The Systemair RVK 150E2-L Sileo is a circular duct fan designed for ventilation systems. It is speed-controllable, features integrated thermal contacts for motor protection, and is suitable for installation in any position. The unit includes a mounting bracket and is designed for maintenance-free operation.
Product description
The casing is manufactured from PP fibreglass reinforced plastic, providing a tight, leak-resistant structure. The fan is equipped with high-efficiency backward-curved blades and an external rotor motor. It is suitable for wet room applications due to the IP44-rated terminal box, though it is recommended to run the fan with dry air periodically to prevent moisture buildup.
Technical parameters
The following nominal data applies to the RVK 150E2-L Sileo:
- Voltage: 230 V
- Frequency: 50 Hz
- Phase: 1 ~
- Input power (P1): 109 W
- Current: 0.48 A
- Max. airflow: 0.2 m³/s
- R.p.m.: 2527 r.p.m.
- Capacitor: 3 µF
- Weight: 3.2 kg
- Max. temperature of transported air: 70 °C
- Sound pressure level at 3 m: 44.8 dB(A)
Installation and wiring
The fan is designed for duct installation. The FK mounting clamp facilitates easy installation and removal while preventing vibration transfer to the duct. The unit can be speed-controlled via a stepless thyristor or a 5-step transformer. The motor is protected by integrated thermal contacts with manual reset.
Wiring must be performed according to the provided diagram, ensuring correct connection of the phase (L), neutral (N), and earth (yellow/green) wires.
Accessories
The fan is compatible with a wide range of Systemair accessories, including:
- Speed controls: RE 1.5, REU 1.5, REE 1, STL 1.5, FRQS-E-6A, FRQ5S-E-6A
- Heaters: CB 150-1.2, CB 150-2.1, CB 150-2.7, CBM 150-2.1
- Other: LDC 150-600 Silencer, FFR 150/FGR 150 Filter cassettes, FK 150 Fast clamp, SG 150 Protection guard, RSK-150 Back draft damper
Practical help
Common problems
Motor overheating
The unit has integrated thermal contacts with manual reset. Ensure the fan is not blocked and airflow is sufficient.
Wet room application moisture
While the fan is IP44 rated, it is recommended to run the fan with dry air periodically to prevent moisture buildup.
Before use
- Verify power supply matches 230V/50Hz
- Ensure the mounting location supports the 3.2kg weight
- Check that the ducting is compatible with the 150mm diameter
- Confirm the speed controller (if used) is compatible (e.g., thyristor or 5-step transformer)
Specs in practice
- Thermal contacts
- Safety feature to protect the motor from overheating.
Images and diagrams
- The wiring diagram shows a 1-phase connection (230V) with a capacitor (C) and connections for N, L, and Earth (yellow/green).
Model compatibility
- Compatible with various Systemair accessories including RE/REU/REE speed controls, CB duct heaters, and FFR/FGR filter cassettes.
