Oil-free air compressor, which is better

Good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor.

But the oil-free air compressor is much more expensive and the maintenance cost is higher. If it is used for purging, machining, manufacturing and power use, it is possible to choose an air compressor with oil and micro oil.

Such as spraying, steel, electricity, hardware, mining, ceramics, textiles, machinery, etc. are widely used.

The distinction between oil and no oil The oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil machine is 0.01ppm. Therefore, this oil content is used to distinguish the oil and no oil in the air compressor.

The advantages are as follows:

because of the high viscosity of the lubricating oil, the oil removal equipment cannot be completely removed, so that the oil-free air compressor compressed gas does not contain oil.

2. Water removal equipment such as refrigerated dryer, heat-free regeneration dryer and micro-heat regeneration dryer lose water removal function due to oil in compressed air. The clean oil-free gas compressed by the full oil-free compressor fully protects the water removal equipment and reduces the additional capital occupation caused by the maintenance of the water removal equipment.

3. Using an all-oil-free air compressor to provide compressed gas to the outside will not greatly reduce the motor load due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect; A good quality three-stage oil remover will produce a pressure loss of 1 to 1.2kg during use. A 7.5KW air compressor will pay an extra 600W of power loss for every 1kg of pressure increase, and 6 degrees of electricity for every day of work (10 hours, for example), this will be a long-term intangible expense.

4. The use of oil air compressor greatly wastes lubricating oil. Taking a 7.5KW high-quality oil air compressor as an example, it consumes a minimum of 5kg of lubricating oil per month, and will pay an extra 60kg of lubricating oil use cost in a year. At the same time, in order to remove the oil in the compressed gas, it is necessary to use an efficient oil filter and replace the filter core many times, which is also a great expense.
