50L Oil-Free Silent Air Compressor with 276L/min High Flow and Double Head Motor
Unstoppable Industrial Air Power: The SP-50S Dual Cylinder Compressor
The SP-50S Oil-Free Air Compressor represents the pinnacle of our heavy-duty pneumatic lineup. Engineered for large-scale industrial workshops and demanding professional environments, this beast features a massive 50L steel tank and a powerful dual-cylinder (double head) motor system. With a staggering 276L/min air displacement and a combined 2900W (1450W*2) rated power, it delivers an unmatched, steady airflow that can run multiple heavy pneumatic tools simultaneously without a hitch.
Unlike single-cylinder compressors, the SP-50S dual-head design not only provides superior air volume but also enhances heat dissipation, ensuring continuous heavy-duty operation without overheating. Thanks to its 100% oil-free technology, it outputs pure, clean air, making it absolutely essential for professional paint spraying, automotive body shops, and medical-grade applications.
Built to withstand the rigors of daily industrial use, the SP-50S is mounted on a heavy-duty wheel kit and features an extended handle for easy site navigation. Whether you are powering impact wrenches, sandblasters, or a full array of carpentry nailers, this high-capacity machine is the reliable backbone of your operation. We offer extensive OEM/ODM services for global distributors seeking top-tier pneumatic solutions.
- Dual-Cylinder (Double Head) Motor System
Features two independent 1450W motors, generating a massive 276L/min airflow. This dual-head design ensures stable pressure and faster tank recovery even under extreme loads.
- Massive 50L Industrial Tank
The large 50L reservoir acts as a huge air battery, significantly reducing motor cycling and providing extended runtimes for heavy consumption tools like sandblasters and grinders.
- High-Efficiency Heat Dissipation
The dual-motor architecture spreads the workload, running cooler and smoother than single-motor systems, making it perfect for all-day continuous industrial use.
- 100% Oil-Free & Ultra-Quiet
Eliminates oil changes forever and guarantees contaminant-free air. The low-noise design creates a quieter, safer, and more productive working environment.
- Heavy-Duty Mobility
Equipped with industrial-grade rubber wheels and a reinforced pull handle, allowing operators to easily move this powerful machine across uneven workshop floors.
- Precision Control & Safety
Features an easy-to-read dual-gauge control panel, automatic pressure switch (cut-in/cut-out), and thermal overload protection up to 0.8MPa (8 Bar).

Our 50L heavy-duty oil-free air compressor is built for the most demanding industrial and commercial tasks:
- Automotive Body Shops: Running heavy impact wrenches, grinders, sandblasters, and spray guns continuously.
- Industrial Manufacturing: Powering multiple pneumatic assembly tools, rivet guns, and automated production lines simultaneously.
- Commercial Spray Painting: Providing a massive, steady, and oil-free air supply for flawless large-scale furniture or automotive painting.
- Construction & Renovation: Operating multiple concrete nailers, breakers, and sanders on large job sites.
- Woodworking Factories: Powering dozens of pneumatic nail guns and staplers for mass furniture production.
- Agriculture & Mining: Running high-demand pneumatic tools for heavy equipment maintenance.
Compared to single-motor compressors, the SP-50S offers unmatched advantages for heavy users:
- Unbeatable Air Volume: The 276L/min flow rate is nearly double that of standard single-head compressors, handling high-consumption tools with ease.
- Continuous Heavy-Duty Operation: The 50L tank and dual motors prevent pressure drops, allowing for non-stop work without waiting for the tank to recharge.
- Superior Cooling System: Two motors working together generate less heat individually, ensuring longer machine life and reduced downtime.
- Multi-Tool Capability: Easily powers 3-5 pneumatic nail guns or multiple sanders at the same time without losing pressure.
- Zero Maintenance Costs: 100% oil-free operation means absolutely no recurring costs for oil changes, filters, or hazardous waste disposal.

Q1. What is the main advantage of having two motors (Double Head) over a single motor?
A: The dual-motor system provides significantly higher air displacement (276L/min). It allows the compressor to recover air much faster, meaning you can run high-consumption tools like sandblasters or multiple nail guns simultaneously without the pressure dropping.
Q2. Can this compressor run heavy tools like sandblasters?
A: Yes! With a massive 50L tank and 276L/min airflow, the SP-50S is specifically designed to handle high-consumption industrial tools that would stall smaller compressors.
Q3. Is it truly oil-free?
A: Absolutely. The SP-50S uses 100% oil-free piston technology. You will never have to add, check, or change oil, and the air output will be 100% clean and free of oil mist.
Q4. How heavy is the 50L unit? Is it easy to move?
A: While the 50L tank makes it heavy, it is built on a sturdy industrial chassis with large rubber wheels and an ergonomic pull handle. One person can easily move it around the workshop without difficulty.
Q5. Can I use this for professional automotive painting?
A: Yes. Because it is oil-free, it provides the clean, contaminant-free air required for high-quality paint finishing. (We recommend adding a moisture trap/filter for optimal results).
Q6. Do you offer 110V versions for the US/Canada market?
A: Yes, we can customize the motor voltage to 110V/60Hz and equip it with standard US/Canadian plugs. Please specify your target market when requesting a quote.
Q7. What is the warranty for this heavy-duty model?
A: We typically offer a 1 year warranty on the dual motors and main unit against manufacturing defects, ensuring your peace of mind.
Q8. Do you supply spare parts for the dual-motor system?
A: Yes, we supply all necessary spare parts, including individual motors, pressure switches, check valves, and wheels, to ensure you can provide excellent after-sales support to your customers.
