We have extensive hands-on experience supplying and supporting the Atlas Copco 2904500069 SERVICE KIT for industrial customers worldwide. Based on our practical experience, the product packaging clearly displays the Atlas Copco brand identification together with the unique ten-digit part number, allowing users to easily verify product authenticity and traceability.
The service kit is packed in the original Atlas Copco brand carton box featuring the official Atlas Copco logo and standardized product labeling. Every package we supply is carefully inspected before shipment to ensure that the labels, seals, and packaging condition meet professional industrial standards.
From our direct sales and maintenance experience, this product demonstrates the consistent manufacturing quality associated with genuine Atlas Copco spare parts. The sealing components are accurately machined, the O-rings provide precise fitting dimensions, and the automatic drain valve assembly is manufactured to support reliable condensate discharge performance under demanding industrial operating conditions.
Many industrial users prefer using original maintenance kits because compressed air systems are highly sensitive to sealing quality and condensate drainage efficiency. Inferior sealing materials or inaccurate component dimensions can lead to leakage, pressure instability, condensate accumulation, or unnecessary shutdowns. Through our practical supply experience, the Atlas Copco 2904500069 SERVICE KIT consistently delivers dependable installation compatibility and operational stability.
We also observe that customers performing scheduled maintenance with original service kits often achieve longer equipment service life and lower long-term maintenance costs. Proper maintenance intervals help prevent internal moisture accumulation and protect downstream equipment from contamination or corrosion.

The Atlas Copco 2904500069 SERVICE KIT is primarily used for the maintenance and overhaul of WSD25-40 condensate drain systems. During compressor operation, condensate containing moisture, oil residues, and contaminants naturally accumulates inside the compressed air system. If condensate is not properly removed, it can negatively affect air quality, damage downstream equipment, and increase corrosion risks.
The automatic drain assembly included in this kit helps discharge condensate efficiently while minimizing compressed air loss. The included O-rings provide reliable sealing performance to prevent leakage and maintain pressure stability. By replacing worn sealing components and drain assemblies at recommended intervals, users can:
Maintain stable condensate drainage performance
Atlas Copco recommends scheduled maintenance according to operating hours and actual working conditions. For many industrial environments, this service kit supports maintenance intervals up to approximately 5000 operating hours. However, harsh operating environments with high humidity, dust, or continuous operation may require more frequent inspection and replacement.

Before beginning maintenance work, ensure that the compressor system is completely shut down and depressurized.
Step 1: Shut Down the Compressor System
Disconnect power supply and isolate the compressed air system to ensure safe maintenance conditions.
Step 2: Release Internal Pressure
Completely release residual air pressure from the condensate drain assembly before disassembly.
Step 3: Remove Existing Drain Components
Carefully remove the used automatic drain valve and old sealing rings. Inspect the installation area for contamination, corrosion, or debris.
Step 4: Clean the Installation Surface
Clean all sealing surfaces thoroughly to prevent contamination from affecting the new sealing components.
Step 5: Install New O-Rings and Drain Valve
Install the new O-rings according to their correct dimensions and positions. Ensure the automatic drain valve is properly aligned and securely installed.
Step 6: Inspect for Leakage
After installation, restart the system gradually and inspect all connections for leakage or abnormal operation.
