CA duct fans – with different control options & maximum efficiency
.jpg "Category CA duct fans"){kind=icon}
Features Common to All Vortice CA Models
All series in the CA range are based on proven centrifugal technology featuring backward-curved impellers for high pressure buildup and maximum efficiency. They share the following key characteristics:
- Ball-Bearing Motors: Guarantee continuous operation (at least 30,000 operating hours) and minimal wear.
- High Pressure Buildup: Perfectly suited for complex, winding duct systems.
- Compact Design: Direct installation into standard duct diameters (e.g. nominal diameters 100 to 315 mm).
Comparing the 4 Model Series: Which Fan Suits Which Application?
| Series | Casing Material | Motor & Control | Key Feature |
|---|---|---|---|
| CA MD E | Robust sheet steel (coated) | AC motor (3-speed) | The durable metal classic for standard duct systems. |
| CA V0 E | Self-extinguishing plastic (V0) | AC motor (2–3 speed) | Lightweight, corrosion-resistant, double insulated (no grounding required). |
| CA ES 0-10V | Phosphatised steel (hammer finish) | EC motor (0–10V stepless) | Maximum energy savings & stepless control. |
| CA WE D E | Weatherproof sheet steel (polyester) | AC motor (3-speed) | Specifically designed for external wall mounting. |
Detailed Overview of Individual Series
1. CA MD E Series – The Robust Metal Standard
The CA MD E Series forms the backbone of the CA family. The casing is made of protected, powder-coated sheet steel, making the fan exceptionally resistant to mechanical strain.
- Application: In-line installation within duct systems in workshops, storage rooms, offices, or catering establishments.
- Control: 3-speed AC motor, controllable via external step switches or controllers.

2. CA V0 E Serie – Plastic Casing for Humid Rooms & Easy Installation
The CA V0 E Series relies on a casing made of high-quality, self-extinguishing V0 plastic. This material is 100% corrosion-free and electrically insulated.
- Application: Environments with higher humidity (e.g. sanitary rooms, washrooms) and locations requiring Protection Class II (double insulation).
- Advantage: Lower dead weight and integrated protective grille on the intake side.
3. CA ES 0-10V Series – Energy-Saving Thanks to EC Technology
"ES" stands for Energy Saving. This series is equipped with state-of-the-art EC motors that consume up to 50% less power compared to AC motors.
- Application: Commercial properties and buildings with continuous ventilation needs where operating costs must be reduced.
- Control: Stepless adjustment via a 0–10 V signal (e.g. using CO2 sensors, humidity sensors, or building management systems).
4. CA WE D E Series – External Wall Fans
"WE" stands for Wall External. Unlike other duct fans, this model is not installed inside the duct, but mounted directly on the building's exterior wall.
- Application: Buildings with no interior space for a duct fan, or where ventilation noise needs to be shifted outdoors.
- Special Feature: The casing is specially engineered to be weatherproof (IPX5 protection against water jets) and channels exhaust air outwards.
Important Selection Advice
When choosing the appropriate model, pay attention to the required duct diameter (nominal size 100, 125, 150, 200, 250, or 315 mm) as well as the necessary air flow rate (m³/h).
CA duct fans are among the most versatile solutions in the field of duct ventilation. They stand out from other series primarily due to their wide variety of models, different materials, as well as numerous control options and noise-level variants.
