Explore our premium product selections engineered to maximize system operational runtime and support top-tier oilless and lubricated industrial air compressor machinery.
Founded in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales. For over 15 years, the company has built a robust industrial chain system dedicated to high-precision engineering machinery, advanced synthetic fluids, and global clean-air delivery solutions.
Under our brand "Century Longhai" and through international strategic cooperation with British "A Ba" series, we construct solutions for high-demand environments. Our integration of mechanical architecture expertise with advanced lubrication science allows us to manufacture and optimize Oilless Air Compressors and dedicated high-performance maintenance materials. Backed by PICC China People's Insurance Company quality assurance, our industrial offerings perform exceptionally under the most extreme operating conditions.
Providing information gain on modern oilless technology: How mechanical coating developments and thermodynamic advances are transforming clean air compression.
Traditional compression chambers require oil film seals. Modern oilless compressors utilize aerospace-grade PEEK (Polyetheretherketone) and PTFE (Polytetrafluoroethylene) composite rings. These composites run with zero oil contact, completely eliminating air-borne hydrocarbon contamination risks.
Water-injected oilless screw systems use purified water as the cooling and sealing medium. Thermodynamic cooling is near-isothermal, raising energy efficiency by 15% compared to dry single-stage screw configurations while keeping the output 100% oil-free.
Permanent Magnet Variable Frequency Drives (PM VFD) match rotation speed dynamically with the actual airflow demands. This prevents idling losses, keeps system noise below 65 dB(A), and reduces industrial energy consumption rates by up to 35% annually.

| Maximum Working Pressure | Up to 15 Bar | Up to 10 Bar | Up to 16 Bar |
| Cooling Efficiency | Moderate (High thermal dissipation) | Low (Relies on air convection) | Excellent (Isothermal compression) |
| Maintenance Intervals | 3,000 Hours (Filters/Fluids exchange) | 10,000 Hours (Sealing ring check) | 8,000 Hours (Water filter system swap) |
| Recommended Applications | General Assembly, Heavy Manufacturing | Medical Devices, Dental, R&D Labs | Pharmaceuticals, Food & F&B, Semiconductors |
Across high-precision sectors, compressed air is classified as a utility equivalent to electricity and water. See how we configure custom systems for global target markets.
In fermentation, tablet pressing, and sterile packaging, air contacts active ingredients directly. Our Class 0 oilless solutions ensure zero hydrocarbon contamination, preventing costly batch rejections and meeting stringent FDA, GMP, and EU Annex 1 requirements.
Pneumatic transportation, automated packaging, and bottle blowing require dry, clean air. Eliminating oil ensures zero flavor alternation and eliminates food-grade health hazards. Our system meets ISO 22000 and HACCP hygiene standards.
Fabrication of microprocessors requires cleanrooms with extremely low levels of organic volatile compounds. Any oily trace in the air causes silicon wafer staining and circuit degradation. Our dry scroll compressors keep air fully cleanroom-certified.
Pneumatic paint sprayers require air free of moisture and oil to prevent surface blistering, cratering, and uneven bonding. Combining our oilless units with desiccant dryers produces premium, defect-free automotive finishes.
Longhai Technology operates from a modern production facility covering 131 acres, achieving an annual manufacturing capacity of 200,000 tons. Our facility integrates precision engineering lines and scientific quality control laboratories to satisfy standard orders and complex custom requests.
Equipped with computerized blending plants and automated filling lines, our machinery utilizes volumetric metering, keeping filling tolerance to a precise 1‰ to 2‰. This automation speeds up our filling processes by 20% to 35%, ensuring rapid production turnaround and stable shipping schedules for our global clients.
By keeping raw material stocks high, sourcing from top international refineries, and running on-site Quality Management systems, we shield B2B buyers from global pricing changes and supply shortages.
From design adjustments and component sizing to custom oil formulas and brand package designs, we provide full support for B2B distributors and equipment brands.
We develop high-performance synthetic lubricants, gear coatings, and hydraulic fluids custom-engineered to match your specific vehicle or machine specs. Our formulations are tuned for local climates and meet API, ACEA, and ISO standards to guarantee optimal machine life.
