Purpose: Pressurize a chamber (plenum) in an HVAC air handling unit (AHU), allowing air to be distributed directly from the cabinet into ductwork without the need for traditional, bulky scroll housings.
Applications: Commercial HVAC systems, cleanrooms, laboratories, data centers, hospitals and other spaces requiring quiet and efficient airflow delivery.
High-Efficiency Plenum Fans Engineered for Commercial HVAC Systems
The Model PLF plenum fan is specifically designed for fan array applications in commercial HVAC and air handling systems, delivering high airflow performance, energy efficiency, and installation flexibility. Featuring a lightweight aluminum airfoil wheel, the Model PLF reduces power consumption compared to traditional plenum fans while maintaining exceptional airflow capacity and static pressure performance.
Its advanced extruded aluminum airfoil blade design improves aerodynamic efficiency, reduces overall fan weight, and enhances acoustic performance for quieter operation in commercial and industrial environments. The result is a high-performance plenum fan solution optimized for modern air handling units (AHUs), retrofit projects, and custom fan array configurations.
EC Motor Compatible for Precision Airflow Control
The Model PLF fan platform fully supports EC motor technology for improved energy efficiency and intelligent airflow management. Integrated speed control through EC motors with built-in variable frequency drive (VFD) capability allows precise airflow adjustment without requiring additional external components.
Available in six wheel diameters and multiple wheel widths, the Model PLF allows engineers and system designers to fine-tune airflow performance for fan arrays and other commercial plenum fan applications requiring reliable, high-efficiency air movement.
Performance Specifications
Airflow Capacity: Up to 22,000 CFM
Static Pressure: Up to 12" SPWG
Lightweight Aluminum Airfoil Wheel Design
When airflow efficiency and system performance are critical, the EV aluminum airfoil wheel (Series CDAF) delivers exceptional results in commercial plenum fan and air handling applications. Engineered with eleven precision aluminum airfoil blades, the wheel improves airflow control, enhances aerodynamic performance, and supports higher overall HVAC system efficiency.
The lightweight aluminum construction reduces rotational mass while maintaining durability, making it an ideal solution for high-efficiency fan arrays, air handling units, data centers, commercial buildings, and industrial ventilation systems.
Warehouse and Storage
Fans improve ventilation, climate control, and air quality in warehouses, storage buildings, and distribution centers. These systems help reduce heat, moisture, and stale air buildup in large indoor spaces.
Industrial fans maintain airflow, filtration, and temperature control in sensitive electronics and semiconductor production areas. These systems often require low-vibration, high-efficiency fans in cleanroom-grade configurations.
Industrial fans serve hospitals, labs, and medical facilities by ensuring air exchange, filtration, and pressure balancing across rooms and isolation areas. Many systems support HEPA or ULPA filtration for infection control.
Industrial fans are used to maintain cleanroom airflow, support HEPA filtration, and regulate temperature and humidity in pharmaceutical production spaces. These fans ensure environmental control for both sterile and non-sterile applications.
Industrial fans are used in large-scale or specialized HVAC systems to move air through ductwork, pressurize spaces, and provide conditioned airflow. These fans support air handling units, makeup air systems, and process ventilation where commercial or industrial performance is required.
