Tangential cross flow fans, also known as cross-flow or tangential blowers, are crucial components in many industrial and commercial ventilation, heating, and cooling systems. Their compact design, low noise, and ability to provide uniform airflow make them indispensable in applications ranging from HVAC systems to electronics cooling and industrial ovens. The Netherlands, known for its advanced engineering and manufacturing sectors, hosts several top manufacturers specializing in these fans, offering innovative, high-quality products tailored to diverse customer needs.
This article provides an in-depth look at the top tangential cross flow fan manufacturers in the Netherlands, their product features, applications, and what sets them apart in this specialized field.
Tangential cross flow fans are unique due to their airflow pattern. Unlike axial or centrifugal fans, these fans draw air in from one side and expel it perpendicularly across the entire length of the impeller, creating a broad, uniform laminar airflow. This makes them ideal for applications requiring even air distribution over a wide area with minimal noise and vibration.
- Compact and low-profile design suited for tight installation spaces.
- Uniform laminar airflow across the full length of the fan.
- Low noise and vibration, suitable for quiet environments.
- Versatile motor options including AC shaded pole, capacitor motors, and high-efficiency EC (electronically commutated) motors.
- Wide application range including heating, ventilation, air conditioning, electronics cooling, and industrial ovens.
The impeller consists of long, forward-curved blades mounted on a cylindrical drum. The motor is typically mounted outside the airflow path, connected via a shaft, which protects the motor and extends its lifespan.
The Netherlands is recognized for its engineering excellence and innovation in HVAC and industrial ventilation technologies. Dutch manufacturers emphasize delivering customized fan solutions that meet stringent European standards for energy efficiency, noise control, and durability.

Tangential cross flow fans are used across many industries due to their unique airflow characteristics:
- HVAC Systems: Air curtains, ventilation units, and air handling systems.
- Industrial Ovens: Uniform airflow for consistent heating and baking.
- Electronics Cooling: Low noise and uniform airflow for sensitive equipment.
- Medical Equipment: Cooling and air circulation in devices.
- Commercial Refrigeration: Food display units and cold storage.
- Fireplaces and Heaters: Flame effect fireplaces and convectors.
Their ability to provide broad, even airflow with low noise makes them especially valuable in environments where comfort and precision air control are critical.
The fan's impeller rotates inside a tubular housing. Air enters from one side, is accelerated by the forward-curved blades, and exits perpendicularly across the length of the impeller. A vortex tongue inside the housing directs airflow and creates a pressure difference that drives the air through the fan, producing a broad, uniform airflow with low turbulence.
This design allows for:
- Even airflow distribution over large surfaces.
- Reduced noise and vibration compared to other fan types.
- Compact installation in thin or narrow spaces.
- Flexible motor placement for easy maintenance.
Dutch manufacturers often provide tailored solutions to meet specific application needs, including:
- Impeller size customization: Diameter and length adjusted to airflow and pressure requirements.
- Motor options: Choice between AC, DC, or EC motors depending on efficiency and control needs.
- Motor side configuration: Left or right side mounting to fit installation constraints.
- Speed control: Integration of PWM, 0-10V, or other control signals for precise airflow adjustment.
- Material selection: Special coatings or materials for high-temperature or corrosive environments.
- Noise reduction: Use of sound-absorbing materials and optimized blade designs.
These options ensure that customers receive fans optimized for their unique operational conditions, enhancing performance and longevity.
With increasing focus on sustainability, Dutch manufacturers emphasize energy-efficient designs. Electronically commutated (EC) motors are widely adopted for their superior efficiency, lower power consumption, and quieter operation compared to traditional AC motors. These motors allow precise speed control, reducing energy use during partial load conditions.
Additionally, many manufacturers comply with European eco-design directives, ensuring their fans meet or exceed environmental standards. This commitment helps customers reduce their carbon footprint and operational costs.
