Disposable Vent Filter Assembly with Profile® Star Media

Protection from Airborne Contamination

The Disposable Vent Filter Assembly consists of a melt blown polypropylene filter element with a unique ‘star’ pleat construction, melt sealed into a self-contained polypropylene housing. This provides the user with a high level of security and protection, together with the handling advantages of a disposable filter assembly.

Aerosol qualification studies in dry gases showed that under the test conditions these filters have a particle removal efficiency of greater than 99.995% at 0.3 μm.

Each Disposable Vent Filter Assembly is individually identified by lot number for batch traceability.

 
Features Benefits
Fixed fiber matrix and highly stable structure
  • Secure contaminant entrapment without unloading due to
    pressure variations
  • No fiber migration and contamination of tank contents
  • Process reliability
Self-contained assembly
  • Easy handling
  • Easily fits onto tanks, totes and containers
Proprietary pleated polypropylene filter media with graded pore density
