The axial wall-mounted extractor fan A-E 50/4 T - 400V/50Hz is a high-performance system solution for the ventilation of commercial and industrial buildings. Specially engineered for direct wall mounting, this industrial fan moves large volumes of air directly through external walls – ideal for halls, workshops, catering facilities, and warehouses. Equipped with a square inlet nozzle wall plate, a ball-bearing external rotor motor, and a weather-resistant powder coating, the A-E series guarantees maximum operational reliability and continuous operation capability.
Your Benefits at a Glance
Industrial-Grade Construction
Square nozzle wall plate made of galvanized sheet steel with scratch-resistant, black polyester powder coating and detachable protective grille conforming to UNI ISO 13857.
Steplessly Speed-Controllable
Demand-based airflow regulation: The motor speed can be precisely controlled via an external stepless electronic controller or a 5-step transformer.
Durable External Rotor Motor
Maintenance-free, ball-bearing motor with thermal overload protection (IP54, Protection Class I) and a statically/dynamically balanced sheet steel impeller.
Applications & Areas of Use
The wall-mounted fans of the A-E series have been specifically developed for applications requiring reliable extraction of high air volume rates at low to medium static pressure resistance:
- Production Halls & Workshops: Reliable extraction of heat, moisture, fumes, and stale indoor air.
- Warehouses & Logistics Centers: Effective air exchange and room temperature stabilization during continuous operation.
- Catering, Offices, Sports Facilities & Commercial Premises: Compliance with statutory air exchange rates and protection against heat build-up.

Important Notes on Installation & Accessories
Control & Cold Air Protection: The wall-mounted fan is delivered without an integrated switch/controller. For demand-based adjustment of the airflow performance, please select a suitable stepless speed controller or step transformer from our accessory range. To prevent cold air ingress when the fan is switched off, we recommend pairing it with a matching external louver shutter on the outer wall face. All electrical wiring and connections must be carried out by a qualified electrician in accordance with applicable VDE standards and electrical safety regulations.
Important Electrical & Connection Notice (T Models)
Models belonging to the T series are three-phase AC fans (400 V / 50/60 Hz). A suitable three-phase mains supply is required for operation; the unit does not include a standard 230 V plug. Hardwired electrical connection must be carried out strictly by a qualified electrician.
Frequently Asked Questions (FAQ) about the A-E Series
How is the model name structured? (Nomenclature Explanation)
The designation of the CasaFan A-E wall-mounted extractor fans follows a clear structure that allows you to read off the core technical characteristics directly:
- A-E: Product series of axial wall-mounted extractor fans with a square inlet nozzle wall plate.
- First number (e.g. 25, 30, 40, 50, 56, 63): Nominal/blade diameter of the impeller in centimeters (cm).
- Number after the slash (/2, /4, or /6): Number of motor poles:
- /2 = 2-pole motor: Nominal speed approx. 2,500 rpm
- /4 = 4-pole motor: Nominal speed approx. 1,400 rpm
- /6 = 6-pole motor: Nominal speed approx. 1,000 rpm
- Letter at the end (M or T): Electrical supply type:
- M (Monofase): 230 V / 50 Hz single-phase AC.
- T (Trifase): 230 / 400 V ~ 50 Hz three-phase AC (heavy current).
