ZS1093258

ZS1093258 is a high-efficiency built-in air-oil separator designed specifically for industrial large screw air compressors. As an authentic aftermarket core maintenance part of CompAir, it adopts advanced coalescing filtration technology. It is engineered to deliver compressed air of extremely high purity for industrial gas sources, while minimizing lubricating oil loss and protecting the downstream system of the equipment.

Working Principle: Coalescence Separation Technology (Coalescence Principle)

During the operation of the screw air compressor, lubricating oil is used for sealing, lubricating and cooling the rotors, which results in a large number of suspended mist-like oil droplets in the discharged compressed air.

Interception and Coalescence: As the mixed gas passes through the ultra-fine glass fiber layer of ZS1093258, tiny oil mist droplets are intercepted by the filter medium and gradually coalesce into large oil droplets.

Oil Return Circulation: Under the effect of gravity, the coalesced large oil droplets settle to the bottom of the separation element and are drawn back to the main circulation system of the compressor head through the oil return pipe of the air compressor under differential pressure for recycling.

Core Product Advantages

•  Ultra-low residual oil content (

•  Ultra-low initial pressure drop (≤ 0.1–0.25 bar): The optimized aerodynamic structure creates minimal resistance to gas flow. Every 0.1 bar reduction in pressure drop directly cuts the motor energy consumption of the entire air compressor by approximately 1%.

•  Excellent service life: The standard maintenance interval reaches up to 4000 operating hours (subject to the working environment, inlet dust concentration, and the quality of oil filters and lubricating oil).

• Static grounding protection: Conductive static gaskets are fitted on all filter element flanges to prevent static electricity generated by friction from high-speed airflow through the filter element, eliminating the risk of combustion and explosion inside the oil-gas tank for reliable safety.
