2906045200: ZR400-425 16000H MAINTENANCE KIT

As an Atlas Copco distributor, we supply the genuine Atlas Copco 2906045200 ZR 400-425 16000H Maintenance Kit — a brand-new original service package sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. Every kit we deliver carries full manufacturer traceability, giving you complete confidence in authenticity and quality from the moment it arrives.

Product Overview

This comprehensive kit provides all necessary components for the major 16,000-hour service interval, ensuring your critical equipment continues to operate at peak performance. For industrial engineers and maintenance professionals, this kit simplifies complex overhauls by bundling every required genuine part into a single, convenient package, guaranteeing your compressor runs smoothly and efficiently for another full lifecycle.

Each compressor maintenance package is assigned an Atlas Copco part number, which reduces administrative burden and creates a purchase order that is simple and easy to track. Additionally, the cost of a maintenance package is less than the total cost of the components if ordered individually.

Non-genuine spare parts are not specifically manufactured for your compressor and can put the integrity of your equipment at risk. Non-genuine spare parts may also have a shorter service life, thereby reducing compressor performance and increasing energy consumption. Genuine spare parts guarantee excellent air quality and operating performance.

Technical Specifications

Kit Components

Applicable Industries

The Atlas Copco ZR 400-425 series oil-free air compressors — and therefore this maintenance kit — serve industries where 100% oil-free compressed air is a strict operational requirement. Typical applications include pharmaceutical manufacturing, food and beverage production, electronics assembly, automotive painting, hospitals and medical facilities, chemical processing, and textile production. In all of these sectors, air purity directly impacts product quality and regulatory compliance, making the use of genuine maintenance components non-negotiable.

Installation Steps

We strongly recommend that a certified Atlas Copco service technician or a qualified maintenance engineer perform the 16,000-hour overhaul. The following steps outline the general procedure:

1. Safety isolation — Shut down the compressor completely. Disconnect it from all power sources, depressurize the system to zero bar, and allow all components to cool to ambient temperature before beginning work.
2. Review documentation — Consult the official Atlas Copco ZR 400-425 service manual for torque specifications, component sequences, and model-specific guidance before disassembling anything.
3. Unpack and inspect the kit — Open the 2906045200 kit packaging and verify that all listed components are present and undamaged. Match each component against the kit contents list before proceeding.
4. Complete the 4,000-hour sub-kit tasks first — The kit includes a ZR 300-425 4,000H Maintenance Kit as a sub-component. Perform all tasks associated with that interval (filter replacements, drain valve servicing, inlet valve inspection) as part of the overall 16,000-hour workflow.
5. Replace filter elements — Remove and discard both the air filter element and the oil filter elements. Install the new genuine filter elements from the kit, ensuring correct seating and seal integrity on all housing interfaces.
6. Service the drain and check valves — Remove the existing drain valve assemblies and check valve kit components. Install the new drain valve kits and check valve kit supplied in the 2906045200 package, using new seal washers (M32, M20, and Dowty 1/4) and O-rings as specified.
7. Replace the inlet valve kit — Remove the existing inlet valve assembly. Fit the new Kit Valve Inlet from the package, replacing all associated rubbers from the Set Rubbers component. Verify valve movement and seating before closing the housing.
8. Install mufflers and silencer — Replace both mufflers and the silencer with the new units included in the kit. Confirm all mounting points are secure and that there are no air gaps or loose fittings.
9. Install membrane and remaining seals — Replace the membrane component along with all remaining O-rings, washers, and the washer channel as specified in the service manual for this interval.
10. Reassembly and leak check — Reassemble all panels and access covers. Restore electrical connections. Perform a cold-start run with no load, check for air and oil leaks, and verify all sensor readings before returning the compressor to full production load.
11. Update service records — Log the 16,000-hour service completion date, the kit part number (2906045200), and the technician details in the compressor’s maintenance history.

Frequently Asked Questions

Q1: Which Atlas Copco compressor models does this kit cover?
A1: Part number 2906045200 covers the Atlas Copco ZR 400-425 stationary oil-free air compressor range, specifically designed for the 16,000-hour major maintenance service interval on these models. If you are unsure about compatibility with your specific unit’s serial number or configuration, contact us and we will confirm before you order.

Q2: Is this kit brand new and sourced from the original manufacturer?
A2: Yes, without exception. We procure this kit exclusively from Atlas Copco (Shanghai) Trading Co., Ltd., the authorized Atlas Copco entity operating in China.

Q3: Why should I buy a complete kit instead of ordering individual parts separately?
A3: Buying a kit is often a smarter and more convenient choice for machinery maintenance. Kits are curated by manufacturers to include all the necessary components for a specific task, ensuring compatibility, efficiency, and ease of use. Guaranteed compatibility means all parts are designed to work seamlessly together, eliminating the risk of mismatched components, which can lead to inefficiencies, malfunctions, or even damage to the equipment. A single kit purchase also reduces your administrative workload and simplifies procurement tracking.

Q4: Does this kit come with installation instructions?
A4: Genuine Atlas Copco service kits include clear and easy-to-follow instructions. This guidance helps your in-house maintenance team perform the installation correctly, ensuring you benefit fully from every new component.For complex 16,000-hour overhauls, we also recommend engaging an Atlas Copco-certified technician to ensure all torque values and sequences meet factory specifications.

Q5: What are the risks of using non-genuine parts for the 16,000-hour service?
A5: Non-genuine spare parts may have a shorter service life, thereby reducing compressor performance and increasing energy consumption. Genuine spare parts guarantee excellent air quality and operating performance. For ZR series oil-free compressors operating in sensitive industries, any compromise in air purity caused by substandard components can trigger regulatory non-compliance and costly production shutdowns — risks that far outweigh any short-term savings on parts.
