What is a Y-Type Filter (Water Filter)?
A Y-type filter (water filter) is a pipeline-style coarse/medium filtration device with a "Y" shaped structure. Its core function is to trap solid impurities in water, protecting subsequent pipelines, valves, or precision equipment from clogging or wear.
1.Core Definition & Structure
Features a "Y" shaped appearance, installed in water pipelines to allow fluid to pass through the filter chamber following its natural flow direction.
The key component is a built-in filter screen (commonly made of stainless steel with a pore size of 10-100 mesh). The screen traps rust, sand, and impurity particles in water, while clean water flows out through the screen.
Equipped with a sewage discharge port at the bottom, which can be opened regularly to drain trapped impurities without disassembling the entire device, enabling convenient maintenance.
2.Core Functions & Applicable Scenarios
Mainly serves as "coarse filtration" to remove visible solid particles from water, protecting downstream equipment such as water pumps, flow meters, and precision filters.
Suitable for scenarios including industrial cooling water systems, tap water supply pipelines, HVAC pipelines, and pre-filtration in sewage treatment. It is particularly ideal for water systems with low requirements for impurity interception (no need for high-precision filtration).
3.Key Differences from PTFE Membrane Precision Filters
Filtration Precision: Y-type filters are mostly for coarse filtration (10-100 mesh, approximately 150-120μm), while PTFE membrane precision filters offer precision filtration (0.05μm-10μm).
Filter Medium: Y-type filters use metal screens; PTFE membrane precision filters adopt PTFE membranes to physically trap fine impurities through micro-pores.
Purpose: Y-type filters focus on "protecting pipeline equipment," while PTFE membrane precision filters prioritize "improving fluid purity" (e.g., sterilization, colloid removal).
