Filter Fan Unit (FFU) Installation, Replacement & Maintenance
Flexible and affordable filter fan unit provide a versatile, energy-efficient alternative to traditional HVAC systems, offering the portability and advanced control needed to maintain precise cleanliness in any cleanroom configuration.
Cost-effective and portable filtration
Versatile and Efficient Filter Fan Unit Solutions
Filter Fan Unit (FFU’s) are a cost-effective alternative to pressurized plenums and ducted air-handler filter networks.
These units can be deployed in a wide variety of configurations including Low profile, 2’x2’ through 4’x4’ sizes and a variety of filtration and communication strategies/protocols.
Because these units provide lower energy consumption and offer extreme portability and retrofit ability, many end users are replacing their larger, inefficient HVAC equipment configurations with this option.
One Source Environmental offers our own branded Filter Fan Unit but have worked with a wide variety of competitive units. We are happy to discuss Commissioning, Control, installation, replacement or maintenance regardless of the Manufacturer or Model.

Integrated control and maintenance
Filter Fan Unit (FFU) PLC Control Systems, Commissioning & Control System Integration
Through our partnership with Global Cleanroom Solutions (GCS) we offer PLC (Programmable Logic Controller) based FFU Control Systems that allow Clients to visualize and control the FFU’s providing Filtered Supply Air to their Cleanrooms.
These systems allow controllability, visibility and alarming features that are important to the daily operation of these manufacturing environments. We typically use Allen Bradley or Siemens systems with Modbus/TPC interface to the Facility Maintenance Control System (FMCS) to control FFU’s within defined groups across a Local Area Network (LAN).
FFU Control Systems are a very affordable and extremely configurable solution for the control of larger FFU networks.
