FAN FILTER UNIT

PRODUCT OVERVIEW

Introduction

Price Fan Filter Units (FFU) are ceiling module diffusers consisting of a fan/motor assembly and Roomside Removable (RSR), or
Bench Top Replaceable (BTR) filters. The module is designed to provide unidirectional vertical airflow of filtered, clean air over a
cleanroom space.

Fan Filter Units (FFU) models will have three (3) stickers located on the back of the plenum. For ease of troubleshooting assistance,
replacement parts, and general factory assistance, it is recommended that the order number, and model line string be used as
reference. This information can be found on the Factory Label.
