Product Introduction

The shortest narrow reverse-flow unit uses a 15.7 x 23.63 in footprint and a 16.125 in height. Air is drawn from the controlled space through a MERV 7 prefilter and 99.99% HEPA stage, while a dust collector pan supports room-side service. Its 2.2 ft² active face is tailored to small isolation or maintenance enclosures.

Key Features

Compact exhaust pickup

The short chassis fits negative-pressure ceiling positions where a conventional 2 x 2 ft unit is too wide.

Contained room-side maintenance

The collector pan and room-side access reduce reliance on an overhead service space.

Adjustable reverse flow

A variable-speed 1/4 hp PSC assembly allows the exhaust contribution to be balanced.

Applications

Designed for compact isolation rooms, cleanroom renovation enclosures and localized equipment-repair containment. The 16 in width is particularly useful between congested ceiling services.

Solutions for Your Application

A standard exhaust module cannot fit the narrow ceiling opening.Use the 15.7 in wide cabinet and keep the room-side filter face accessible.

Dust may fall during filter service.Retain the integral collection pan and follow a controlled room-side removal sequence.

Available Options

Choose ceiling frame, duct adapter, filter alarm, suspension hardware and control panel. Balance the variable-speed exhaust against replacement air.
