KIMAIR K Series Oil-air Separator Elements

The KIMAIR K Series oil separator element (referred to as "separator element") is a core consumable component of screw air compressors, professionally installed inside the compressor's oil separator tank. Its core function is to efficiently separate the oil-air mixture discharged from the airend, reducing the oil content in the compressed air to an extremely low level (as low as ≤3 ppm), while ensuring that the separated lubricating oil returns cleanly to the oil circuit for reuse. As a key consumable requiring regular replacement, its performance directly affects compressed air quality, equipment energy consumption, and operating costs.

Customer Frequently Asked Questions (FAQ)

Q1: How to determine when the separator element needs replacement?

A: Three main signals: ① system differential pressure reaches 0.8-1.0 bar (refer to equipment manual); ② outlet air oil content exceeds standard; ③ lubricating oil consumption abnormally increases (more than 15% above normal).

Q2: Why should cheap alternative separator elements not be used?

A: Cheap separator elements have low separation efficiency and high differential pressure, leading to: ① contaminated compressed air damaging downstream equipment; ② abnormal lubricating oil consumption increasing costs; ③ increased system differential pressure raising energy consumption; ④ separation failure potentially causing safety risks.

Q3: What is the correct procedure for replacing the separator element?

A: Professional procedure includes: ① stop and relieve pressure; ② replace the "maintenance kit" (separator element + lubricating oil + oil filter); ③ clean sealing surfaces; ④ check the new filter element seals; ⑤ correct installation and pre-lubrication; ⑥ start and check differential pressure.

Q4: How do harsh conditions affect service life?

A: High temperature (>40°C), high humidity, high dust, and poor lubricating oil quality will significantly shorten service life. It is recommended to shorten the replacement interval by 20-30% in harsh environments and strengthen equipment maintenance.
