AirMaster & Co.

With regard to its air flow rates, AirMaster 130 is the smallest fan of the AirMaster series. Like all AirMaster fans, AirMaster 130 is mainly installed in the gable and also available with a cone. The metal housing has a long-lasting zincaluminium coating.

The specially shaped blades are made of glass fibre reinforced plastic. Air guide rails on every blade ensure a high air performance combined with a low resistance and thus low energy consumption. The airflow opens the shutters, which are then kept open without any losses by means of a balancing weight.

When the fan stops, the shutters close automatically and are locked magnetically. The V-belt pulley is made of aluminium and is manufactured as one piece together with the blade hub by diecasting. The V-belt is pre-tensioned, i.e. a belt tensioner is not necessary.

AirMaster 140 fans feature a higher air performance, especially when dealing with high counterpressure. They are therefore a good choice in barns with tunnel ventilation if the housing equipment causes high resistance and thus makes an unobstructed airflow impossible.

Material quality, aerodynamics and workmanship meet the same high requirements as AirMaster 130, while the following quality features additionally apply for AirMaster 140 fans:

• blades with higher stability
• V-belt pulley with higher stability
• connection between hub and the six blades with higher stability
• use of 2.0 HP IE3 motors (high energy efficiency) according to the European Ecodesign Directive

AirMaster Flex 140C is a new cone fan that combines the best of two worlds. This fan model is equipped with a V-belt driven, high-quality and very efficient IE3 motor, which can be provided for any type of power supply.

Additionally, housing and cone are made of a high-quality, corrosion-resistant plastic material. A very important feature is the optimised aerodynamic design of the intake nozzle. The exhaust air is removed from the barn without any turbulences, which leads to a high air performance and low power consumption.

The motorized and well-insulated shutter is absolutely airtight and therefore ideal for the colder season. An emergency opening can also be connected. With a cone diameter of 1750 mm, AirMaster Flex 140C is the largest fan of the Big Dutchman product range.

The AirMaster fans of the Blue series are a new addition to the Big Dutchman product range. They are next-generation fans and feature a directly driven, steplessly variable motor. The AirMaster Blue 140C fan has five outstanding characteristics:

• very high air performance
• minimum energy consumption
• high resistance to pressure
• optimized aerodynamic design
• very high resistance to corrosion

The AirMaster Blue 140C fan has the same dimensions as AirMaster Flex 140C.

The AirMaster Blue 130 fan has the same dimensions as AirMaster 130 and is therefore the ideal solution for retrofitting. This is especially relevant where a fan that can be controlled from 0 to 100 percent, therefore saving considerable energy, should be used.

Big Dutchman especially recommends using this fan in pig housing because it is resistant to ammonia and thus also to corrosion. The AirMaster Blue 130 fan can be supplied with or without cone. The most important feature of this fan is the newly developed motorized shutter. 

Big Dutchman’s newly developed light trap, Lamelia, is available in two versions. LameliaBrown has a light reduction factor of 6,000 :1 and is thus ideal for layer and broiler houses. LameliaBlack’s much higher light reduction factor of 7,100,000 :1 makes this light trap a great solution specifically for breeder houses.

Axial fans are perfect for installation in the wall, especially in smaller barns and when using cross ventilation. Their frame has an aerodynamic shape and is made of stable plastic or corrosion-resistant metal. The blades are made of aluminium in a moulded diecasting process and are exceptionally efficient.

Big Dutchman differentiates between FC, FF and FN fans, based on the shape of the blades. The serrated blades of the FF and FN fans imitate the wings of an owl during its silent flight (bionics). FF and FN fans therefore consume less power; they are extremely resistant to pressure and operate at a low noise level.
