For Heating • Cooling • Ventilation • Demisting
Airsan Type W filters are engineered for applications requiring high airflow velocity, durable construction, and long-term performance in demanding environments. Used extensively in turbine generators, power plants, wind turbines, offshore oil rigs, military submarines, and surface vessels, the Type W is one of Airsan’s most proven permanent metal filter designs.
Engineered for High-Velocity Airflow
Type W filters are viscous-impingement metal filters, designed to capture particulates by combining adhesive media with high-impact airflow. This makes them ideal for:
- Heating and cooling systems
- Ventilation equipment
- High-velocity air handling units
- Demisting and moisture removal
- Pre-filter stages in power and industrial systems
- Air intake or post-coil placement
Whether installed upstream or downstream in the airstream, the Type W delivers reliable, consistent filtration in both light-duty and severe-duty applications.
Built for Durability & Performance
Airsan Type W filters are constructed to withstand harsh industrial environments while maintaining airflow and filter integrity.
Standard Construction
- Galvanized steel frame and media
- Available in 2” or 4” nominal thickness
- Optional custom thicknesses for non-standard designs
- Vero Crimp/Media Design
- Internal support rods
Key Benefits
- Performs in high airflow velocity applications
- Excellent for demisting and moisture control
- Durable permanent design reduces replacement costs
- Suitable for severe-duty industrial and marine environments
- Fully customizable to system specifications
Optional Materials for Specialized Applications
Depending on environmental or system requirements, Type W filters can also be manufactured using:
- Aluminum
- Stainless steel
- Bronze
- Other specialty metals upon request
These material options make Type W filters ideally suited for corrosive, high-moisture, or marine environments.
Viro-Crimped Media
Our patented Viro-Crimped media is constructed of horizontal wire screen cloth to provide a large filtering area while eliminating direct air passages through the filter media. Media edges are hemmed for worker safety, and reinforcing rods are centered through the filter to prevent media shifting for consistent structural integrity.
