Product Overview
For large‑capacity water‑treatment projects, traditional small‑size filter cartridges bring huge installation quantity and heavy replacement workload. L‑Series High Flow Filter Cartridge solves this pain point by adopting 6‑inch large‑diameter pleated structure, which can achieve high throughput with much fewer elements. It is installed inside Water Filter Element matching high‑flow filter housing, widely used for reverse‑osmosis pre‑treatment, power‑plant condensate filtration, petrochemical process water and food‑beverage mass‑production water system. Integrated injection‑molded PP end‑cap and hot‑melting welding eliminate glue‑related risk of medium contamination.

Project‑oriented Application Cases
The biggest advantage of L‑series high‑flow cartridge is reducing total investment and later‑stage maintenance work for large‑flow stations. In seawater desalination pre‑treatment projects, dozens of traditional 2.5‑inch small cartridges can be replaced by just a small number of L‑series cartridges, which shortens filter‑housing size and cuts element‑replacement labor hours. Power‑plant condensate‑water loop also chooses this series, handling circulating water containing fine rust particles. Petrochemical plant process‑water and large‑scale beverage factory raw‑water purification are also typical application cases. High Flow Filter Cartridge product family includes K/M/R series for different project requirements.
Core Product Advantages
Built‑in integrated lifting‑handle makes on‑site cartridge pulling‑out fast and convenient without auxiliary tools. Multi‑layer gradient‑pleated media combines surface‑filtration and deep‑filtration effect to raise dirt‑holding capacity. All welding points adopt hot‑melting technique without chemical adhesive, avoiding medium pollution risk. Special sealed‑interface design lowers bypass‑leakage probability. Large‑diameter pleated layout enlarges effective filtering area and keeps pressure‑drop at relatively low level under high‑flow working status. Oil Filtration Machine series also apply gradient‑media concept for solid‑liquid separation.
Manufacturer & Factory Strength
Our factory has complete large‑flow‑cartridge production line. Each finished L‑series cartridge undergoes bubble‑point integrity test and pressure‑resistance inspection before delivery. We accumulate rich experience cooperating with seawater‑desalination, thermal‑power‑plant and petrochemical EPC contractors. We can provide free specification consulting according to project flow‑rate, raw‑water quality and housing dimension. replacement imported filter element workshop shares the same set of pressure‑test equipment.
FAQ
Q1：What is the main difference between L‑series and K‑series high‑flow cartridge?
A1：They differ in internal support‑cage structure and handle style. L‑series mainly targets heavy‑duty RO pre‑treatment and condensate‑water projects; K‑series is more fit for drinking‑water and waste‑water working‑conditions.
Q2：Does L‑series cartridge fit old‑brand third‑party high‑flow housings?
A2：We support customized connection‑end dimensions. Please offer housing drawing or original sample size for us to verify interchange possibility.
Q3：Can glass‑fiber media L‑series be used for drinking‑water contact scenario?
A3：Glass‑fiber version is suggested for industrial process‑water. For drinking‑water project, we recommend pure poly‑propylene media solution.
Q4：How to judge when to replace L‑series high‑flow filter cartridge?
A4：Replace cartridges when system differential‑pressure reaches 2.5 Bar @20℃, or when outlet‑water turbidity rises abnormally.
Q5：Can you provide bulk‑order delivery for EPC project schedule?
A5：We support project‑oriented bulk‑supply and can adjust production‑schedule according to customer project‑timeline. Please send project‑related parameters for quotation.
