- 1997 — Turbo Air 3000 introduced
- 1999 — TA-6000 introduced
- 2001 — Turbo Air Cooled 2000 launched; TA-11000 and Vantage control panel introduced
- 2005 — Turbo Air 2020 and Turbo Air 9000 launched; first centrifugal compressor capable of 40 bar (600 psig) for standard industry
- 2007 — First centrifugal compressor manufacturer to achieve ISO 8573-1 Class 0 certification
- 2015 — Ingersoll Rand acquires Cameron's Centrifugal Compression Division

Key engineering features of the Turbo-Air series
Across all TA models, several design features are shared and are central to both performance and maintenance planning:
- Impellers — precision-machined on 5-axis equipment to advanced aerodynamic designs for high efficiency and wide operating range
- Optimized vanes and diffusers — matched to each impeller stage to maximize pressure recovery and minimize surge
- Low-pressure lubrication system — simplified oil circuit that reduces auxiliary power demand and maintenance complexity
- Easy-maintenance coolers — intercoolers and aftercoolers designed for straightforward inspection, cleaning and bundle replacement
- Long-life pinion bearings — tilting-pad or journal bearing arrangements engineered for extended service intervals
- Non-contacting, non-lubricated labyrinth air seals — provide oil-free air delivery with minimal wear over the seal's service life
- Maestro Universal control system — microprocessor-based control panel for monitoring, protection and sequence operation
Typical applications across industries
Turbo-Air compressors serve a broad cross-section of industries where reliable oil-free air is essential:
- Steel & metal production — plant air, instrument air, process air
- Mining — ventilation, pneumatic conveying, instrumentation
- Textile — weaving, spinning and pneumatic conveying of fibers
- Food & beverage — oil-free air for bottling, packaging and processing
- Automotive — paint shops, assembly lines and pneumatic tools
- Pharmaceutical — clean, oil-free air for production and packaging
- Chemical & petrochemical — process air, nitrogen generation and instrument air
- Power generation — boiler combustion air, soot blowing, instrument air
- Air separation — feed air for oxygen and nitrogen plants
Spare parts and maintenance for Turbo-Air compressors
Like all centrifugal compressors, Turbo-Air machines consume a predictable set of spare parts over their service life. The most frequently replaced items include:
- Air seals and oil seals — labyrinth edges wear with every start-stop cycle; almost always replaced during a major overhaul
- Journal and thrust bearings — tilting-pad bearings on the high-speed pinion shaft and bull gear bearings
- Impellers and diffusers — subject to fouling and erosion; inspect and dye-penetrant test, repair or replace as needed
- Intercooler and aftercooler bundles — fouled tubes raise discharge temperature and reduce efficiency; replace when cleaning is no longer effective
- Gears — inspect for pitting and wear; replace when backlash or tooth damage exceeds limits
- Consumables — air filter elements, oil filter elements, oil mist separators, gaskets and coupling elements
For planned shutdowns, Turbomax assembles complete overhaul service kits per machine serial number — seals, bearings, filters, gaskets and coupling elements packed as one set, so nothing is missing when work starts. Critical parts such as impellers, rotors and bearings are manufactured to order with short lead times, while fast-moving consumables are usually in stock for immediate shipment.
