Fan filter diffuser line

Greenheck fan filter diffusers are unidirectional diffusers with integrated EC motors and high-efficiency filters that provide ultra-clean air necessary in critical applications or retrofit applications where additional power is needed to overcome filter pressure drop. Ceiling-mounted, inline and portable models are available. Model HLC-FPS is a self-contained fan filter supply diffuser with industry-leading airflow rates up to 1200 cfm to meet USP 797 and 800 air change requirements. The HLC-FPS connects directly to system ductwork and is simple to install 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. 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 upon the application.

Healthcare, Laboratory and Cleanroom Air Distribution Products

Greenheck’s new line of healthcare, laboratory, and cleanroom (HLC) air distribution products are designed, engineered, and tested to meet or exceed today’s critical environment standards for performance and energy efficiency. This product line includes Laminar Flow Diffusers, Radial Flow Diffusers, and Surgical Air Curtains. Laminar flow diffusers are engineered to provide a vertical projection of low-velocity supply air, introducing clean supply air without the entrainment of airborne particulate in the space due to its low velocity. These diffusers play a critical role in maintaining an aseptic environment below the diffusers in operating rooms, patient isolation rooms, pharmacies, and cleanrooms. Radial flow diffusers provide an effective method of air distribution in laboratory and patient isolation room applications where a high volume of air is required.
