Type DD
For Engines • Compressors • Industrial Ventilation

Airsan Type DD filters are heavy-duty, reusable pleated filters designed for engines, compressors, and general industrial ventilation systems operating in non-corrosive environments. These durable, cost-effective filters offer higher filtration efficiency than standard metal intake filters while maintaining long service life and low maintenance requirements.

Engineered for Long-Life Industrial Filtration

Type DD filters are constructed to deliver dependable performance in demanding applications without the need for full all-metal construction.

Key Features

  • Galvanized steel frame for mechanical strength
  • Long-lasting polyester media for enhanced particulate capture
  • Expanded metal facepieces (front and back) to prevent media shifting
  • Washable and renewable design, supporting years of service
  • Low-cost routine maintenance compared to disposable alternatives

These filters provide an excellent balance of filtration efficiency, durability, and value.

Ideal Applications
