Wall fans with high air performance and low power consumption
Fans of the airmaster series have been an important part of the big dutchman product range for more than 40 years. They are the core of many ventilation systems and used by livestock farmers all over the world. Our airmaster fans are characterised by:
- High air performance;
- Low power consumption;
- Reduced maintenance costs;
- High resistance to corrosion;
- Robustness.
Airmaster 130 / 130c
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.
Main advantages
- High air performance;
- Specially shaped blades ensure optimum operation, thus reducing energy costs;
- Low noise level;
- Compact design;
- Air flow pressure opens the shutters, which stay open thanks to balancingweights: little air resistance;
- Rugged design;
- Good price : performance ratio;
- Simple assembly without external assistance;
- Long service life.
Airmaster 140 / 140c
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
Main advantages
- High air performance;
- Pressure resistance of up to 100 pa;
- Specially shaped blades ensure optimum operation, thus reducing energy costs;
- Low noise level;
- Air flow pressure opens the shutters, which stay open thanks to balancing weights: little air resistance;
- Stable and robust construction;
- Compact design;
- Good price : performance ratio;
- Simple assembly without external assistance;
- Long service life.
Airmaster flex 140c
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.
Main advantages
- High air performance;
- Resistance to pressure;
- Excellent aerodynamic design of the intake nozzle;
- Cost-efficient but high-quality ie3 motor that can be provided for any type of power supply;
- Low noise level;
- High-quality materials: fan made of polypropylene and stainless steel for corrosion prevention;
- Shutter closes airtight and is wellinsulated and therefore ideal for the colder season;
- An important emergency opening system can be connected;
- Good price : performance ratio;
- Long service life;
- Unassembled upon delivery for a low shipping volume and thus lower transport costs.
Airmaster blue 140c
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.
Main advantages
- As a steplessly variable fan and in combination with the dynamic multistep exhaust air principle, currently the most energy-efficient solution for ventilating livestock buildings;
- High resistance to pressure of up to 100 pa;
- Very low noise level;
- Directly driven, with a stable connection between hub and blade for low maintenance requirements;
- Motorized shutter closes the fan airtight;
- An important emergency opening system can be connected;
- High material quality: fan made of polypropylene and stainless steel;
- Protection rating ip 65;
- Unassembled upon delivery for a low shipping volume and thus lower transport costs.
Airmaster blue 130 / 130c
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.
Main advantages
- Steplessly variable from 0 to 100 percent and in combination with the multistep und dynamic multistep exhaust air principles currently the most energyefficient solution for ventilation;
- High resistance to pressure of up to 100 pa;
- Very low noise level;
- Motorized shutter closes the fan airtight;
- An important emergency opening system can be connected;
- Directly driven, with a stable connection between hub and blade for low maintenance requirements;
- High-quality materials: fan made of polypropylene and stainless steel for corrosion prevention;
- Protection rating ip 65;
- Assembled upon delivery for a fast installation on site.
Lameliabrown Perfect light trap for the entire airmaster series
The lameliabrown light trap, newly developed by big dutchman, has a light reduction factor of 6000:1 and is thus perfect for use in layer and broiler houses.
Main advantages
- Only a low reduction of the fans’ air performance;
- No incidence of direct sunlight;
- Light trap segments made of high-quality plastic for a long service life and easy cleaning;
- Fast installation thanks to the integrated spacers
Axial fans excellent controllability, low power consumption
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.
Main advantages
- Excellent controllability;
- Low energy consumption, especially of the ff and fn fans;
- Low noise level;
- Fast and easy installation;
- High corrosion resistance;
- Long service life.
