Produkteinführung

This four-foot system adds redundant final filtration by placing two HEPA filters in series. Both filters can be independently scanned, and bag-in/bag-out service reduces direct contact with contaminated filters. The wider work area supports non-sterile hazardous-drug or potent-powder compounding that needs more staging space than the compact single-filter unit.

Key Features

Redundant filtration

Two series filters provide a second capture stage before air returns to the room.

Independent filter scanning

Each HEPA stage can be checked separately to support system verification.

Contained filter removal

BIBO hardware reduces exposure during replacement of loaded filters.

Applications

For non-sterile hazardous-drug and potent-powder compounding where double HEPA room recirculation is accepted by the facility's containment assessment. Procedures must cover BIBO filter changes.

Solutions for Your Application

A single HEPA stage does not provide the desired filtration redundancy.Use two independently scannable filters in series.

Removing a contaminated filter exposes maintenance staff.Use the bag-in/bag-out system and the site's controlled change procedure.

Verfügbare Optionen

Configure sash, work surface, airflow monitoring, electrical supply and BIBO accessories. Compound assessment determines whether recirculation is appropriate.
