Inline Fans
TD-MIXVENT
In-line Mixed Flow Duct Fan
The TD-MIXVENT series is an in-line duct fan specially designed to maximize the airflow performance with minimal noise levels in a small, compact housing. This makes the TD-MIXVENT series the ultimate solution for small to medium sized ventilation installations which require a high airflow to pressure ratio and occupy minimum space (e.g., false ceiling voids, cabinets and many other limited space environments).
TD-SILENT
In-line Mixed Flow Duct Fan (Designed for Rigid Duct Applications)
The TD-SILENT fans are extremely quiet, low profile fans manufactured in the tough reinforced plastic material. Sound waves are directed through the perforated inner skin and absorbed by a layer of sound-absorbent insulation. These fans are fitted with rubber gaskets on the inlet and outlet to facilitate installation, absorb vibrations, and provide a virtually air-tight seal.
PV-DEDPV
Dryer Exhaust Duct Power Ventilator
The PV-DEDPV is a UL 705 listed Dryer Exhaust Duct Power Ventilator. It effectively helps residential clothes dryers overcome the high static pressure caused by long duct runs between the dryer and wall or roof cap.
PV-POWERVENT
In-line Centrifugal Duct Fan
The PV-POWERVENT series of direct drive centrifugal in-line duct ventilation fans consists of six model sizes 4", 5", 6", 8", 10" and 12.4" respectively. All models are designed for direct connection in-line with standard diameter round ducting. Airflow performance values range from 153 CFM (PV-100X) up to 943 CFM (PV-315X).
PRF
Radon Mitigation Fan
PRF fans are specifically designed for radon mitigation. The fully-sealed plastic fans feature backward inclined centrifugal blower/motors capable of handling up to 1" of static pressure. The PRF series has duct lips sized for an easy fit with standard PVC couplings typically used in radon mitigation applications. Additionally, the PRF was engineered with large, easily accessible, watertight electrical boxes for unobstructed wiring process.
SMXDK
Direct Drive Mixed Flow Fan
Model SMXDK mixed flow fans are inline ducted fans that can be used in exhaust, supply, or return air applications. Mixed flow fans act as a hybrid between axial and centrifugal fans. Meaning, they produce a lot of air such as axial fans, but they can handle higher pressures like centrifugal fans. When these technologies come together, the fan ends up being more efficient and quieter than similar tubular centrifugal fans.
SMXDK-HT
Direct Drive Mixed Flow Fan
SMXDK-HT series is a direct drive mixed flow fan specially designed to maximize the airflow performance by acting as a hybrid between an axial and centrifugal fan. This HT (high temperature) model can provide emergency heat and smoke ventilation in the event of a fire, which can provide valuable time to people exiting or emergency personnel.
SQB
Belt Drive Square Inline Centrifugal Duct Fan
SQB square in-line duct mounted fans are available in sizes 7 through 42, moving from 100 to over 24,000 CFM, with high static pressure capability up to 3-1/2". SQB units are the perfect selection for clean air applications where space is a leading consideration. The compact housing with removable access doors and side discharge can be mounted in any orientation. AMCA licensed performance and UL listing assure that you've made a reliable selection.
SQD and eSQD
Direct Drive Square Inline Centrifugal Duct Fans
The SQD square inline duct mounted fan is available in sizes 6 through 15, moving up to 2,800 CFM, with static pressure capability up to 1". eSQD with electronically commutated (EC) motors are square inline duct mounted fan is available in sizes 8, 10, and 12. SQD units are the perfect selection for clean air applications where space is a leading consideration. The compact housing with removable access doors and side discharge capability can be mounted in any orientation.
CTB and CTBRHUL
Inline Tubular Centrifugal Fans
The Inline Tubular Centrifugal (CTB) series offers one of the widest ranges of sizes, horsepower, and performance in the industry. Models CTB are high capacity belt drive tubular centrifugal fans rated from 300 to 20,000 CFM, with static pressure capability up to 2-1/2". These fans are designed for commercial and industrial in-line applications that demand quiet, efficient and reliable air movement. They are used to exhaust air from or supply air to commercial and industrial applications, such as, general building ventilation, enclosed garages, paint spray booths, heat and smoke ventilation systems, restaurant and kitchen exhaust ventilation, historical buildings with limited roof space and restrictive duct lengths, and other applications where air is moved through a duct system against moderate static pressure.
CFD
Forward Curved Belt Drive In-line Duct Blower
The Forward Curved Belt Driven Inline Duct Blowers (CFD) is designed for supply, exhaust or duct return applications. The CFD is an economical fan model designed to run quietly and efficiently in cooling, heating, and ventilating applications.
Losone Cabinet Inline Fans
Cabinet Inline Fans
The Losone Select Series cabinet inline duct fans feature forward curved centrifugal wheel design that moves up to 704 CFM against static pressures up to 1" w.g. These commercial-grade inline ventilators use resilient-mounted, low RPM motors for quiet HVAC operation in commercial and institutional buildings. Speed controllable with removable blower assemblies for easy maintenance. Suitable for ducted or non-ducted inline ventilation applications including restrooms, offices, conference rooms, and general exhaust ventilation systems.
PCD-IL New
Premium Choice Inline Fans
High-performance inline fans, designed for quiet, continuous operation in both exhaust and supply air applications—ideal for residential and light commercial environments. Powered by an energy-efficient EC motor (commonly referred to as a DC motor) and PCD-IL models support both single-speed and two-speed operation. Superior performance with AutoFlo™ technology and static pressure capability of up to 1.0 in.wg. Multiple speed options, complemented by a built-in rotary knob for manual speed adjustment.
