Affordable Oil Mist Containment for Any Manufacturing Environment

Engineered to work in the most demanding manufacturing environments, the Duroair OMW series of oil mist filtration systems regularly outperforms most centrifugal collectors with less maintenance and at a significantly lower capital investment.

For a safe, clean metalworking environment, pair OMW with:


OMW Series Filtration System

Unlike traditional oil mist collectors with overpriced centrifugal filters, cartridges, and electrostatic precipitators, the OMW’s streamlined multi-filtration process quickly and effectively separates solid particulates in oil and water and captures oil for reuse.

Duroair has completely reinvented the oil mist collection process for a more cost-effective containment solution to effectively improve health, safety, and productivity.

The OMW ambient capture solution:

  • Requires no ductwork, so it won’t interfere with overhead cranes or other obstructions that cause trouble for existing ventilation systems
  • Reduces noise levels with an integrated silencer by decreasing static pressure
  • Adjusts via Clarion® unit nozzles to create airflow patterns that work best in your facility

Technical Specifications

  • Equipped with four different CFM models and one-to-four-year filter life to handle high pressure fluids and smoke and mist
  • Requires no ladders for easy-access maintenance
  • Comes standard with VFD and fluid pump
  • Recycles expensive fluids with self draining and cleaning functionality
  • Traps oil and particles via the first wicking stage
  • Drains these particles down into the sump located below the filter at state of saturation
  • Pumps oil mist away for reuse or disposal
  • Filters out finer mist and smoke particles in second wicking stage
  • Captures the remaining smallest particulate down to 0.30 microns in third stage wicking
  • Discharges clean air from the top of the collector into the facility

Available OMW models:
  • OMW 800 with 800 Airflow CFM
  • OMW 2000 with 1500 Airflow CFM
  • OMW 3000 with 3000 Airflow CFM
  • OMW 6000 with 6000 Airflow CFM
