Product Introduction

This mobile configuration uses rear intake and forward HEPA discharge to recirculate air continuously within the occupied room. The integrated fan-filter module measures 48 x 24 x 13.7 in and supplies up to 1100 CFM from a 120 V connection. A 304 stainless housing supports wipe-down, while published sound values of 45 dBA at 90 FPM and 58 dBA at maximum flow help users select an appropriate operating point near people.

Key Features

In-room recirculation

Air returns through the rear and exits through the forward HEPA face without requiring an exhaust duct.

Adjustable high-volume module

The 1100 CFM upper duty supports temporary recovery or supplemental filtration in occupied spaces.

Published acoustic reference

The 45 dBA value at 90 FPM provides a lower-noise baseline distinct from the 58 dBA maximum-flow condition.

Applications

Suitable for laboratories, treatment rooms, clean production support spaces and temporary work zones needing supplemental HEPA recirculation. The cabinet should be positioned so the rear intake remains open and the forward supply is not blocked by furniture or partitions.

Solutions for Your Application

A temporary room needs supplemental particle control without building an exhaust route.Use the rear-intake recirculating arrangement to filter and return air within the same space.

Maximum fan output may be disruptive close to staff.Begin near the 90 FPM acoustic reference and increase airflow only after checking room recovery and noise.

Available Options

Confirm HEPA or compatible higher-efficiency filter selection, fan control, cord arrangement, wheel locks and handle layout. Placement and duty should be planned around the room circulation path.
