Applications: 

1.Wastewater treatment:

In many areas of environmental protection and industrial production, blower products that provide low-pressure air are required. In the field of environmental protection, rod blowers are used for both waste water discharge and air discharge. Water is vital to the never-ending life of our planet; it requires purification and recycling of waste water. Reliability, flexibility, and energy efficiency are vital factors; screw blowers provide all of these features. It is a solid, flexible variable that adapts to a wide range of air speed driven fan flow requirements. Its high level of energy efficiency limits energy costs, which typically account for 70% of total costs. Operating costs of water treatment plants

Application 2: For pneumatic conveying, you need a heavy-duty blower that can handle blockages in powder conveyance and true variable system requirements. The screw blower is a powerful blower that will serve you for years with minimal downtime. Pneumatic conveying products are expensive. Energy costs account for about 80% of the fan's life cycle cost. Therefore, high energy efficiency levels and low maintenance costs of the fans will reduce the cost of the final product.

Application 3: The textile industry runs continuously 24 hours a day, 7 days, but changes the process mode. The screw blower is easy to handle the demand for adjusting the air volume to affect whether the loom is in the most energy-saving state. It takes full advantage of the high efficiency of some permanent magnet motors. The ceiling of the screw blower is carefully designed to ensure a low noise level.

Application 4: Fermentation, desulfurization and denitration, air knife, texturing
Applications in industrial engineering such as bioengineering, pharmaceuticals, cement, steel, power generation, food processing, and textiles will also use oil-free screw blowers.Efficient oil-free collapsing fans can be applied in many industrial fields, thus providing national The economic unit's output value reduction makes its important contribution.

Features:

1.High process uptime and low life cycle costs
Energy costs can add up to 80% of the turbine life cycle cost. That's why we continue to develop new fan models that consume the lowest energy levels. Dehaha oil-free screw blowers are driven by our internally developed liquid. Cooling permanent magnet motors. Combined with a VSD inverter, this successful energy-saving variable-speed drive solution operates trouble-free in the harshest environments.
Comparison of Oil-free Screw Blower and Roots Blower
At present, Roots blowers are still widely used in various industries. In the past, its simple and reliable design solved the process application problems in various fields and made its application contribution to economic development. However, its inherent characteristics of high noise and high energy consumption are incompatible with the environment of energy conservation and environmental protection. Oil-free screw technology brings efficient and environmentally friendly blower products, which will gradually replace the outdated technology of Roots blowers.

As shown in the figure, the blue area is a comparison of the functional consumption of the screw blower and the roots blower.

In practice, the higher the pressure required by the equipment, the more significant the energy saving effect of the screw blower; at 0.5 bar pressure, the energy saving reaches 25%, and at 0.8 bar pressure, the energy saving can reach 35%.

Oil free blower save energy35%

2,The most energy efficient variable speed drive fan on the market
Take the next step in developing energy-efficient and low-voltage solutions. Comprehensive introduction of permanent magnet motors with the best energy saving effect Variable speed drive oil-free screw fans on the market.
3,Durable and reliable design
For us, every design choice is made by a reliable and durable solution. Our permanent magnet motor housing is expected to have a liquid-cooled jacket to keep it in
The oil-free screw compressor technology that has been fully verified by the market is applied to the field of blowers with lower pressure. The technology is mature without any pressure at all. The design and manufacturing experience of oil-free screw compressors has also made oil-free screw blowers with stable and reliable quality. Screw fans derived from oil-free screw compression technology have excellent performance and attractiveness.
Any case. Ensure that the proper amount of cooling oil is delivered to the bearings and gears. Ensure process uptime.
4,Ensure process quality and process uptime
Choose the highest guaranteed oil-free air delivery with 100% pure level 0 certification. Fully operable, the intelligent monitoring system allows you to inform the health status of the machine online and proactively propose services.
