Air compressor prices range from several thousand to hundreds of thousands of yuan, depending primarily on power and type: small screw compressors (7.5–22 kW) cost approximately ¥5,000–20,000 ($1,080–2,730); 22 kW screw models are around ¥20,000–80,000 (prices vary significantly by brand); a 55 kW permanent-magnet variable-frequency unit (bare machine) is about ¥65,000–69,000 (total installed cost: ¥83,000–95,000); and 110 kW class models start at ¥89,000—calculate your air consumption requirements before selecting the power rating.
I. Pricing by Power Rating (Core Factor)
7.5–15 kW: Small workshops/spray painting, $1,080–$2,400 (budget models: ¥4,676–¥5,344); 22–30 kW: Standard for hardware/stamping plants, ¥20,000–¥80,000 (Kaishan 22–110 kW series: ¥20,360–¥89,186); 37–55 kW: Mainstream for permanent magnet variable frequency (PMVF) models, bare unit ¥65,000–¥69,000 (Jaguar/Kaishan; complete system with dryer & air tank: ¥83,000–¥95,000); 75–110 kW+: Large factories, ¥89,000–¥217,000 (Fuda PMVF, Grade 1 energy efficiency: ¥136,850)—Doubling the power roughly increases the price by 1.5–2 times (calculate air consumption in m³/min first).
II. Classification by Type
Piston-type: Cheapest (a few thousand RMB), high noise + intermittent use;
Screw-type: Mainstream (continuous operation + low noise), 7.5–22 kW: $1,080–$2,730; Permanent Magnet Variable Frequency (PMVF): Saves 30–50% electricity (10–20% more expensive than fixed-speed models), 15 kW: approx. ¥6,000+ (industry promotions); Oil-free vs. Oil-lubricated: Choose oil-free for medical/food applications (50%+ more expensive); All-in-one units: Integrated main unit, dryer, and air tank (compact footprint)—Screw + PMVF is the industrial standard (electricity savings allow for cost recovery within a few years).
III. Brand Price Differences
High-end Imported: Atlas Copco (22kW $8,500–$11,000; 37kW $13,000–$17,000); Tier 1 Export-Grade: ZIQI/Liufuda (22kW $3,800–$5,200); Tier 2 Domestic: Kaishan/Fusheng (22kW $2,800–$3,800; 37kW $4,200–$5,500); Best Value: Jaguar/Zhongzheng (55kW bare unit: 65,000 RMB); Energy Efficiency: Tier 1 efficiency models cost 30%+ more (saves electricity long-term)—imported units cost 2–3 times more than domestic ones of the same power (consider budget vs. electricity costs).
IV. Hidden Costs
Dryer: Refrigerated/Adsorption dryer (20,000–80,000 RMB; removes moisture, prevents rust);
Air Receiver Tank: 0.3–2m³ (thousands to tens of thousands RMB); Filters: Main line + precision filters (determines air quality); Electricity: Air compressors are “power guzzlers” (account for 10–20% of factory electricity costs; permanent magnet VFD models save 30–50%); Maintenance: Oil/filter elements/oil separators (annual cost 5,000–20,000 RMB)—Total installed cost = Main unit + Dryer + Air receiver tank + Installation (allocate 20–30% of budget for auxiliary equipment).
V. Purchasing Recommendations
First, calculate air demand (total equipment air consumption in m³/min × 1.2 safety margin); second, determine power rating (select kW based on air demand); third, choose the type (screw + permanent magnet VFD is the mainstream; choose oil-free models based on industry requirements); fourth, compare brands (domestic for cost-effectiveness / imported for high-end quality / Grade 1 energy efficiency for long-term electricity savings); fifth, calculate the total cost (base unit + dryer + air receiver tank + 5 years of electricity and maintenance costs)—Air compressor price ranges: small units 5,000–20,000 RMB; 22kW 20,000–80,000 RMB; 55kW 65,000–95,000 RMB; 110kW 90,000–220,000 RMB.
Calculate air demand first → select power and type → calculate total cost of ownership → then make the purchase.
