The four questions we hear most from purchasing engineers sourcing compressors from China.
Oil-free compressors deliver ISO 8573-1 CLASS 0 air (0.00 mg/m³ oil), mandatory for food, pharmaceutical, and electronics manufacturing. Oil-injected compressors cost 30–40% less upfront but deliver air with 3–5 mg/m³ oil carryover, requiring coalescing filters for sensitive processes. If your product touches the air, choose oil-free.
Variable Speed Drive compressors track air demand and typically save 30–40% versus fixed-speed models in fluctuating-load applications. For a 100 HP unit running 5,000 hours/year at $0.10/kWh, payback is usually 12–24 months. Send us your load profile for a free energy audit.
Yes. Our H₂, CO₂ and CH₄ compressors can be supplied with ATEX Zone 1/2 certification, Ex d IIB T4 explosion-proof motors, gas detection and purge systems. IECEx certified units are also available. Please share your zone classification and gas group for a custom solution.
Air filter and water separator every 2,000–4,000 hours, airend overhaul after 50,000–80,000 hours. No oil changes, no oil disposal, no oil-carryover testing. Total cost of ownership is typically 15–20% lower than oil-injected over a 10-year horizon.
