It is designed for easy removal for maintenance, for which you need almost no tools. Max. length of the ventilation ducts is 8 to 10 metres.
Advantages of the Dalap AP Profi 250 inline duct fan
-
high airflow of 1400 m3/h even at a very low noise level
- motor with ball bearing – service life of up to 40 000 hours
- smooth operation and reliability
- almost tool-free maintenance, even without dismantling the ventilation system
- compatible with all round ducts with a diameter of 250 mm
- installation in rigid and also flexible ventilation ducts
Designed for easy removal
Thanks to the fan's simple disassembly, you can first complete the ventilation system and only then insert the fan's turbine unit. It is simple and requires almost no tools! First remove the securing screws of the fasteners and open the clamping bands. Then remove the turbine unit from the housing.
Motor with ball bearing
The single-phase motor with ball bearing has two power levels, which you can select using a switch. The motor is equipped with overheating protection with automatic reset. The protection rating 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 in series can also be installed 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 performance, the Dalap AP PROFI inline duct fan is suitable for moving air in a duct with a maximum length of 8 to 10 metres.
Sufficient power for extraction through filters
The inline duct fan is designed to transport air that is clean and free of mechanical dirt or grease, as the impeller or the fan itself could otherwise be damaged. If the fan needs to be used, for example, in the kitchen or in other places with greasy air, it is advisable to install a grease filter in front of the unit. The same applies in workshops, warehouses, garages or anywhere else where the air contains contaminants of various kinds. Here, a filter matching the appropriate filter class should be installed in front of the fan.
Accessories
A necessary part for connecting the fan is a connecting cable, which must be purchased separately.
External modules that can extend the fan with a timer or a humidity sensor.
Connection
Difficulty level: requires specialist knowledge in electrical engineering
Tools required: small flat-blade screwdriver
Time: 15 minutes
1. Remove the cover of the terminal box; here you will find 2 terminals
2. Each terminal is marked with a letter: from the left, the „N“ terminal – for connecting the neutral conductor (blue cable)
