Product Introduction

This 30 x 50.5 in configuration is the smallest published size in the suspended vertical-flow family. It can hang from the ceiling or mount on a support frame above a compact instrument. The filter, blower and optional light are serviceable from the front, and the prefilter can be placed on top or front when overhead access is limited.

Key Features

Compact local coverage

The smallest family footprint targets a defined instrument or short process area without filtering a full room.

No-plenum service access

Front access to the filter and blower supports maintenance where the ceiling space cannot be entered.

Flexible prefilter position

Top or front placement lets the intake remain serviceable around suspension rods and nearby utilities.

Applications

For localized clean-air protection above compact semiconductor, optics or medical-device equipment when ceiling-plenum access is unavailable. Suspension points and the protected footprint should be coordinated with the machine envelope.

Solutions for Your Application

A standard ceiling-grid FFU cannot be serviced from above the equipment.Use the front-service suspended module and keep its access panel clear.

A large hood wastes filtered airflow around a compact process.Select the 30 x 50.5 in footprint and align it directly over the critical area.

Available Options

Choose painted or stainless housing, front/top prefilter, light diffuser, power cord and 220 V 50 Hz supply. Suspension hardware and support frame can be adapted to the equipment layout.
