Application

Screw Air Compressor

Material

Stainless Steel

This 1616578982 air end is specifically calibrated for Atlas Copco GA30+ and GA37 VSD+ compressor series (model years 2018–present). Unlike previous universal models, it aligns with the unique mounting dimensions, shaft configurations, and pressure requirements of these two high-demand series. To confirm fit, we’ve included a detailed Compatible Compressor Table below—no more guesswork about whether the part will work with your unit.

Compatible Atlas Copco Compressor Series	Model Year Range	Key Matching Features
GA30+ Screw Compressor	2018–2025	30kW motor, 8.5 bar standard pressure, vertical mounting
GA37 VSD+ Variable Speed Compressor	2019–2025	37kW VSD motor, 10 bar max pressure, integrated oil circuit

Key Features

Core Value for Targeted Users

For operators of GA30+ and GA37 VSD+ compressors, this air end solves a critical pain point: generic replacements often require modifications (e.g., re-drilling mounting holes, adjusting shaft couplings) that risk equipment damage. The 1616578982 model eliminates this hassle—its mounting holes, shaft length, and oil port positions are identical to the original Atlas Copco part, enabling "plug-and-play" installation.

Precision Commitment

Every 1616578982 air end undergoes a 3-step model-specific validation process before leaving our factory:

Dimensional matching: Laser-scanned against Atlas Copco’s original 1616578982 blueprints to ensure ±0.003mm tolerance alignment.
Compressor integration test: Mounted on a genuine GA37 VSD+ unit to verify airflow, pressure, and noise levels match OEM standards.

Key Differentiators

Unlike our previous universal air end models, the 1616578982 incorporates unique design elements tailored to the GA30+ and GA37 VSD+ series’ operating characteristics. Here’s how it delivers unmatched value:

VSD-optimized Rotor Design

The GA37 VSD+ series uses variable-speed drives (VSD) to adjust motor speed based on air demand. Our 1616578982 air end features variable-pitch rotor profiles—a design not found in standard air ends. This allows the rotors to maintain optimal compression efficiency across a wide speed range (1,200–3,000 RPM), reducing energy waste by up to 22% compared to generic air ends that only perform well at fixed speeds.

High-Pressure Sealing System

The GA30+ and GA37 VSD+ compressors often operate in high-humidity or dusty industrial environments (e.g., automotive workshops, metal fabrication plants). To address this, the 1616578982 air end is equipped with a triple-layer sealing system:

Outer layer: Silicone dust shield to block particulate matter from entering the housing.
Middle layer: Fluorocarbon (Viton) oil seal resistant to high temperatures (up to 120°C) and industrial oils.
Inner layer: Nitrile O-ring with pressure-activated expansion to prevent air leakage under variable load.

Integrated Oil Distribution Channel

Unlike previous air ends that rely on external oil lines, the 1616578982 features an internal oil distribution channel—matching the original Atlas Copco design. This channel delivers oil directly to the rotor bearings and compression chamber in precise quantities, reducing oil consumption by 15% and minimizing the risk of oil starvation (a common cause of premature air end failure in GA30+/GA37 VSD+ units).
