The CasaFan EQ EQ 40/4 T is a robust wall-mounted axial fan featuring a square wall plate, designed for commercial and industrial applications. Constructed from powder-coated, corrosion-protected sheet steel and powered by a ball-bearing AC motor, it extracts large volumes of air directly through the wall to the outside or into adjacent areas.
Your Advantages at a Glance
Industrial Design
Square wall plate made of galvanized sheet steel with additional protective coating against corrosion during continuous operation.
Speed-Controllable
The single-phase or three-phase AC motor can be speed-adjusted using suitable speed controllers or step transformers (not included).
Ball-Bearing Motor
Maintenance-free AC motor featuring sealed ball bearings and thermal overload protection for high reliability. Insulation class F. All models reversible (except EQ 20/4 M and EQ 25/4 M).
Applications
Due to its compact mounting depth combined with high airflow rates, the CasaFan EQ series is ideal for:
- Commercial & Production Areas: Direct extraction of stale air and moisture.
- Workshops & Warehouses: Continuous air circulation and ventilation.
- Catering Service Rooms & Utility Areas: On-demand supply and exhaust ventilation.

Accessories & Installation Note
Important for Practical Use: The fan is supplied without a speed controller. To adjust the airflow rate depending on the motor type (230 V or 400 V), a suitable CasaFan control unit or step transformer is required. To prevent cold air ingress in winter when turned off, we recommend installing an external shutter grille (e.g., CasaFan HKS / MVK).

Frequently Asked Questions about the CasaFan EQ Series (FAQ)
Understanding the Model Designation (CasaFan Nomenclature)
The naming structure of CasaFan wall-mounted axial fans follows a clear scheme:
- EQ: Product series for square wall-mounted axial fans featuring a steel wall plate.
- Number before the slash (e.g., 20, 25, 30, 40): Nominal diameter of the impeller / wall opening in centimeters (e.g., 30 = 300 mm).
- Number after the slash (e.g., 2 or 4): Number of motor poles (2-pole for high pressure; 4-pole = approx. 1,400 RPM for quieter operation).
- Letter at the end (M or T):
- M = Single-phase alternating current (230 V / 50 Hz)
- T = Three-phase alternating current (400 V / 50 Hz)
