ACT INTEGRATED SYSTEMS (ACT-ISD) is committed to improving the indoor environment of government and commercial buildings, hospitals, and laboratory facilities. We specialize in the design and fabrication of premium grade Custom Air Handling units and high efficiency air filtration systems for the removal of general airborne contaminants as well as toxic chemical, biological, and radiological (CBR) contaminants.

ACT-ISD offers an extensive line of custom factory-built air handling units, field-built air handling units, Enhanced Filtration units, and other high efficiency fan-powered air purification systems.


ACT-ISD began working with the US Army Corp of Engineers (USACOE) in 2000 to develop a new generation of chemical, biological and radiological (CBR) air handling systems. These special systems were named Enhanced Filtration Units (EFU) and they would be utilized to remove CBR contaminants from the outside air stream, properly condition the air and provide pressurization of building spaces for the protection of building occupants. The USACOE specifications for these new generation air handling systems required performance levels that were not typically available by most AHU manufacturers. The USACOE commissioning and factory and field testing requirements are some of the most demanding in existence and unattainable for most AHU manufacturers.

Today ACT-ISD is proud to be the leading manufacturer of these specialized CBR air handling units. ACT-ISD has manufactured and installed hundreds of specialized CBR air handling systems for the US Government and the USACOE.


BEFORE: Existing 50,000 CFM AHU

AFTER: New ACT Field Built Unit

The existing unit was 45 years old and had surpassed its useful service life. ACT installed this 50,000 CFM, field erected air handling unit at the US Army Adelphi Research Laboratory. The new ACT unit includes our 3” foam injected 100% thermal break R-20 casing, aluminum interior & exterior liners, minimum O/A combination damper AFS, air blender, MERV-15 filters, humidifier, hot and chilled water coils and dual direct drive fans. Final on-site testing showed less than .5% air leakage at 10” wg.

Don’t compromise quality. Our custom designed Air Handling Units offer efficiency & performance. You can reach us by phone at 703-547-1680, or click here to contact us online.
