Working Principle

The OFT E-11 oil-free tooth air end operates based on precision meshing rotor compression technology developed independently by Atlas Copco. Unlike traditional oil-injected screw air ends, this unit completely separates lubrication systems from the compression chamber to achieve true oil-free air compression.

Two high-precision asymmetric male and female rotors rotate in opposite directions inside the air end. External synchronous gears keep the rotors in perfect alignment without any physical contact between rotors or the inner wall of the compression cavity. This contact-free design removes the need for lubricating oil in the compression area. As the rotor rotation proceeds, the air intake volume gradually shrinks along the compression channel, which continuously compresses inhaled atmospheric air and raises air pressure stably.

The sealed independent gear and bearing lubrication system provides lasting lubrication for transmission components without mixing any oil vapor into the compressed airflow. The optimized rotor profile minimizes internal air leakage and pressure loss during operation. It ensures the air end delivers stable air volume and pressure output while maintaining 100% oil-free air quality, fully meeting ISO 8573-1 Class 0 oil-free air certification requirements for high-standard industrial production.

Product Advantages

As a genuine Atlas Copco original air compressor head, the 1616710781 OFT E-11 air end shows outstanding advantages in quality, performance, compatibility and service life compared with ordinary alternative parts.

Authentic Original Factory Quality & High Authority

We source all air ends directly from Atlas Copco (Shanghai) Trading Co., Ltd. Every product carries official factory production records and qualification certification. Strict factory testing procedures ensure each unit meets global unified manufacturing standards of Atlas Copco. Users avoid quality risks from unqualified replacement parts and obtain completely consistent performance with the original equipment.

Pure Oil-Free Air Output for High-End Industries

The contact-free rotor compression structure completely isolates oil pollution. It provides ultra-clean compressed air with zero oil content, which effectively protects precision production equipment, finished products and experimental environments. It perfectly adapts to strict industrial scenarios that prohibit oil contamination.

High Energy Efficiency & Stable Operation

The upgraded asymmetrical rotor structure reduces internal air leakage to the lowest level. It improves compression efficiency and lowers equipment operation energy consumption. The precise gear transmission system ensures smooth rotor operation with low noise, low vibration and stable air pressure output. It supports long-term continuous industrial operation without performance attenuation.

Perfect Model Compatibility & Easy Replacement

This new part 1616710781 fully replaces the old model 1616547081 with zero adaptation difference. It matches multiple mainstream Atlas Copco oil-free compressor models. Users conduct direct plug-and-play replacement without modifying equipment pipelines or programs, which greatly shortens maintenance downtime.

Durable Structure & Low Maintenance Cost

The air end adopts high-strength wear-resistant alloy materials and precision integral casting technology. The rotor surface undergoes special anti-corrosion and wear-resistant treatment. It extends the overall service life and reduces daily failure rates. The independent lubrication system simplifies later maintenance work and cuts long-term equipment operation costs.

When to Replace the OFT E-11 Air End

Timely air end replacement maintains stable compressor operation and avoids production losses. We summarize clear replacement judgment standards based on Atlas Copco official maintenance specifications and practical industrial operation experience.

First, replace the air end when the compressor shows obvious insufficient air volume and unstable outlet pressure. If the system maintains normal operating frequency but cannot reach the rated pressure and airflow, internal rotor wear and air leakage usually cause the problem, and air end replacement becomes the fundamental solution.

Second, proceed with replacement when the equipment produces abnormal vibration and sharp running noise. Long-term high-load operation causes rotor wear, gear clearance increase and component aging, which generate abnormal noise and vibration. Continuous operation will accelerate component damage and even cause equipment failure.

Third, replace the unit when the compressed air quality declines obviously or trace oil contamination appears. Although oil-free compressors have no oil injection in the compression cavity, aging sealing components may lead to lubricating oil vapor leakage and affect air purity.

Fourth, follow the fixed maintenance cycle. Under normal industrial continuous operation, users need to replace the OFT E-11 air end after reaching the factory-suggested service life to prevent sudden failure and ensure long-term stable equipment operation.

Standard Installation Steps

Professional and standardized installation ensures the maximum performance and service life of the 1616710781 OFT E-11 air end. We provide complete official installation steps for user reference:

• Step 1: Pre-installation Preparation & Safety Lockout Cut off the compressor main power and release all residual pressure inside the equipment to ensure zero-pressure and zero-power safety status. Prepare professional disassembly tools, clean cotton cloths and matching auxiliary accessories, and clean the equipment installation area to avoid dust and impurities entering the compression cavity.
• Step 2: Disassemble the Old Air End Remove the equipment shell and connecting pipelines in sequence. Mark the wiring and pipeline positions to avoid installation errors. Disassemble the fixing bolts of the old air end, separate the air end from the motor and transmission components, and take out the old unit completely. Clean the installation base and connecting surfaces thoroughly to remove residual dirt and scale.
• Step 3: Install the New OFT E-11 Air End Place the new genuine air end stably on the installation base. Align the transmission interface and pipeline interface accurately. Tighten the fixing bolts evenly according to the factory torque standard to ensure stable installation without offset. Connect the air pipeline, lubricating oil pipeline and signal lines in the original marked order.
• Step 4: Conduct Sealing & Lubrication Inspection Check all connecting interfaces for tightness to eliminate air leakage and oil leakage risks. Inject the official matched lubricating oil for oil-free compressor gears and bearings according to the standard liquid level to ensure the normal operation of the independent lubrication system.
• Step 5: Debug & Test Run After completing installation, conduct no-load test run first to check for abnormal noise, vibration and leakage. Then perform load debugging to verify whether the air pressure, air volume and operating parameters reach the rated standard. Confirm all indicators are normal before putting the equipment into formal production operation.
