The professional Dalap AP PROFI 250 T inline duct fan with higher performance and low noise level is equipped with a temperature-speed logic, which enables automatic speed control depending on the air temperature in the duct. The fan is designed for air extraction in medium-sized rooms, such as offices, shops, kitchens, greenhouses, weekend houses and others. The special housing shape allows for easy installation or maintenance of the unit, for which you need almost no tools. Suitable for ventilation ducts with a length of max. 8 to 10 metres.
Advantages of the Dalap AP PROFI 250 T inline duct fan
- Extraction of high air volumes of 1400 m³/h at a very low noise level
- Integrated electronic speed controller with thermostat
- Motor with ball bearing for continuous operation of 40,000 hours
- smooth running and reliability
-
almost tool-free maintenance, even without dismantling the ventilation system
-
compatible with all round ducts of 250 mm diameter
- installation in rigid as well as flexible ventilation ducts
Designed for easy installation and removal
Thanks to the fan's easy disassembly, you can first complete the ventilation system with the fan's housing unit and later insert the fan's turbine unit. It's simple and requires almost no tools! First remove the securing screws of the fasteners and open the clamps. Then remove the turbine unit from the housing.
Motor with ball bearing
The single-phase motor with ball bearing has two power levels. The motor is equipped with overheating protection with automatic reset. Protection class is IPX4.
Installation anywhere in the ventilation system
The fan can be installed at any point in the duct system – vertically or horizontally. At the same time, several inline duct fans can also be installed in series to increase the pressure build-up and thus the volume of air transported.
For duct systems of 8 to 10 metres
Thanks to its high pressure output, the Dalap AP PROFI inline duct fan is suitable for moving air through a duct with a maximum length of 8 to 10 metres.
Example of thermostat operation
If the air temperature rises 2 °C above the set temperature setpoint, the fan switches to maximum speed. Once the temperature drops below the thermostat setpoint, the fan switches back to the set, lower speed. This type of control ensures temperature maintenance with an accuracy of 2°C.
Control of the electronic module
The fan is equipped with an integrated electronic speed controller and a thermostat, which enables automatic speed control depending on the air temperature in the duct. You set the temperature and the minimum speed using the controls on the control panel. The LED indicator for thermostat operation is located on the front of the fan.
Connection
The connection is very simple, the fan is equipped with a 220 V power cable. After installation, the fan only needs to be connected to the mains power supply and is then ready for operation.
Sufficient power for extraction through filters
The inline duct fan is intended to transport air that is clean and free of mechanical dirt or grease, as otherwise the impeller or the fan itself could be damaged. If the fan needs to be used, for example, in the kitchen or in other locations with grease-laden air, it makes sense to install a grease filter upstream of the unit. The same applies in workshops, warehouses, garages or anywhere the air contains contaminants of various kinds. Here, a filter matching the filter class should be installed upstream of the fan.
