How to choose an oil-free and oil-free air compressor

The difference between oil-free air compressor and oil-free air compressor is: different materials, different final discharge of gas, and different life.

Different 1. materials

1. Oil air compressor: The material of oil air compressor itself contains oily substances, which will pollute the terminal equipment,

2, oil-free air compressor: oil-free air compressor itself does not contain oily substances, to avoid the oil machine on the terminal equipment pollution. (Grantklin oil-free air compressor)

2. the final exhaust gas is different

1, oil air compressor: oil air compressor with oil lubrication, so the final discharge of the gas containing oil.

2. Oil-free air compressor: The oil-free air compressor is lubricated with resin material, so the final discharged gas does not contain oil.

3. life is different

1. Oil air compressor: There is no heat-resistant piston in the oil air compressor, and the sealed grease is easy to lose, resulting in dry grinding and damage to the bearing, and the oil air compressor has a short service life.

2. Oil-free air compressor: Oil-free air compressor uses a heat-resistant piston, so that the bearing grease is no longer lost by high temperature conduction and radiation, thus greatly prolonging the life of the oil-free air compressor.

Personally, I don't think that air compression equipment is good or bad, and it must be determined according to the use environment of individuals or enterprises, such as pressure, gas production, use requirements, etc.

The traditional micro-oil screw air compressor for general industrial production is a good choice. However, oil-free equipment for enterprises with high requirements for air purity quality in characteristic industries such as food processing and medical equipment precision electronics is definitely the first choice. At present, only dry oil-free and oil-free water lubrication equipment for screw air compressors of oil-free air compression equipment can be made, and only dry oil-free and oil-free water lubrication equipment are common equipment in the market.

The former has high technical standards and higher maintenance costs. There are almost no manufacturers in China. Water lubrication equipment is completely different. It is a model of low-cost operation. The price of the equipment is not high, which is about twice the price of traditional equipment. However, there are several issues to consider when choosing oil-free water lubrication equipment. The first is your area, generally, when purchasing the equipment in areas that will freeze in winter, it is necessary to consider the problem of water freezing in winter.

Granklin's oil-free screw air compressor is relatively stable. Many factories on the market purchase their things. You can learn about it.
