Types of Stage V Air Compressors
The stage V air compressors produced by our company mainly include the following types
01
Jackhammer Air Compressor
The CFAIR 50cfm air compressor is an excellent performance device. Its exhaust volume is 50cfm, which can meet the gas demand within a certain range. It is equipped with a Kubota engine. As a well-known brand, Kubota provides reliable power support for the operation of the air compressor.
02
Bridge Air Compressor
The CFAIR 190cfm portable air compressor is designed and manufactured with great ingenuity. It uses a Yanmar engine, which has excellent mechanical performance, can output power stably, and accurately adapt to the 7bar pressure condition and the exhaust volume of 190cfm, ensuring the efficient operation of the air compressor.
03
Quiet Compressor
The air compressor is equipped with the well-known Cummins engine. The excellent quality of the Cummins brand ensures the reliability and durability of the engine, laying a solid foundation for the continued efficient operation of the air compressor.

Advantages of Stage V Air Compressors
Advanced technology: Incorporates the latest advancements in emission reduction.
Environmental compliance: HVO compatible to reduce carbon footprint by up to 90%.
Provides 100% oil-free air: Complies with ISO 8573.1 Class 0 air quality standards.
Energy efficiency: Potential to reduce total energy expenses, given the significant energy cost contribution of compressed air.
Utility: Ideal for situations with limited utility availability or remote locations.
Solar battery charger: Ensures the compressor is always ready to start with no auxiliary power required.

● Renewable energy projects: Wind farms, and renewable energy installations that require low emissions.
● Food processing: Areas where low emissions and oil free air are necessary to avoid contamination and meet industry standards.
● Sensitive industrial applications: Industrial facilities requiring minimal environmental impact for both their facility and processes.
● Marine and offshore projects: Operations on or near water where emissions control are critical to adhere to emissions legislation.
● Infrastructure projects: Bridge, and rail construction, for projects needed to meet stringent emission guidelines.
Storage Precautions for Stage V Air Compressors
Plan ahead and prepare your space.
Before moving your compressed air system into storage, ensure you’ve prepared an adequate storage space. Find a clean, dry location to store your compressor where you can maximize space efficiency. You should almost always opt to store your compressor indoors, unless you can guarantee your compressor is stored in an outdoor area with a stable, regulated temperature and proper insulation. Basements are generally not recommended, as they are at risk of flooding, and storage sheds must be sufficiently insulated from harsh outdoor conditions that could lead to rusting.
Prep your air compressor.
To prepare your air compressor for storage, begin by switching it off. Reduce your machine’s air pressure with the regulator knob until it hits zero, then unplug the compressor from the wall. Alternatively, if your compressor operates on a battery, turn off your compressor and remove the battery— which should be kept in a similarly dry, clean storage space and ideally stored with a 40 percent remaining charge.
Have your compressor inspected.
Preparing your air compressor for storage offers an ideal opportunity for a professional audit. A professional servicer can identify any operational flaws or pre-existing wear to your compressor so that you have a comprehensive record of your machine’s state before it goes into storage. Evaluating your compressor’s energy efficiency, pressure performance, and all of its working parts — including valves, filters, and piping — guarantees that it will run smoothly whenever you decide to remove it from storage.
Regulate your storage space.
Finally, it’s necessary to monitor your storage space throughout the storage period to ensure that it remains clean and properly ventilated. Keep the area dry and out of direct sunlight. Your storage area should be kept at an ambient temperature of around 59 degrees Fahrenheit, and if you are storing a battery, ensure it is never stored in freezing temperatures or in conditions where temperatures exceed 100 degrees. Regularly sweep and dust the storage space to ensure grime and particulate cannot find their way into your compressor’s filters or openings.

Our Factory
Jiangxi Gas Compressor Factory began as Ganzhou Machinery Factory after the public-private partnership in 1951. It was renamed Ganzhou Machinery Factory in 1955, Gannan General Machinery Factory in 1958, and Jiangxi Gas Compressor Factory in 1969. Jiangxi Gas Compressor Factory was always at the forefront of the industry in terms of technical strength in the 1970s and 1980s. As a result, the First Ministry of Machinery Industry at that time designated Jiangxi Gas Compressor Factory to conduct research and production of many new models.
