Selection of compressed air filter

Sometimes, the quality of compressed air cannot be solved by connecting a device to a compressed air supply station. In order to obtain the most suitable mechanical working efficiency and product quality, the compressed air user needs an overall understanding of the quality of the compressed gas he will obtain in the internal air supply system or in a separate department. Iso8573 can not answer this question, which requires the aapc compressor, compressed air and vacuum technology trade associations to provide adequate advice to users of compressed air.

To provide particles as little as possible on an as-needed basis The standard provided by the iso standard is “on request, with as little particles as possible”. Because in addition to technical requirements, aapc member companies have carefully considered various issues when drafting standard documents, and even considered this issue from the perspective of user costs. Of course, investment costs are an important part: High compressed air quality means expensive purification equipment or high-quality purification equipment. However, what is more important is the operating cost of the equipment.

Nanjing Ruishiji International Trading Co., Ltd. can really provide users with some real help.

Compressed air treatment consists of several components (filter or dry filter combiner for pre-filtration, secondary filter/concentrator and concentration processing, etc.), and product experts can help you to plan a complete solution. Those who want to choose their own filters must first familiarize themselves with the filter-related functional data and be able to set uniform initial conditions (pressure, flow, ambient and inlet temperatures, relative humidity, etc.).

Is an oil-free compressor better?

When dealing with issues such as dew point, retention, and residual oil content, people will soon find that "compressed air quality" is a very complicated matter. At some point, some users may prefer one of the most basic and simple options - using an oil-free compressor. Their idea is that using an oil-free compressor at least for residual oil content is no longer a matter of concern. This not only simplifies the handling of equipment, but it also makes it possible to obtain compressed air more economically.

In fact, the oilless compressor simply does not inject oil into the compression chamber. However, the bearings and other components of the compressor need to be lubricated. This kind of compressor can also reach the compressed air. The same is true for inhaled air, which is also easily contaminated (remember, the average single-item dust content is 20 mg/m3). Therefore, purification treatment is indispensable anyway. Especially when the oil-free compressor produces compressed air at a higher temperature than the compressed air produced by the oil-lubricated compressor, it will stick more moist particles. In short, regardless of the choice of oil-free compressors and oil-lubricated compressors, efficient purification processes are a must.
