PWS2 Roof Fan
PWS2 Roof Fan
The document provides technical specifications and operational details for the PWS2 roof fan and the ARO 0.6 speed controller, designed for high-ventilation demand cabinets with low noise requirements. The PWS2 fan is noted for its energy efficiency and reduced noise levels compared to the PWD-4W ventilation panel.
ARO 0.6 Speed Controller
The ARO 0.6 is an autotransformer controller used to manually adjust the speed of the PWS2 fan. It features a five-step transformer speed control to balance performance and noise, with the fifth step allowing full power usage. It is designed to have no adverse impact on the power grid and includes a resettable thermal switch. The controller complies with PN-EN 61558-2-13 standards and can be mounted on a DIN rail or 19" mounting profiles.
Technical Specifications
- Supply: 230 V, 50 Hz
- Current: 0.5 A
- Insulation Class: 2nd
- Protection Class: IP-52
- Max Ambient Temperature: 40 °C
- Thermal Insulation Class: B (130 °C)
PWS2 Roof Fan
The PWS2 fan is designed for installation in standard 380 x 380 mm holes in various cabinet models. It can be connected directly to the AC grid or via a speed controller. The fan is equipped with a steel grille and can optionally include a discharge stack for air duct connections.
Design and Control
- Made of RAL 9005 sheet steel
- Single-phase asynchronous motor with thermal protection
- Compatible with KTS thermostat, ARO 0.6 speed controller, MPSK G0 microprocessor panel, and MPSM-S1 microprocessor power control panel
Technical Specifications
- Supply: 230 V, 50 Hz
- Power: 0.088 kW
- Max Speed: 1350 RPM
- Efficiency: 3600 m3/h
- Compression: 58 Pa
- Noise: 64 dB
- Ambient Humidity: 20-85%
- Temperature Range: -20 to +80 °C
- Motor Protection Class: IP 44
- Body Protection Class: IP 20

Performance and Noise
The PWS2 fan emits significantly less noise and consumes up to 60% less energy compared to the PWD-4W panel. Noise levels can be reduced by adjusting the fan speed, making it suitable for office environments. The fan's noise emission increases logarithmically, with a 1 dB increase equating to a 26% increase in noise.
Conclusion
The PWS2 roof fan and ARO 0.6 speed controller offer efficient and quiet ventilation solutions for cabinets, with flexible control options and compliance with relevant standards.
Catalog excerpts
Ventilation systems PWS2 ARO 0.6 speed controller ARO 0.6 autotransformer controller is used to manually adjust speed of the PWS2 fan. It has 2nd insulation class and IP-52 protection class, max. ambient temperature is 40 °C, whereas thermal insulation class B (130 °C). It has five-step transformer speed control so you can adjust the fan speed and also the noise generated by the PWS2 fan. The first 4 control steps are designed to achieve a compromise between performance and noise, while with the 5th step you can make use of fan’s full power. The controller is very well matched to supply network and the fan (no adverse impact on the grid). It has a resettable thermal switch (90 °C). Made in line with PN-EN 61558-2-13. To be mounted on a mounting plate or on the DIN rail. The controller can be mounted on 19" mounting profiles with PS-3U panel (see ZPAS Group product catalogue 2014, page 156; not included in the controller’s scope of delivery).
