradation.

For extreme service conditions, our EC Epoxy Coalescing Cartridges provide exceptional durability. These cartridges offer superior mechanical strength and enhanced resistance to harsh operating environments.

For the most demanding applications, we also offer coalescing elements encapsulated within a five-layer stainless steel structure. Please consult us for configuration options and detailed performance specifications.
