Cabinet
is made of galvanized steel sheet. The cabinet is fitted with a 50 mm layer of soundproofing material inside. The enclosure has circular spigots with single-edge seals for connecting flexible hoses or circular pipes.
Running wheel
is radial with backward curved blades. The impeller is pressed directly onto the outer rotor of the motor.
Motor
EC motor with thermal overload protection. IP44 protection, operating temperature -20 ºC to +40 ºC. Terminal block is located inside the enclosure and is accessible by removing the panel with potentiometer and safety off/on switch.
Speed control
The fan is preset to operate in automatic control mode at constant duct pressure (depending on fan size - CAB-125 100 Pa, CAB-150 to CAB-315 150 Pa, CAB- 355 and CAB-400 200 Pa). For further settings it is necessary to use the digital PROSYS Ecowatt controller (not included), which allows 4 basic control modes - automatic regulation to constant duct pressure, continuous automatic regulation to constant air flow (except CAB-125), proportional mode or ventilation mode with 2 switchable min./max. It is possible to connect a signal from an external device (CO2, temperature and relative humidity sensor), an external pressure sensor with transducer and 0-10 V or 4-20 mA output. The PROSYS Ecowatt controller can control up to 32 fans with different settings in one network. The control allows control via MODBUS-RTU. The PROSYS Ecowatt digital controller in combination with the TIMER RTC Ecowatt module (not included) allows setting up to 3 time programs and holiday operation.
