Features of standard general oil-injected screw air compressor:

1. Screw host

Desnell original host, excellent compression efficiency, energy saving more than 5% compared with similar products in the market;

Exclusive patented linear design, while ensuring efficient operation, it can operate freely, durable and stable even under frequent start and stop conditions;

Excellent processing materials, extremely high processing progress, and sophisticated assembly technology ensure the life of the main machine head of each model.

2. Drive system

Elastic coupling connection, tight and no gap, no risk of wrong teeth;

Plum blossom multi-head high-efficiency coupling, 100,000 times of high-strength impact resistance test, to ensure stability and durability;

Imported coupling, excellent material selection, abrasion resistance, oil stain resistance, and aging resistance.

3. Air filter system

Pre-intake pre-filtering to prevent large particles from entering;

Card slot design, easy to clean and remove;

The air filter adopts a lock design, no additional tools are required to disassemble, and it is easy to open/buckle;

Selected high-quality air filter, dust removal filtration accuracy of 3 microns 99.9%; two-stage filtration of reverse flow rotation and paper fiber, suitable for various environments from plateau to flat ground;

The heavy-duty nano air filter is available for users in heavy dust production environments.

4. Oil and gas separation system

High-efficiency dedicated air compressed oil and gas separator, the oil content of the compressed gas is ≤3ppm;

The high degree of recycling of lubricating oil can effectively avoid the phenomenon of flying oil;

High-efficiency filter element, without frequent replacement, long service life;

The user-friendly design for disassembly and assembly of the oil-gas separation barrel cover can be easily replaced, saving time and effort.

5. Oil filter

Use well-known brand oil filters, highly clean and filter, prolong the service life of moving parts such as the machine head and gear box;

Durable, high-efficiency filter element, with greater capacity to filter oil and dirt, without frequent replacement; rotary installation, easy disassembly and assembly, and simple maintenance.
