With models ranging from light duty, low investment versions to industrial grade, fully customizable configurations, Peerless' Axial Propeller Fan series has a cost effective, easily installable solution to fit your needs.

While many propeller fans on the market today are positioned as the lowest-cost ventilation option having minimal user-friendly features, Peerless stands apart by offering lightweight, dynamically balanced aluminum blades, carbon steel hubs, multiple speed control options, and heavy mounting plates, all of which keep noise levels low and airflow high.

Low Noise

Propeller fans often end up mounted on exterior building walls near personnel traffic areas, and without the weather protection of building canopies or soffits. Peerless helps alleviate any concerns by providing a variety of safety grilles, drive covers, and discharge shutters to keep personnel safe and hold weather out.

Weather and Safety Options

Installing a propeller fan is arguably the easiest fan style to install. Since all of the fan’s components are pre-mounted onto a rigid, square mounting plate, all that is needed onsite is to cut and frame an opening, lift the fan in place, and bolt down the mounting panel in each of the four corners. Caulk or flash the perimeter, hook up the wiring, and you’re done!

Low-Impact Installation

What traditional wall fans typically lack in performance and strength, Peerless' line of Axial Propeller Fans more than makes up for with uniquely engineered capabilities including any-orientation mounting, direct and belt drives, and multiple customization options.

Axial Propeller Fans

Built for extreme environments, abrasive material transfer, and heavy-duty air handling, Peerless' Industrial Process Blowers set the standard in challenging, continuous-duty applications.

Each project has its own unique demands for fan installation orientation, service access, motor position, drive type, and drive supports. Our Industrial Process Blower series is specifically designed to offer the widest range of AMCA Standard Arrangement configurations, giving you the greatest flexibility for installation.

Wide Selection of Arrangements

Super abrasive materials can wreak havoc on standard-duty fans, eating up housing sidewalls, deteriorating fan blades, and overloading motors. Our Industrial Process Blower M models are specifically tailored to these exceptional demands, with options including ultra-heavy housings, reinforced fan wheels, oversized shafts, and severe-duty bearings.

Abrasive Material Handling

Exhausting industrial processes typically involves handling entrained particulates at elevated temperatures, and often requires higher discharge pressures in order to push through long discharge ducting or end-of-line scrubbers. We offer Industrial Process Blower A models for precisely these applications.

High Pressure Conveying Air

Industrial material handling applications require the toughest, most reliable equipment. Peerless' Centrifugal Industrial Process Blowers are precision engineered for exactly these demanding duties and environments.

Centrifugal Industrial Process Blowers

Where accurate pressure control at low volumes is paramount, Peerless' Radial Pressure Blowers are the ideal solution.

High density and long distance material conveyance systems require steady, high pressure supply airflow in order to mobilize materials for downstream transfer. Our PW and PWB series Radial Pressure Blowers are engineered to provide smooth, high pressure conveyance air up to 12" and 15" SP respectively.

Exhaust streams from laundry equipment, kitchen hoods, and other industrial processes of all types are inherently loaded with dirty particulates, vapors, and gases. Where these contaminants will build up on normal centrifugal fan wheels, reducing performance, our Radial Blade wheels solve this problem with their self-cleaning, no cavity, low friction design that naturally spins off soils.

Dirty Air Handling

Need to satisfy a strict regulatory or engineering specification, or provide an end-user with ultra-high confidence in our fans' performance? Our Radial Pressure Blowers carry the AMCA Certified Performance seal, assuring buyers that they are designed, tested, and guaranteed to perform as promised.

AMCA-Certified Performance

Designed around our self-cleaning, high-efficiency radial blade wheel, Peerless' Centrifugal Radial Pressure Blowers adeptly handle your low volume, low or high pressure, small industrial applications.

Centrifugal Radial Pressure Blowers

Custom site-built air handlers, multiplex fan arrays, high temperature air circulation, and embedded installation are just a few of the design challenges that Peerless' Plenum and Plug Fan models easily solve.

Dryers, ovens, auto-claves, and similar process equipment often require consistent, reliable hot air recirculation as part of their design, which are exactly the type of tough applications that our Plug Fans are strategically designed to handle.

Hot Air Circulation

Some of the world’s largest, most complex office buildings receive clean ventilation air from relatively simple air handling systems known as ‘fan arrays’. Our Plenum Fans are just the type of models intended for these arrays, where multiple stacked fans directly pressurize an air plenum, creating and distributing comfortable air throughout the facility.

Direct Plenum Pressurization

With larger diameter front- and backplates creating a unique diffusing area to smooth out discharge airflow, our Synergy Plenum and Plug Fan models utilize a proprietary diffuser wheel to convert kinetic energy into pressure energy at very high efficiencies and very low noise levels.

Best-In-Class Performance

Peerless' Plenum and Plug style fans offer a wide variety of unique system design and installation options, from custom compact air handlers to massive site-built direct plenum arrays.

Plenum & Plug Fans

Tubular Blowers best fit into applications needing quiet, consistent ventilation airflow, delivered in the smallest equipment footprint possible. In addition, Peerless Tubular models can be configured for any-orientation installation, useful for roof- or wall-mount systems.Minimum Equipment Footprint

Some projects are completely tapped for utility equipment space, whether the case be a packed roof, no access to the roof (such as in a shared sublet), or having a landlocked site with no exterior equipment space. In these cases, our Tubular Blowers are an excellent solution, installing inline with the air ducting and needing no additional space for a traditional housed fan.

Minimum Equipment Footprint

Since projects with limited space are usually also sensitive to noise, our Tubular Blowers include conversion vanes as standard, and can also have radial inlet vanes added as options. These unique, aerodynamically-designed conversion vanes straightens airflow as it exits the fan housing, virtually eliminating turbulence and vastly minimizing noise.

Quiet, Smooth Airflow

Our Tubular Blowers are available with either direct drives or belt drives, both of which having special mounts that allow for simple service access, designed knowing that the blower will likely be installed overhead and tucked into roof structures. We also offer our Ultra-Swing Fan option, which adds housing hinges and side latches to swing open the shell for full access to all internal components.

Industry-Leading Maintainability

Peerless' space-saving, high-efficiency Tubular Blowers move large volumes of ventilation air without taking up any more space than the ducting itself. Tubular models reduce ducting transitions and fittings, making installation less expensive and faster than housed fans.
