Product Overview
The BDW single cylinder air compressor adopts an innovative four crank rocker transmission mechanism, which converts the circular motion of the crank into 90 degree reciprocating motion through a precisely designed transmission shaft, achieving stable and wave free power transmission. Its core feature lies in the periodic working cycle of the cylinder - independently completing the four stages of intake, compression, exhaust, and expansion, forming a continuous and efficient compressed air output.
The unique sealing system adopts a self-lubricating design with lubricating oil, forming a dynamic oil film seal between moving parts to ensure complete sealing inside the cylinder. This design not only achieves 100% oil-free purity of compressed air (compliant with ISO 8573-1 Class 0 standard), but also maintains pressure fluctuations of ≤ 0.1 bar during 2000 hours of continuous operation by precisely controlling the amount of lubricating oil and strengthening the connecting rod structure.
The crankcase optimized for heavy-duty working conditions is made of ductile iron cast as a whole, combined with a four crank phase difference layout, effectively balancing mechanical vibration, making this model particularly suitable for industrial manufacturing, pneumatic tools and other work scenarios that require continuous high-pressure air supply.

Product Advantages
Efficient and stable power output
Adopting a four crank rocker transmission mechanism, it achieves 90 ° precise reciprocating motion, stable output pressure (fluctuation ≤ 0.1 bar), and ensures the reliability of continuous operation.
100% oil-free pure air
Innovative self-lubricating sealing system achieves complete sealing through dynamic oil film, meeting the ISO 8573-1 Class 0 oil-free standard and meeting the gas requirements of precision instruments.
Heavy duty and durable design
Ductile iron crankcase and reinforced connecting rod structure, combined with 5.5L ± 0.1L precise oil control, support 2000 hours of uninterrupted operation, suitable for industrial grade high-strength use.
Intelligent vibration control
The four crank phase difference layout effectively counteracts inertial forces, reduces vibration amplitude by 40%, and reduces noise by ≤ 72dB, significantly improving equipment lifespan and operational comfort.
Customer Reviews
Feedback from German automotive parts manufacturers
"The BDW compressor has been running continuously for 18 months in our automated production line, and its stable 0.1 bar pressure fluctuation fully meets the requirements of precision assembly. The oil-free feature extends the lifespan of pneumatic tools by 30%, but it is recommended to add a low-temperature start assist device to the European version."
Evaluation by Technical Supervisors of Southeast Asian shipyards
"The 20 BDW compressors used in the dock maintain dry air output even in an 85% humidity environment, and the self-lubricating system solves the problem of salt spray corrosion. The vibration resistance of ductile iron structure eliminates the need for additional shock-absorbing bases for deck installation, and the maintenance cycle is extended by 50% compared to traditional models."

FAQ
1.Q: What is the recommended continuous working time for the device?
A: We recommend no more than 4 hours of continuous operation at a time. After that, shut down the machine to cool for 15-20 minutes to avoid overheating and extend the device’s lifespan.
2.Q: Does the oil-free device require regular maintenance?
A: Yes. We advise checking and cleaning the air intake filter monthly (replace if heavily clogged), and inspecting the body seals quarterly to prevent air leaks that reduce efficiency.
3.Q: Can the working pressure be adjusted manually?
A: The working pressure of this model is preset to 2 bar and cannot be adjusted independently. For higher pressure requirements, please select a model with the corresponding pressure rating.
