What We Do

Equipment and Solutions Built Around Your Application

Mainstream Fluid & Air designs and supplies HVAC equipment for commercial and industrial facilities — from new air-handling projects to retrofits of existing mechanical systems. Our product range covers fan arrays, ventilation equipment, replacement coils, cooling tower fan systems, and the controls that tie them together.

Custom Fan Arrays

Modular fan array systems engineered as airflow solutions for commercial and industrial air-handling applications, suitable for new equipment and retrofit projects. Configurations can be developed around project airflow, static pressure, dimensional, access, motor, and control requirements.

Air Handling & Ventilation

Fan and ventilation solutions for commercial and industrial air-handling applications, including plenum fan and axial fan configurations selected to match the airflow and installation requirements of the project.

Replacement Heating & Cooling Coils

Replacement coils for existing HVAC and air-handling equipment, supporting heating, cooling, and equipment-replacement applications across commercial and industrial systems.

Cooling Tower Fan Systems

Engineered fan systems for cooling tower applications and retrofit projects. Modular fan configurations can support serviceability, system flexibility, controllability, and redundancy where applicable to the design.

HVAC Controls

HVAC fan systems can incorporate control solutions for coordinated fan operation, speed control, and system monitoring, with integration into building automation applications where supported by the selected equipment.

Retrofit & Replacement Projects

Support for modernizing existing air-handling units and cooling tower equipment, with equipment developed around existing dimensions, access constraints, and facility operating conditions.

Engineered Around the Application

Solutions Developed Around Project Requirements

Commercial and industrial HVAC projects rarely look identical. Existing equipment dimensions, airflow and static pressure requirements, access restrictions, electrical requirements, control needs, and facility-specific operating conditions all shape the right solution.

Rather than treating every project as an off-the-shelf application, Mainstream Fluid & Air works from the specifics of your facility and equipment — whether that means a full air-handling replacement, a targeted coil swap, or a cooling tower fan retrofit.
