1616719480=1616719490 | ATLAS COPCO OIS K-38 AIR END

The geniune Atlas Copco OIS K-38 air end, part number 1616719480 (=1616719490), acts as the core compression head for Atlas Copco mobile air compressors.

Product Introduction

Every mobile screw compressor relies on its air end to convert atmospheric air into high-pressure compressed air for construction, mining, quarrying, pipeline maintenance and heavy-duty onsite pneumatic operations. This air end is brand new genuine product, sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd., with manufacturing origin in Belgium. Our supplier, Sichuan Sekes Mechanical And Electrical Technology Co., Ltd., delivers this authentic Atlas Copco compression element with complete traceability and full product documentation for every shipment.

Atlas Copco designs the OIS K-38 air end to withstand harsh, variable site conditions. Mobile air compressors often operate in dusty construction zones, high-altitude mining sites and humid coastal environments. This air end maintains stable airflow output and keeps consistent working pressure even under continuous heavy load. Many site operators choose this air end replacement to restore their mobile compressor’s original factory performance instead of purchasing an entire new compressor unit. It eliminates costly full-machine replacement downtime and protects your existing investment in Atlas Copco portable compressor equipment.

This genuine Atlas Copco OIS K-38 air end undergoes strict factory testing before release. Quality inspectors run full performance, pressure, leakage and durability tests at the Belgium production facility. Every unit meets Atlas Copco’s global technical standards for mobile compressor core components. When you install this air end, you regain the same reliability, fuel efficiency and output capacity your compressor had at the original factory delivery.

Working Principle

The OIS K-38 belongs to the rotary screw air end family, the proven compression technology behind Atlas Copco mobile diesel air compressors. It uses precision-machined male and female interlocking screw rotors housed inside a heavy-duty cast casing. When the compressor engine transfers rotational power to the air end, the male rotor drives the female rotor to spin in opposite directions.

The rotating rotors create expanding cavities at the air inlet side. Atmospheric air flows freely into these cavities. As rotors continue turning, the air-filled cavities move toward the discharge port and gradually shrink in internal volume. Volume reduction directly compresses the trapped air and raises air pressure. Lubricating oil injects into the compression chamber during this process. The oil seals tiny gaps between rotors and housing to reduce air backflow, cools the compressed air, and lubricates rotor bearings to lower friction and wear.

After compression completes, high-pressure air flows out from the air end outlet and enters the compressor’s air-oil separation system. The whole compression cycle runs continuously while the mobile compressor stays in operation. The precision rotor profile of OIS K-38 minimizes energy loss and delivers stable compressed air flow, which directly cuts fuel consumption for your mobile compressor during long onsite working shifts.

When to Replace

You must inspect your mobile compressor element regularly according to Atlas Copco’s official maintenance guidelines. Normal service life for the OIS K-38 air end reaches 50,000 to 60,000 operating hours under standard operating conditions with proper lubrication and filter maintenance. You schedule planned air end replacement before you hit this hour mark to avoid unexpected onsite breakdown.

Watch for these warning signs that signal immediate air end replacement requirement:

1. Unusual loud grinding, knocking or metal friction noise from the compressor main housing during operation.
2. Sharp drop in compressed air flow or working pressure while engine runs at normal speed.
3. Excessive oil consumption and heavy oil carryover in the compressed air outlet.
4. Continuous high discharge temperature that standard cooling maintenance cannot fix.
5. Frequent internal rotor seal failure or repeated bearing alarms from compressor control panel.

Delaying air end replacement creates serious risks. A worn air end can lock up suddenly during operation and cause catastrophic damage to your mobile compressor engine and drive system. For construction and mining projects with tight deadlines, unplanned shutdown leads to expensive project delays and extra rental costs for backup air equipment. We recommend you keep a genuine OIS K-38 air end on hand as a spare unit for critical heavy-duty mobile compressor fleets.

Key Advantages

1. Original factory precision manufacturing

Atlas Copco manufactures this OIS K-38 air end in Belgium with ultra-tight machining tolerances for rotors and casing. The perfectly matched rotor profile delivers maximum volumetric efficiency and keeps energy consumption at factory designed levels.

2. Long service life for mobile onsite working

This air end withstands frequent start-stop cycles, vibration from mobile compressor diesel engines, and dusty outdoor site environments. High-grade bearing materials and anti-corrosion housing extend the working lifespan in rough field applications.

3. Full compatibility with matched Atlas Copco mobile air compressors

The OIS K-38 air end fits directly into the corresponding Atlas Copco portable screw compressor models. You do not need to modify machine frame, drive coupling, piping or mounting holes during installation. It guarantees perfect matching with your compressor’s control system, lubrication circuit and air outlet pipeline.

4. Protects your whole compressor system

Genuine Atlas Copco air end maintains proper internal oil sealing and rotor clearance. It prevents secondary damage to engine, gearbox and downstream filtration parts that often occurs when using non-genuine compression elements.

5. Full supply chain traceability

We source this air end directly from Atlas Copco (Shanghai) Trading Co., Ltd. Every product carries official factory identification marks. You receive complete product certification and shipping documents for customs clearance and equipment asset records.

Installation Procedures

Follow these professional installation steps for Atlas Copco OIS K-38 air end replacement. We recommend certified compressor technicians perform the whole installation process.

1. Prepare the mobile compressor: Shut down the diesel engine fully. Lock out and tag the power system. Release all residual compressed air from the air receiver and pipelines, then drain all compressor lubricating oil from the oil tank.
2. Remove protective canopy and related components: Take off the compressor outer canopy. Disconnect air inlet pipe, air discharge pipe, oil supply pipe and oil return pipe that connect to the old air end.
3. Detach drive coupling and fasteners: Remove bolts for the coupling assembly. Unscrew all mounting bolts holding the old air end to the compressor frame. Lift the worn air end carefully using proper lifting tools.
4. Clean the installation cavity: Clean all debris, old oil residue and metal particles inside the compressor housing cavity. Inspect the drive coupling, seals and bearings for extra wear; replace damaged auxiliary components before fitting new air end.
5. Mount new OIS K-38 air end: Lift the genuine 1616719480 air end into position. Align the coupling connection accurately. Tighten all mounting bolts to Atlas Copco specified torque values in cross sequence.
6. Reconnect all pipelines: Reinstall oil supply, oil return, inlet and discharge air pipelines. Fit new sealing gaskets at every joint to avoid air leakage or oil leaks.
7. Pre-lubricate the air end: Fill the correct Atlas Copco compressor lubricant into the air end before the first startup. Rotate the air end manually several full turns to confirm free rotation without jamming or scraping.
8. Reassemble canopy and complete inspection: Refit the compressor canopy. Check all pipe connections again. Refill the compressor oil tank with approved lubricant.
9. Commission and test run: Start the compressor with no-load test run first. Monitor discharge temperature, oil pressure, noise and air output for 30 minutes. Stop the machine and recheck all joints for leaks before returning the unit to field operation.
