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.
Greenheck’s XG-TH-500 Series Air Terminal Units (ATU) are zone-level air distribution devices that regulate airflow for maximum occupant comfort in variable or constant volume applications. The single-duct XG-TH-500 features a galvanized steel casing mechanically sealed for low leakage construction along with a round inlet damper, an inlet flow sensor, and a rectangular outlet. Cooling only, hot water coil, and electric heat configurations can be specified.
Greenheck’s new KSQ mixed flow roof supply fan provides energy-efficient building supply or untempered make-up air in applications where heating and cooling are not required. Model KSQ is available in direct drive sizes 7 through 33 with performance up to 16,750 cfm and 2.75 in. wg in multiple configurations including horizontal or bottom intake and horizontal or bottom discharge.
Greenheck has redesigned model USF single-width centrifugal utility sets in sizes 4 to 24 to incorporate more features and options. The USF now offers expanded direct drive selections with Vari-Green motors up to 10 hp. Factory-mounted or ship-loose controls with VFDs are now available with belt or direct drive motor configurations up to 30 hp.
Greenheck's BTDR-50 is a cable-operated radial blade balancing damper, also known as a bowtie damper, that is designed for easy airflow adjustment at an air outlet or plenum neck. The BTDR-50 is available in steel in 6-, 8-, 10-, 12- and 15-in. diameters, with pressure capacity up to 1 in.
Greenheck’s new Modular Open Array, model MOA, provides a turnkey retrofit package that delivers certified performance, communication, and controllability. The MOA configurable fan array features lightweight, easy-to-assemble components that ship to the job site knocked down for field installation. UL power and controls packages are available and array panels arrive prewired for quick and easy installation saving time at the jobsite.
Greenheck’s extensive product line continues to grow with the addition of model DDF, a directional destratification fan that improves comfort and reduces energy costs by efficiently mixing air from floor to ceiling for uniform temperature distribution. The high-performance direct drive model DDF is available in three sizes and performance levels: a 10-inch diameter for ceilings up to 25 feet, a 12-inch diameter for ceilings up to 45 feet, and a 14-inch diameter for ceilings up to 60 feet. Model DDF features an aerodynamically optimized housing for maximum airflow, throw distance, and coverage area and includes Greenheck’s Vari-Green electronically commutated (EC) motor and controls technology for maximum efficiency and controllability.
The AMPLIFY DM-3 is a small-diameter architectural overhead fan that boosts occupant comfort while enhancing the interior design of commercial and institutional building spaces. Featuring curved polymer airfoils designed to maximize airflow, improve efficiency, and optimize coverage area, the DM-3 is available in a 5-foot diameter with airflow up to 7,113 cfm and cooling effect up to 7oF/4oC. The DM-3’s lightweight, direct drive motor is up to 20% more efficient and 10 dBA quieter than traditional motors.
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.
