1616585183: O.F.S. G-23 | ATLAS COPCO AIR END

When the integrity of your compressed air directly affects product quality, regulatory compliance, and operational uptime, every internal component matters. The Atlas Copco 1616585183 O.F.S. G-23 Air End is the heart of Atlas Copco’s oil-free screw air compressors — engineered in Belgium, tested to the highest industrial standards, and trusted by critical industries worldwide.

We supply this 100% brand-new, genuine original part, sourced directly from Atlas Copco (Shanghai) Trading Co., Ltd. With over ten years of authorized Atlas Copco distribution experience, Sekes ensures every unit you receive carries full traceability, original packaging, and manufacturer-backed warranty support.

Product Overview

The O.F.S. G-23 Air End is a precision-engineered compressor element purpose-built for Atlas Copco oil-free rotary screw air compressors. The designation “O.F.S.” (Oil-Free Screw) reflects its core design mandate: delivering compressed air that never contacts oil at any stage of the compression cycle. This makes it indispensable in industries where air purity is not optional but mandatory.

Manufactured at Atlas Copco’s advanced production facilities in Belgium, the G-23 model benefits from decades of R&D investment in screw compressor technology. Atlas Copco pioneered 100% oil-free compression and became the first manufacturer to receive ISO 8573-1 CLASS 0 (2010) certification — the gold standard for oil-free air quality. The G-23 Air End embodies that legacy of innovation and reliability.

The air end functions as the core compression module of the compressor. Inside, precision-matched male and female rotors mesh with extremely tight tolerances, compressing incoming air through progressive reduction of inter-lobe volume — all without a single drop of lubricating oil entering the air stream. The result is compressed air that meets the most demanding purity specifications, including ISO 8573-1 Class 0.

Key Product Advantages

Guaranteed 100% Oil-Free Air Output

The O.F.S. G-23 Air End operates on the proven Atlas Copco two-stage oil-free compression principle. Rotor surfaces are coated with specialized anti-wear materials, eliminating any need for oil injection during compression. The delivered air stream carries zero oil contamination — a prerequisite for pharmaceutical manufacturing, semiconductor wafer processing, food and beverage production, and medical device assembly.

Belgian Manufacturing Precision

Atlas Copco manufactures the O.F.S. G-23 in Belgium, where its ISO 22000-certified oil-free production facility operates under rigorous quality control protocols. Every air end undergoes dimensional inspection of rotor profiles, bearing clearance verification, and dynamic balancing before leaving the factory. This systematic quality assurance translates directly into superior in-field reliability and extended service life.

Direct Fit Compatibility

Designed and produced by Atlas Copco, the G-23 Air End installs as a direct, exact-fit replacement within compatible Atlas Copco ZT and ZR series oil-free screw compressor platforms. No field modifications, adapter kits, or dimensional adjustments are necessary. Technicians familiar with Atlas Copco service procedures can complete the replacement efficiently, minimizing planned downtime.

Full Warranty Coverage

Atlas Copco backs the O.F.S. G-23 with a 12-month warranty against design and manufacturing defects. This warranty remains valid only when the part is installed, operated, and maintained in accordance with Atlas Copco’s published technical guidelines. The use of non-genuine parts in associated components voids warranty coverage — a risk that Sekes customers entirely avoid by sourcing through authorized channels.

Original Packaging and Full Traceability

Every O.F.S. G-23 Air End supplied by Sichuan Sekes ships in Atlas Copco’s original protective packaging, complete with clear part identification labels, country-of-origin documentation (Belgium), and a serial number traceable to Atlas Copco (Shanghai) Trading Co., Ltd. This chain of custody documentation supports customs clearance, warranty registration, and internal compliance audits.

Optimized Energy Efficiency

Atlas Copco engineers the rotor profiles of the G-23 with AGMA A5/DIN 5 gear-grade precision. Tight inter-rotor and rotor-to-housing clearances minimize internal leakage, which directly reduces the specific energy consumption (kWh per m³) of the compressor. Over the operational lifetime of an industrial compressor, this efficiency advantage delivers measurable reductions in electricity costs.

Installation & Replacement Guide

Qualified Atlas Copco-trained service technicians should perform air end replacement. Always consult the official Atlas Copco service manual for your specific compressor model before beginning. The following steps outline the standard replacement procedure:

1. Safety Lockout/Tagout (LOTO): Isolate the compressor from the electrical supply, close all inlet and outlet valves, and depressurize the system completely. Verify zero pressure with a calibrated gauge before proceeding.
2. System Drain: Drain condensate and cooling water circuits fully. Allow sufficient cooldown time — the air end housing reaches high operating temperatures and must be at ambient temperature before handling.
3. Inlet and Outlet Disconnection: Disconnect the air intake filter housing and outlet piping from the air end flanges. Mark or photograph connection orientations to guide reassembly.
4. Coupling and Drive Disconnection: Remove the motor-to-air end coupling or drive belt/gear assembly according to the model-specific service manual. Retain all hardware for reinstallation or replacement inspection.
5. Air End Removal: Support the air end weight with an appropriate lifting device (the G-23 unit weighs 50 kg). Remove mounting bolts in the specified sequence and carefully extract the old air end from the compressor frame.
6. Inspection of Mating Surfaces: Thoroughly inspect all mating flanges, sealing surfaces, and mounting pads. Clean surfaces of gasket residue, corrosion, or contamination before installing the new unit.
7. New Air End Installation: Position the O.F.S. G-23 onto the mounting frame using the lifting device. Align all bolt holes and flanges. Install all fasteners hand-tight, then torque to Atlas Copco’s published specifications using a calibrated torque wrench.
8. Reconnection of Systems: Reconnect inlet and outlet piping, cooling water circuits, and the drive coupling. Install new gaskets and O-rings as specified. Verify all connections are secure and leak-free.
9. Commissioning and Verification: Restore power, perform a controlled startup per the commissioning checklist, and monitor operating pressures, temperatures, and vibration levels for the first 30 minutes of operation. Log all readings and compare against baseline specifications.
