Wall fansHigh air performance and low energy consumption

Wall fans – efficient and durableThe Big Dutchman wall fans are very versatile with a high performance, low energy consumption and low maintenance costs. They are also corrosion-proof and

made for a long service life. Thanks to the large variety they can be ideally adapted to any type of barn. In addition to steel-frame axial fans, we also offer V-belt

driven fans.Let our experts advise you which solution best fits your requirements.

Axial fans with frameExcellent adjustability

Our axial fans with frame are ideally suited for incorporation into walls. The frame has an aerodynamic shape and is made of high-quality sheet steel. The blades are made of moulded aluminium diecasting and therefore have an exceptionally high degree of efficiency. Our product range includes standard fans (FC) as well as sickle-shaped fans (FE), the latter being more pressure-resistant and quieter.

Advantages4 excellent adjustability;

4 high air capacity at a low energy consumption;

4 low noise level;

4 quick and easy assembly;

4 high corrosion resistance;

4 long service life.

ShuttersThis shutter is a self-actuated closing flap made of PVC. If the fan is at a standstill, the shutter is closed.

Wire mesh guardA wire mesh guard is required if the fan is installed in an accessible location.

Dimensions and installation details

Advantages4 optimised aerodynamics at the air admission and air exit sides for a high air flow rate;4 specially-formed blades ensure optimum operation thus reducing energy costs;4 the shutters open by the air flow pressure and stay open thanks to

balancing weights –> minimal air resistance;4 low noise level;4 stable, robust and simple design;4 easy to assemble and easy to install in the building.

Important componentsCasingThe fan casing consists of galvanized sheet steel, the inside construction is made of high-quality polypropylene for a high corrosion resistance.

Blade and blade hubThe vane has 3 or 5 specially shaped blades made of glass-fibre reinforced plastic. Air guide-rails on every blade ensure a large air capacity combined with a low resistance and thus low energy consumption. The blade hub is made of aluminium.

The 5-blade AirMaster is often installed in barns with a high back pressure (cage houses with tunnel ventilation, use of exhaust air treatment systems).

ShuttersThe shutters are opened by the air flow and then kept open by means of a balancing weight. When the fan stops, the shutters close.

V-belt gearingThe V-belt pulley is made of aluminium and is manufactured as one piece together with the blade hub by diecasting.

The V-belt is pretensioned, further tensioning is therefore not necessary.

Electric motorsWe use high-quality motors with a large voltage range (motor protection IP 55, approved for UL/CSA). The motor is completely closed; a separate cooling fan is not necessary. This means there is no danger of dust entering the motor or overheating of the motor.

AirMasterHigh air performance

Light trapAirMaster with coneBig Dutchman offers two light traps. The previous model reduces the amount of light passing through the fan to a minimum and is thus especially suited for rearing and breeding houses. The air performance is reduced by approx. 12 %.

The new light trap PerforMacs is ideally suited for broiler and laying houses. It has been optimised aerodynamically, reducing the air performance by only approx. 10 %.The segments of both light traps are made of plastic which makes them extremely durable and easy to clean.

Cone fans (VC130) are mainly used in barns with especially large air-flow performance requirements. They are also characterized by a low power consumption.

Areas of applicationOur wall fans are very versatile. Depen ding on the climate zone, different ventilation concepts are possible.Side and cross ventilation are often established by means of axial fans. They pull the air across the barn. Longitudinal ventilation is normally accomplished by means of AirMaster fans as these have a higher air capacity.

In case of tunnel ventilation they pull the air through the barn in longitudinal direction at a high air speed. This is a so-called displacement ventilation at minimum energy consumption. CombiTunnel ventilation is best installed in climate zones with large temperature fluctuations – summer/winter or day/night temperatures.

In the case of decentralized exhaust air extraction via chimneys in the roof, AirMaster fans in the gable can be switched on for additional ventilation on hot summer days.
