WSO

WSO Mist Collector

Versatile Collector for Water, Smoke or Oil Mist

The Donaldson Torit^® WSO mist collector is the only collector that filters three types of mist (water, smoke, oil) in one collector – simply by changing the mist filter.

The Donaldson Torit^® WSO mist collector system filters water, smoke and oil via Synteq™ XP draining technology resulting in lower pressure drop and longer filter life.

Donaldson WSO Mist Collector

The versatile Donaldson Torit^® WSO Mist Collector provides three filter solutions for water-soluble coolant, straight oil, and the most challenging, oily smoke. The WSO uses revolutionary Synteq™ XP Media Technology engineered for superior draining, resulting in lower pressure drop and longer filter life.

The WSO can be modified with a simple filter change, leading to leaner operation, cost savings and cleaner plant air.

Oblong Cartridges Outperform Traditional Filters

Cross-Flow Design

Cross-flow filter design for better drainage means longer filter life. Dirty air flows horizontally through the walls of the WSO filter, perpendicular to drainage of collected and coalesced mist. This design promotes optimum drainage, which extends filter life and returns collected coolant for re-use. Conventional mist collectors have an upflow design impeding drainage and causing short filter life.

Advanced Filter Media for Mist

Proprietary Synteq XP Media Technology is a revolutionary new media for mist collection that provides high efficiency, low operating pressure drop, and long filter life when compared to traditional media.

FAQ

What Are the Advantages of Synteq XP Media?

Proprietary Synteq XP Media is engineered with a blend of small and large fibers with a resin-free bonding system. The result is superior performance and longer filter life in the most challenging applications.

What Size Are Mist Droplets/Particles?

Mist can generally be defined as a liquid droplet 20 microns in diameter or smaller. Oil-based fluids typically produce mist droplets that range from 0.5 microns to 10 microns. A smoke droplet is typically smaller, from 0.07 microns to 1 micron, and is a solid or liquid aerosol.

What Determines the Performance of a Mist Collector?

A mist collector can be characterized by pressure drop, efficiency, and flow rate. Pressure drops affects the energy required to pull the airflow through the system. The efficiency of the system determines how clean the air will be as it leaves the collector and flow rate determines how much air will be cleaned.
