Greenheck released fan filter diffusers to its line of healthcare, laboratory, and cleanroom (HLC) air distribution products.
Fan filter diffusers are unidirectional diffusers with integrated EC motors and high-efficiency filters. They provide ultra-clean air that is necessary in critical applications or retrofit applications where additional power is needed to overcome filter pressure drop.
- Model HLC-FPS is a self-contained fan filter supply diffuser with airflow rates up to 1200 cubic feet per minute (cfm) to meet United States Pharmacopeia (USP) 797 and 800 air change requirements. The HLC-FPS connects directly to system ductwork and can be installed in a ceiling grid or hard ceiling.
- Model HLC-FPR is a ceiling or wall-mounted fan filter return diffuser that creates a negative pressure environment drawing air up and out of a room, removing airborne contaminants via the unit’s gel-seal high-efficiency filter, and discharging clean air.
- Model HLC-FPI is a ducted inline fan filter unit designed to continuously filter the air passing through the unit and remove a wide range of airborne contaminants, making it ideal for schools, office buildings, and other commercial indoor environments.
- Model HLC-FPC is a fan filter mobile cart available in both recirculation and return/exhaust configurations that can act as an in-room air purification device.
The Greenheck fan filter diffusers provide quiet, energy-efficient operation, and can be specified with HEPA or ULPA filters, or supplementary MERV-rated pre-filters depending on the application. Ceiling-mounted, inline, and portable models are also available.
