Inline duct fan with two speed settings, switchable via the housing switch. High pressure at a low noise level, motor removable for maintenance without tools. Available in 4, 6, 8 and 10 inch (100–250 mm).
APPLICATIONS
The fans in the AP series combine the versatility and high performance of axial and radial fans. They were specially developed for the supply and extract air of rooms where high pressure and a strong airflow at a low noise level are required. The semi-radial fans are compatible with air ducts from Ø 100 to 315 mm. Extract air systems with a Dalap AP fan at their core are the best solution for ventilating bathrooms, kitchens and other damp rooms. Also suitable for ventilating flats, houses, shops, cafés etc.
DESIGN
The housing is made of flame-retardant polypropylene. The intake spigot is fitted with a collector to ensure an even air inflow into the fan. The hemispherical impeller and the specially profiled blades increase the circulation speed of the airflow and provide higher pressure and higher performance compared to conventional axial fans. The diffuser, the specially profiled impeller and the guide vanes at the outlet of the fan housing distribute the airflow so that the best combination of high performance, high pressure and low noise level is achieved.
MOTOR
The fans in the Dalap AP PROFI series are fitted with single-phase, two-speed motors with low power consumption. The motors are equipped with thermal overheating protection to prevent motor overload. Ball bearings extend the service life of the motors to up to 40.000 hours of continuous operation. The motors have protection class IP X4.
INSTALLATION
The fans can be installed at any point in the ventilation system. Several fans can also be installed in one system:
Parallel installation – to increase the airflow
Series installation – to increase the operating pressure
The fan housing is fitted with a flat mounting plate for fixing the fan to the wall. The mounting plate can be attached in any position to make installation and wiring easier.
