3 Nine

Oil mist eliminators

3nine is a Swedish company that develops solutions for the purification of processed air. Our revolutionary technology is based on disc stack separation, which resolves in an extremely high degree of purification in a very compact format and requires a minimum of maintenance.

Liquid-to-gas separation technology was invented over 100 years ago. Since 2002, 3nine has been awarded over 100 patents, making us a worldwide leader with over 40% of all the patents globally relating to this technology.

Our goal was to bring oil mist elimination to a new level, develop products that were well adapted for all applications using either oil or coolant and to simplify the monitoring of the products through visual and digital communication. The new series, called the GREEN LINE, is based on Multi-Rotor and Counter Current Technologies. Multi-Rotor technology facilitates scalability which allows for the many airflow requirements and Counter Current Technology allows each unit to work with all machining applications using either oil or coolant.

The Green Line

The GREEN LINE series of units separate 100% of all fluid particles down to 1 μm, 91% down to 0.9 μm and 82% down to 0.75 μm. In order to capture the finer particles that are <1μm, 3nine uses a HEPA filter (H13) to ultimately clean the air to 99.97%. With most of the particles separated in the disc stack, only  1% of the particles are collected in the HEPA filter.

The Blue Line

They produce 500-2500m3/h and can handle machine tool cabins up to 20m3 with 1 unit.

The BLUE LINE series of units separate 99.9% of all fluid particles down to 1μm, 91% down to 0.9μm and 82% down to 0.75μm. In order to capture the finer particles that are <1μm, 3nine uses a HEPA filter (H13) to ultimately clean the air to 99.95%. With most of the particles separated in the disc stack, only 1% of the particles are collected in the HEPA filter.

Oil mist exposure can cause severe health issues for the operator. If not handled properly, the oil mist will coat the surfaces in the shop, causing risk of injuries by slippery surfaces, an increased need of cleaning and damages on electrical devices. With an oil mist separator from 3nine, this will not be a problem. The air coming out of a BLUE LINE oil mist eliminator is so clean that it can be recycled right back into the workshop and guarantees an optimal working environment for the operator.
