Product Introduction

The U15 model retains dedicated active downflow but changes the supply filter class from the H14 configuration. It is intended where the user's contamination-control strategy explicitly selects U15 media and can accommodate the associated fan duty, filter cost and replacement plan rather than treating the higher grade as a universal requirement.

Key Features

Higher-grade supply media

U15 filters address specifications that call for ULPA rather than the H14 standard arrangement.

Fan-filter coordination

Dedicated airflow control can be sized around the pressure drop of the selected filter bank.

Continuous condition visibility

Pressure and airflow monitoring help operators recognize departures from the configured operating state.

Technical Parameters

RABS Type	Active open restricted access barrier
Process Zone	ISO 5 / Grade A
Background Room	Typically ISO 7 / Grade B
Nominal Downflow	0.45 m/s ±20%
Supply Filters	U15 ULPA
Fan System	Dedicated actively controlled modules
Filter Plenum	Negative-pressure plenum arrangement
Monitoring	Differential pressure, airflow and door state
Barrier Construction	Stainless frame with safety-glass panels
Customization	ULPA bank size, fan duty, access configuration, transfer ports and machine penetrations can be matched to the intended aseptic process.

Applications

Sensitive aseptic filling, open-container interventions and critical component zones where the facility specification calls for active U15-filtered protection.

Solutions for Your Application

A procurement specification requires U15 media rather than standard H14 supply filtration.Select the U15 filter bank and size the active fan modules for its operating resistance.

The higher-grade filters may change maintenance access and replacement cost.Define front or technical-area service access and filter-bank zoning during equipment layout review.

Available Options

Filter-bank segmentation, redundant fans, reduced-flow mode, RTP connections, PLC monitoring, door alarms and service-side access may be configured.
