DS90A
CAMC
The CAMC DS90A oil-free screw compressor is designed specifically for the transportation of powder and granular materials. It is compatible with pneumatic conveying scenarios for powder and granular materials, and provides a dedicated motor drive solution for fixed locations. It meets the dual needs of vehicle mounted and fixed scenarios. With the mature manufacturing technology of CAMC, it has become the preferred supporting equipment in the field of powder and granular material transportation due to its small size, lightweight, and strong adaptability. The core advantage of this compressor is outstanding, with a compact size and an overall external dimension of only 604 * 281 * 432mm, which does not occupy too much vehicle space; Lightweight, with a net weight of 128KG and an overall weight of less than 220KG, it can effectively reduce the overall load of the vehicle; With a speed as low as 800-1000RPM, there is no need to match a dedicated power take-off, simplifying the matching process and reducing adaptation costs; The input angle of the transmission shaft is small, and the ground clearance height is reasonable, which can effectively avoid complex road conditions and collisions, greatly reducing the equipment failure rate; Easy to install, can adapt to most vehicle chassis models, and can be quickly put into use without complex modifications. Equipped with a silicon free and oil-free design, it outputs clean compressed air to avoid material pollution. It is suitable for conveying various types of powder and granular materials, helping to improve conveying efficiency and reduce operation and maintenance costs.

1. Strong adaptability and convenient matching: specially designed for the transportation of powder materials, with a speed of 800-1000RPM, no need to match a dedicated power take-off, simplifying the matching process, suitable for most vehicle chassis, and can be put into use without complex modifications.
2. Compact and lightweight, energy-saving and consumption reducing: The overall size is 604 * 281 * 432mm, with a small volume that does not take up space; The net weight is 128KG, and the supporting weight is less than 220KG. The lightweight design effectively reduces the overall vehicle load and indirectly improves operational economy.
3. Stable and durable, low failure rate: The input angle of the transmission shaft is small and the ground clearance is high, avoiding the risk of collision in complex road conditions and reducing equipment failures; Silicon free and oil-free design, avoiding material pollution while improving equipment durability, suitable for long-term high-frequency operations.
4. Diverse scenarios, flexible and practical: It can be used for conveying various types of powder and granular materials, providing motor drive solutions for fixed locations, taking into account both vehicle and fixed dual scenarios, and adapting to the material conveying needs of multiple fields such as building materials and mining.
1. The person in charge of a domestic powder material transportation enterprise said: “Our fleet of powder material dedicated vehicles are all equipped with CAMC DS90A compressors. The compact size of 604 * 281 * 432mm does not take up space, and the net weight of 128KG does not increase the burden on the entire vehicle. 800-1000RPM low speed does not require a dedicated power take-off, making it easy to install and adapt to all vehicle chassis. It has a high ground clearance and small input angle, with extremely low failure rate under complex road conditions in construction and mining areas. The silicon free and oil-free design can also effectively protect materials from pollution.”
2. A procurement manager for a building materials logistics company in Southeast Asia: “We have both vehicle mounted material transportation needs and fixed site transportation needs. The motor drive solution of this compressor is perfectly suitable for dual scenarios. It is small in size, light in weight, and compatible with our transportation vehicles. It simplifies the supporting process without the need for a dedicated power take-off, is easy to install and runs stably, has a low failure rate, and can effectively adapt to the transportation of various types of powder materials, greatly reducing our operation and maintenance costs. It has been purchased in bulk and used as a supporting equipment.”

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.
