SA Series (Air-Cooled)
SA Series Oil-Free Centrifugal Air Compressor
Turbo compressors designed with a focus on ease of maintenance (SA2100 and SA3100). 1,200–5,500 m³/h, 150–580 kW, discharge pressure 3.5–11.4 bar (abs). The split design allows inspection without removing the rotor.
Designed for easy inspection and maintenance: the SA series
The SA series is a turbo compressor designed with a focus on ease of maintenance.
Its split design allows inspection and maintenance without removing the rotor, and individually replaceable pinions and bull gears reduce the maintenance burden.
With no oil in the compression chamber, the 100% oil-free design supplies clean compressed air to ISO 8573-1 Class 0.
Key features
High-precision AGMA 12 & 13 gear system for lower noise and long service life
Individually replaceable pinions and bull gear for easy maintenance
Master impellers in 17-4 PH stainless steel
High-efficiency 5-axis machined impellers with a wide turndown range (API 672)
Split tilting pad journal bearings (pinion gears) for stable operation
Sleeve journal and taper land bearings minimize friction losses
RTD-capable bearings (SA3100 option)
Sealing system meeting API specifications — no separate sealing air required, preventing air and oil leakage
