Description
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 |
