Product Detail

BOBAIR as a manufacturer of clean compressed air systems, providing high-clean, pure oil-free compressed air, leading the future direction of the air compressor industry, providing customers with high-quality products and the best user experience. The water-lubricated oil-free screw air compressor, as well as the unique all-stainless steel alloy air end and stainless steel system are well-known in the industry.

The air end has a stainless steel alloy rotor with the longest lifespan, and the rotor meshing pair is produced using patented technology of flying parts. The contact stress between the rotors is very small, thereby reducing internal leakage and rotor compounding.

During the working process of the rotor, do not spray the pure water between the rotors for cooling, so as to clean the air. Minimizing dust and heavy metal content. At the same time, the Z-shaped rotor and the pure water between the rotors will form a good water film seal, making the system efficiency reach more than 95%. Fully realize energy saving, oil-free compression system, no oil or waste oil treatment, able to extract the purest compressed air. The water-gas mixture compressed by the main machine enters the water-gas separation cylinder and is mechanically separated into compressed air and pure water. Because the system temperature is below 45 ℃, the moisture content of the compressed air is less than 80 g/m3.

The compressed air on the separation cylinder passes through the minimum pressure valve and enters the exhaust hole for discharge. The pure water at the bottom of the separation cylinder is passed through the filter to remove impurities and bacteria in the water. After cooling, the water enters the compressor air end again for the second compression cycle. The water-lubricated oil-free screw air compressor realizes automatic water change and reduces labor intensity.

Water-cooled plate heat exchangers are highly efficient and corrosion-resistant. The cloud network can realize 24-hour wireless interconnection monitoring of the network, remote communication of multiple machines, remote early warning machine alarms, and timely reminders of normal care and maintenance. Water-lubricated oil-free screw air compressor is an energy-saving, environmentally friendly and stable product among oil-free compressors.

It is widely used in various industries such as photovoltaic chemical industry, food, textile, mechanical electronics, medicine, and bioengineering.

Jiangxi Bobai has launched a completely new range of high efficiency, oil-free two-stage rotary screw compressors to further enhance its successful. These high output oil-free machines now cover a wide flow range from 6.0 to 40.0m3/min, the pressure range from 20bar to 40bar.

High-pressure compressed air is used for blowing bottles.
The pressure depends on the container’s design, wall thickness, blow speed, and so on. The bottles with thick walls, sharp edges, and special shapes need higher pressure. Generally, the stretch blow molding requires about 10~25bar for pre-blowing and about 40bar for the bottle-blowing process. The trend for PET bottle-blowing machines is to reduce the blow pressure as much as possible for energy saving.
The bottles should be cleaned with compressed air before filling the water, beverage, cooking oil and so on.
If the air is contaminated, it will influence the flavor and odor, causing health problems.

For screw type, the air is compressed to 7~8bar at the first screw compression stage, there is no need to cool and the air goes into the second stage screw air end, finally achieving 30~40bar air discharge directly without cooling. Rotation speed 3000r/min, zero loads. About 50℃, no heat waste, Ideal isothermal compression.
