EASY MOUNTING NO DRAFTS RELIABLE PROTECTION
The telescopic air duct provides simple installation. The protective air shutters prevent backflow. The outer hood protects the ventilator from direct ingress of water and large foreign objects.
 
Easy manual control. The filters clean the supply air protecting it from dust and insects. Several ventilators can be controlled by one control panel.
EASY CONTROL
  • The ventilator is operated by the KVR control panel or the KVR-T 12 (230/12) control and power unit.
  • The KVR-T 12 (230/12) control and power unit with power of 12 W is included in the delivery set of the TwinFresh RA-50-14 ventilator and comprises the KVR control panel and the TRF 220/12-12 transformer under one casing.
  • The TRF 220/12-12 transformer with power of 12 W can supply power to up to 4 ventilators.
  • The TRF 220/12-40 transformer with power of 40 W can supply power to up to 11 ventilators.
  • The KVR panel is not equipped with a power supply unit and is designed for mounting with a TRF transformer.
  • Operation modes:
  1. Ventilation mode  (extract or supply) at Speed I.
  2. Ventilation mode  (extract or supply) at Speed II.
  3. Reversible operation mode  (regeneration) at Speed I.
  4. Reversible operation mode  (regeneration) at Speed II.
ADVANTAGES
Simple control – by a button switch. No sensors, timers and automation. Many ventilators can be connected to one network.
Ventilation of premises with the area of about 40 m2 (the area is approximate and depends on the ventilation standards in your country). Normal operation at temperatures up to -20 °C.
Noise at the level of human whisper (14-24 dBA). Automatic drafts shutoff by automatic shutters when the ventilatoris is off.
