GL14 high-low connector basket filter is a high-efficiency filtration device specifically engineered for specialized piping layouts. Its distinguishing feature is the asymmetric positioning of the inlet and outlet nozzles (high-inlet/low-outlet or vice versa), which allows for direct connection to staggered pipeline systems, simplifying configurations and saving valuable installation space. The unit consists of a housing, a large-capacity stainless steel basket, a sealing cover, and a blowdown device. Primarily installed upstream of pumps, heat exchangers, or instruments, it continuously intercepts solid impurities. Due to its basket structure, which provides a filtration area significantly larger than the pipe cross-section, this series offers advantages such as low pressure drop, high dirt-holding capacity, and extended service intervals. It is an ideal pre-treatment device for ensuring equipment safety in petroleum, chemical, energy, and municipal water systems.

1.Unique high-low connector layout:The asymmetric nozzle height design permits direct integration with offset pipelines, significantly reducing the need for elbows and fittings while optimizing network routing in confined spaces.
2.High efficiency and low pressure drop:The effective filtration area of the internal basket is typically 3 to 5 times the flow cross-section, minimizing fluid resistance. This ensures an extremely low initial pressure drop even at high flow velocities, promoting energy efficiency.
3.Large dirt-holding capacity:The deep-bucket basket structure provides excellent space for debris accumulation, capturing large volumes of weld slag, rust, and particulates. This extends the operational cycle between cleanings and reduces maintenance frequency.
4.Top-entry rapid opening structure:Utilizing a bolted or quick-open top cover design, maintenance only requires loosening the fasteners to extract the basket vertically. This eliminates the need to remove the filter from the line, enabling rapid online cleaning.
5.Superior sealing reliability:Combined with precision-machined flange faces and high-performance gaskets (e.g., flexible graphite or PTFE), it ensures bubble-tight integrity under high-pressure fluctuations or thermal expansion.
6.Wide material and specification range:Housings are available in cast steel, stainless steel (304/316L), and alloy steels. The basket mesh size can be flexibly configured to meet various process requirements, from coarse interception to fine filtration.
7.Erosion resistance and structural stability:The optimized internal cavity flattens the flow to cushion direct impact on the basket. A robust support structure ensures the basket remains undeformed under high differential pressures.
8.Low O&M cost and long life:The simple design features no moving parts besides the screen. Key components are treated with anti-corrosion or hardening processes, offering excellent wear resistance and long-term economic benefits.
