Crossflow Blowers
Regal Rexnord crossflow blowers(also called tangential or transverse - flow blowers) are unique air - moving devices that produce a wide, uniform “air curtain” by drawing air in across the length of a cylindrical impeller and discharging it in a broad, laminar sheet perpendicular to the intake — an ideal flow characteristic for applications requiring consistent airflow distribution across a wide path, such as air curtains, process drying, glass tempering, and electronic cooling.Under the Fasco brand, our crossflow blower line encompasses a broad range of diameters, lengths, motor voltages, and speed options — from compact 60mm - diameter blowers for electronics cabinet cooling to large 150mm - diameter blowers for overhead air curtains and product - drying tunnels.Equipment designers select Fasco crossflow blowers because they produce a remarkably uniform outlet velocity profile without the complex ductwork, flow straighteners, and multiple - nozzle assemblies required to achieve similar results with axial or centrifugal fans.With low - profile, elongated housing configurations that integrate into narrow spaces, whisper - quiet operation, and speed - controllable AC and EC motor options, our crossflow blowers solve the airflow - distribution challenges that other fan types cannot address effectively.

Uniform “Air Curtain” Discharge Profile
The inherent tangential - flow characteristic produces an even velocity across the entire blower length — essential for air curtains, drying uniformity, and glass - surface cooling.
Compact, Elongated Form Factor
Length - to - diameter ratios accommodating installations in narrow, wide spaces(above doors, inside equipment cabinets, under conveyors) where centrifugal or axial fans would require extensive ducting.
Whisper - Quiet Operation for Occupied Spaces
Low blade - pass frequency and absence of the tonal peaks characteristic of axial fans make crossflow blowers the preferred choice for indoor air curtains and office - environment electronic cooling.
Multiple Motor Speeds & Voltages
Available in shaded - pole, PSC, and EC motor configurations with single and multi - speed taps, providing the exact airflow control required by the application without external speed controllers.
Standard & Custom Lengths to Match Application Width
Stock blower lengths cover common air - curtain and equipment widths; custom lengths are available for OEM applications where standard increments do not fit the machine envelope.
Simple Snap - Fit or Flange Mounting
Designed for rapid assembly into OEM equipment, with housing features that enable screw - less snap -in installation or standard bolt - flange mounting as the application requires.
Crossflow Blowers for Air Curtain & Entrance Thermal Barriers
Air curtains create an invisible barrier of moving air across building entrances, separating conditioned indoor air from unconditioned outdoor air without the physical obstruction of a door.Crossflow blowers are the nearly universal technology for air - curtain systems because their uniform - width discharge covers the entire door opening with a consistent air velocity — a requirement that cannot be met by multiple discrete fans without gaps and velocity variations.Fasco crossflow blowers power air curtains in retail stores, commercial kitchens, cold - storage warehouses, and industrial loading docks, where they reduce heating and cooling energy losses by 30 % to 50 % compared to unprotected openings, while also deterring flying insects and maintaining indoor air quality.For OEM air - curtain manufacturers, Fasco provides blowers with the specific length, speed, and mounting configuration required for their product line, with the consistent quality and on - time delivery that enables lean manufacturing operations.
Crossflow Blowers for Process Drying, Glass Tempering & Electronics Cooling
The uniform air distribution of crossflow blowers solves drying and cooling problems across diverse industries.In food - processing and packaging lines, Fasco crossflow blowers provide the consistent, gentle airflow that removes surface moisture from products before labeling, coding, or packaging — without the product displacement or localized over - drying that point - source fans cause.Glass - tempering lines use crossflow blowers to cool glass sheets uniformly, preventing the localized stress buildup that causes spontaneous breakage.Electronics cooling applications — server racks, kiosk displays, and instrument cabinets — employ compact crossflow blowers that provide even airflow across the entire width of a circuit board or heat - sink array from a low - profile mount.For each specialized requirement, Regal Rexnord application engineers help identify the optimal blower diameter, length, and speed to achieve the target airflow distribution and velocity at minimum energy consumption and noise.
