3nine
What is 3nine?
3nine is a Swedish industrial company specializing in the development of indoor air purification solutions, particularly for the needs of the machining industry. The company's solutions are used in environments where machining generates oil mist, emulsion mist, and fine particles. 3nine’s systems are designed to improve the shop floor work environment, occupational safety, and air quality, all with minimal maintenance requirements.
The company’s core technology is based on a lamella separator, which allows for a very high separation rate in a compact structure. This makes the solutions suitable for both standalone CNC machines and larger shop environments.
3nine Lamella Separator Technology
The lamella separator technology used by 3nine is based on a principle that is over a hundred years old, which the company has further developed to meet the demands of modern machining. This technology relies on mechanical separation—removing oil mist and other aerosols from the air stream without traditional fiber or disposable filters.
The lamella separator can remove up to 99.9% of particles down to about one micron in size. This level of efficiency is especially important in shops that use cutting fluids, straight oils, and high spindle speeds. The mechanical separation reduces maintenance needs and makes the system highly durable.
3nine in Workshop Air Quality Management
In workshops and machine shops, indoor air quality directly affects workplace safety, machine condition, and production continuity. 3nine oil mist separators are typically installed directly on top of or next to the machine tool, reducing the need for separate and lengthy ductwork.
These solutions are ideal for CNC lathes, machining centers, and other chip-producing machines where oil and emulsion mists are generated. The separated liquid is returned to the machine for reuse, supporting cutting fluid management and reducing waste.
3nine GREEN LINE and BLUE LINE Product Series
3nine’s product range is mainly divided into the GREEN LINE and BLUE LINE series. GREEN LINE is designed as a versatile solution for a variety of machining processes—including demanding applications such as cast iron machining and grinding. The series is suitable for both emulsion- and oil-based processes.
BLUE LINE is a more traditional product range that covers a wide range of airflow needs and is especially suitable for local air purification of individual machine tools. Both series are characterized by a compact design, low maintenance requirements, and long service life in industrial shop environments.
3nine Ownership and Environmental Perspective
Since 2022, 3nine has been primarily owned by the Nordic investment company Alder. Alder focuses on long-term ownership of businesses that support environmentally sustainable solutions. 3nine’s operations help the manufacturing industry meet environmental requirements by improving indoor air quality and reducing the need for consumable filters.
The core philosophy of the company is that clean air should be accessible to everyone working in machine shops. This is reflected in the development of their solutions, which combine technical functionality, low operating costs, and environmental responsibility.
Summary
3nine is a Swedish manufacturer of indoor air purification solutions for the machining industry, offering an efficient and maintenance-free way to control oil mist in workshops through its lamella separator technology. Their solutions improve the work environment, reduce maintenance needs, and support cutting fluid management. 3nine's products are especially suited for CNC machining and demanding industrial settings, where clean indoor air is essential for safe and efficient production.
