MCOS is a filtration system designed to separate oil and smoke particles from the air in particularly heavy duty work conditions, using the principle of coalescence. Applications for this type of filtration are heavy duty mechanical processing.

The air flow passes through the multilayer fibreglass filter element at low speed, where the coalescence process takes place. By crossing the increasingly thick layers of filtering material, the microparticles of the pollutants are agglomerated, reaching macroscopic dimensions.

What is the coalescence principle? Coalescence is the physical phenomenon through which liquid droplets, gas bubbles or solid particles come together to form larger entities.

Unlike traditional static filters, the coalescence filter does not work exclusively based on clogging, as the particles reach a weight that causes them to fall by gravity into the collecting tank, significantly increasing the useful life of the filter. Once the filter element has been crossed, the air flow goes back to the next element at a low enough speed to avoid dragging the finest particles. To ensure a higher level of purification it is possible to install an additional absolute filtration stage (FFA),with an efficiency rating of 99.99%.

The collected oil particles are expelled through a drain pipe positioned on the back of the filter.
