ga15-vsd+ Specifications, Features & Compatibility Guide

5 bar through an oil-injected rotary screw mechanism.Powered by a 15 kW (20 HP) three-phase motor, this unit is built for continuous industrial duty without the downtime required by smaller reciprocating models.

Quick Answer

Yes, invest in the Atlas Copco GA15 if your Indian industrial operation demands reliable, continuous compressed air without interruptions. With its 15kW rotary screw mechanism delivering 27.7 CFM, it's designed for heavy-duty manufacturing tasks, unlike high-maintenance reciprocating models. This unit ensures steady, high-volume airflow essential for reducing downtime and improving efficiency in demanding production environments across India.

The Atlas Copco GA15 is perfect for Indian industrial workshops needing continuous 15kW rotary screw power and stable airflow for heavy manufacturing. Choose it for reliable, efficient operation; avoid if residential use or minimal upfront cost is your primary concern.

Product Overview
The Atlas Copco GA15 is a dedicated workshop compressor delivering 27.7 CFM at 7.5 bar through an oil-injected rotary screw mechanism. Powered by a 15 kW (20 HP) three-phase motor, this unit is built for continuous industrial duty without the downtime required by smaller reciprocating models. The stationary base-mount design, weighing between 420 and 470 kg, ensures stability for manufacturing air supply lines while occupying a 1255 mm by 692 mm floor space. Unlike portable units, the GA15 utilizes a direct gear-driven drive type to maintain peak efficiency during 380-415 V operation. Every GA15 includes an integrated smart controller with a digital display that monitors service indicators and provides overpressure protection. The 64-67 dB(A) noise output allows for installation closer to pneumatic tool workstations compared to louder open-frame compressors.

Engineering Analysis
The technical performance of the GA15 hinges on its 15 kW motor coupled with a direct gear-driven pump, which eliminates the slip-related energy losses found in traditional belt systems. This configuration ensures that the 780 LPM airflow remains consistent throughout high-demand shifts. The oil-injected lubrication type is critical for cooling the screw elements during the compression cycle, allowing for the continuous run capability specified for this 15 kW model. Safety is managed through a multi-stage system including a pressure relief valve, low oil shutdown, and thermal protection to safeguard the internal components under 7.5 to 10 bar loads. The 420–470 kg weight is housed in a powder-coated industrial steel enclosure that incorporates noise insulation and anti-vibration mounts, reducing the acoustic impact to 64-67 dB(A). For air quality management, the inclusion of a moisture separator effectively treats the 27.7 CFM output before it enters the shop air lines.
