Different brands of low-pressure screw compressors have different prices. Here, take Granklin air compressor as an example. A 7.5kw small oil-filled air compressor is about 20,000. This belongs to the middle and high grade, and other brands are either high or low.
The price of oil-free air compressor is higher than that of oil-free air compressor. At present, the industry is upgrading. The use of oil-free air compressor is better for food and other enterprises. Food safety inspection is very strict. Eliminating oil from the manufacturing source is one of the application scenarios of granklin oil-free air compressor.
of course, there are smaller, 4kw, or piston machines below 7.5kw.
Piston machines have been slowly eliminated by the market. Although Granklin Group also has piston machines, I have never asked their prices here, nor have I bought piston machines, so I won't talk about them here.
In addition, the piston machine is definitely not silent. Generally, the noise of the screw air compressor is about 60 minutes, and the piston machine is far greater than this.
Air compressor, namely air compressor, is the equipment that uses electric energy to do work and compress air to generate high pressure to drive other mechanical devices to run. It is the core component of the air source device. Air compressor according to its working principle can be divided into: volume type, power type. positive displacement compressor
In the operation of most compressors, there are complex problems such as low efficiency, unsatisfactory equipment operation parameter setting, equipment mismatch, large pressure loss of pipe network, unscientific early selection, system leakage, artificial demand, incorrect use and inappropriate system control, etc.
The first guarantee is usually 500 hours, that is, the first maintenance of the machine running-in. The first guarantee is relatively simple. It is good to replace the oil and filter. After the maintenance is generally about 2500-3000 hours, but also related to the air compressor site environment, if the site environment
The competitiveness of domestic air compressors in the global market has become stronger and stronger in recent years, thanks to the upgrading of the entire domestic industry. In the past like to buy imported air compressor, different times more and more enterprises began to choose to buy domestic air compressor.
There are always people in the market asking whether the oil-free air compressor is real. Shanghai granklin group has been engaged in water lubricated oil-free air compressor for many years, and the oil-free screw air compressor we produce is sold all over the country. In petrochemical, food processing, medical equipment, electronic equipment
Oil-free air compressor three filters mainly include: oil-free air filter, oil-free oil filter, oil-free oil and gas separator. The method of replacing each filter element is slightly different, and we will talk about it separately. The water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
In the textile industry, air-jet looms require dry and oil-free compressed air. In the production process, the thin nozzle blows compressed air onto the wire harness to form a vortex, which gives the yarn shape, elasticity and elasticity from the surface. The pure compressed air provided by the oil-free air compressor can ensure the quality of the finished fabric. At the same time, the air-jet loom also requires the quality of compressed air:
View detailsTwenty-first Century air compressor market competition is fierce, consumers in the purchase of products, often the machine quality and price included in the purchase standard. Therefore, this article will be common in the market a variety of labeling methods to make a description, in order to protect the interests of consumers to do a force.
The water-lubricated air compressor produced by Shanghai Granklin Group is a screw-type air compressor, which is very consistent with the characteristics of stable gas supply and oil-free gas. In terms of energy saving, we can also choose water-lubricated permanent magnet variable frequency air compressor, which fully meets the needs of both oil-free and environmental protection and energy saving.

This belongs to the middle and high grade, and other brands are either high or low. Of course, there are smaller, 4kw, or piston machines below 7.5kw.
