1623051600 Atlas Copco 4-Stage Mist Separator
The 1623051600 Atlas Copco oil water separator, also known as an OEM oil mist filter element, is an exclusive core replacement part for Atlas Copco screw air compressors. First of all, it targets high-pressure mixed oil-air exhaust from compressor hosts. In addition, it efficiently separates hot pressurized oil-air mixtures into dry clean compressed air and recyclable lubricating oil. Meanwhile, it guarantees purified air supply for downstream pneumatic equipment and cuts long-term lubricant consumption costs. Moreover, it effectively protects internal compressor host parts from abrasive wear. Notably, its entire operation relies on multi-stage physical separation without chemical reactions. Besides, it fully depends on mechanical airflow force and specialized filter media properties to finish high-precision purification as detailed below.
I. 1623051600 Core Structure
First of all, the 1623051600 adopts a spin-on install design that perfectly matches Atlas Copco compressor oil tank mounting dimensions. Furthermore, its key assemblies include ultra-fine glass fiber composite filter media, reinforced metal support mesh, upper & lower sealed end caps, central air outlet channel and bottom lubricant return port. Specifically, the imported ultra-fine glass fiber media features strong oleophilic property, uniform tiny pores and large oil holding capacity to trap micro oil mist particles efficiently. Additionally, the rigid metal mesh prevents filter media collapse under high-speed high-pressure airflow impact. Meanwhile, sealed end caps avoid unseparated raw gas leakage before purification. Besides, the bottom return port connects the circulating oil recovery pipeline for continuous lubricant reuse. In particular, this model uses a 3-layer composite media structure: pre-filter coarse layer, fine purification layer and oil coalescence layer.
1. Pre-Buffering & Gravity Sedimentation
When the Atlas Copco screw host runs stably, it injects lubricant into compression cavities for lubrication, sealing and cooling protection. Subsequently, compressed hot high-pressure oil-air mixtures (80-120℃ temperature, 0.7-1.0MPa working pressure) flow into the oil tank through exhaust check valves. Since the 1623051600 separator installs inside the oil tank, the mixed gas first finishes rapid expansion deceleration in the large tank space. For this reason, airflow speed drops sharply to lay a foundation for follow-up precise separation. Meanwhile, relying on density difference between oil and air, large oil droplets over 10μm sink to the tank bottom naturally via gravity. Finally, this pre-step removes about 90% raw liquid lubricant effectively.
After pre-sedimentation, residual mixed gas with tiny floating oil mist flows forward under airflow push. Then it moves along the inner wall of the 1623051600 separator in tangential direction to form strong rotating airflow and powerful centrifugal force. Furthermore, heavy oil mist particles are thrown to the inner wall surface due to centrifugal effect. Next, tiny oil droplets collide and coalesce into larger heavy droplets, which slide down to the oil tank bottom along the wall. In turn, this coarse centrifugal step removes another 5% floating oil mist, leaving only submicron oil particles below 1μm for deep filtration.
3. Ultra-Fine Fiber Deep Filtration
Subsequently, pre-separated mixed gas flows upward into the core ultra-fine glass fiber media area of the 1623051600 separator. Notably, the dense fiber media acts as a professional micro oil mist catching net for industrial compressors. When oil-contained airflow penetrates the media, three physical mechanisms realize ultimate precision separation clearly. First, direct interception traps oil particles larger than media pores on the surface directly. Second, diffusion adsorption catches submicron mist via irregular Brownian motion deviation and fiber adhesion. Third, coalescence effect gathers adsorbed mist into heavy large droplets by strong oleophilic property. Eventually, this core step controls residual oil content in output air below 3ppm strictly to meet high-clean pneumatic standards.
4. Air Supply & Lubricant Recovery
Once deep fiber filtration finishes completely, purified dry compressed air penetrates the media into the central outlet channel. After that, it discharges from the top oil tank port to post-coolers for temperature reduction before supplying downstream industrial pneumatic machinery. Meanwhile, heavy coalesced oil droplets on media surfaces slide down to the separator bottom via gravity naturally. Finally, they enter the circulating oil pipeline through the bottom return port, pass small oil return filters and flow back to the compressor host directly. Thus, it realizes continuous lubricant recycling to cut equipment operation and maintenance costs obviously.
III. 1623051600 Matching Supporting Parts
The high-efficiency long-life operation of the 1623051600 oil separator needs perfect coordination with other Atlas Copco compressor accessories. First, the minimum pressure maintaining valve keeps stable 0.4MPa internal tank pressure. Hence, it provides necessary pressure difference power for oil-air separation and lubricant recovery, also preventing air backflow during equipment unloading. Second, the anti-backflow oil return check valve installs on circulating oil pipelines. It avoids high-pressure air and lubricant backflow damaging filter media or causing difficult startup after host shutdown. Third, the intelligent temperature control thermostat adjusts real-time lubricant working temperature. It keeps lubricant in optimal viscosity state and prevents excessive tiny mist caused by overheating. In turn, it indirectly improves the overall mist separation efficiency of the 1623051600 filter element effectively.
IV. 1623051600 Core Principle Summary
In short, the 1623051600 OEM oil mist separator applies a mature multi-stage physical purification mode: expansion deceleration → centrifugal impact → ultra-fine fiber deep filtration. Meanwhile, it leverages oil-air density difference, powerful centrifugal force and fiber oleophilic adsorption characteristics fully. As a result, it thoroughly separates exhaust mixed gas from screw compressor hosts to achieve dual goals: dry clean compressed air output and continuous lubricant circulating recovery. Its biggest advantage lies in exclusive customization for Atlas Copco compressor working parameters. Moreover, the 3-layer composite media design balances ultra-high 3ppm separation precision, large oil holding capacity and long service life perfectly. Unlike universal generic separators, its external size and internal media specs fully fit Atlas Copco original equipment demands. Therefore, it guarantees 100% matching separation efficiency and stable long-term operation of industrial screw air compressors.
