Gable ventilation, controlled With this system, gable ventilation is realised with 130C/140C/Flex 140C on/off cone fans and two steplessly variable AirMaster Blue 130C fans �. Using the stepless, so-called MultiStep principle, this fan combination makes it possible to control the ventilation level without jumps between the individual steps: the ideal solution for pullet rearing or broiler production in temperate climates, where a low ventilation level is required when the birds are first moved in. Based on the birds’ growth, the ventilation rates can increase later. When planning to use the...

Step control Ventilation level [%] Simple and cost-efficient control principle Controlling fans in steps (on/off) is a simple exhaust air control principle to make sure that the ventilation requirements in the house meet your livestock’s needs. The AirMaster 130/140/Flex 140C on/off fans are the ideal solution here. This principle does not provide a fully stepless ventilation control to meet the livestock’s needs, however. Example: Four on/off fans = four steps MultiStep and Dynamic MultiStep Energy-saving exhaust air control principles with the AirMaster Blue series Group 2: two on/off...

AirMaster 130 is the smallest AirMaster fan, based on air flow rate. 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 zinc-aluminium coating. The specially shaped blades are made of glass fibre reinforced plastic. Air guide rails on every blade ensure a high air flow rate 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...

AirMaster 140/ 140C High air flow rates and pressure resistance of up to 100 Pa AirMaster 140 fans feature higher air flow rates, especially when dealing with high counterpressure. They are therefore often used in houses with tunnel ventilation if the housing equipment causes high resistance and thus makes an unobstructed airflow impossible, creating a high counterpressure. 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...

High air flow rates, low energy consumption, good resistance to corrosion AirMaster Flex 140C is a cone fan that combines the best of both worlds. On the one hand, this fan model is equipped with a highquality and very efficient IE3 motor driven by a V-belt. The motor can be provided for any type of power supply. On the other hand, housing and cone are made of a high-quality, corrosion-resistant plastic material. The optimised aerodynamic design of the intake nozzle ensures that the exhaust air is removed from the house without any turbulences. This leads to high air flow rates and low...

Very high air flow rates, stepless control, high energy savings and corrosion resistance 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 flow rates minimum energy consumption high resistance to pressure optimised aerodynamic design very high resistance to corrosion The AirMaster Blue 140C fan has the same dimensions as AirMaster Flex 140C. The excellent aerodynamic design of the...

High air flow rates, stepless control from 0 to 100 %, high energy savings and corrosion resistance 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 steplessly from 0 to 100 per cent, therefore saving considerable amounts of energy, should be used. Big Dutchman especially recommends using this fan in pig houses 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...

LameliaBrown and LameliaBlack Ideal light traps for the entire AirMaster series 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. The two light traps provide the following advantages: ✔ ameliaBrown significantly reduces the L incidence of light, and LameliaBlack almost completely prevents light from entering the building; ✔...
