Description of the power roof ventilator Range of Application The MIRUVENT is an extract air fan, designed for use in most extract air systems in comfort ventilation systems, in which the air has a low content of impurities. The power roof ventilator should preferably be mounted on an LBFT roof penetration collar. This provides a fire-resistant and sound-absorbent extraction passage through the roof and a tight connection to the extract air duct. As an alternative the power roof ventilator can be mounted on an existing roof penetration collar across a TBFS connection fitting. Closed, discretely...

Description of the power roof ventilator Installation Examples 1. Outlet openings covered with self-opening and selfclosing airstream-operated dampers (standard) as protection against bad weather when the fan is idle. The airstream-operated dampers also counteract cold down draughts and heat loss. 2. MIRUVENT power roof ventilator 3. TBFT roof penetration collar including TBFS connection fitting 4. 50 mm thick insulation conforming to the provisions of Fire-resistance Class EI 30 alt. EI 60, internally lined with perforated sheet steel. 6. Structural panel (not supplied by Swegon). 7. Roofing...

Description of the control equipment Control equipment The MIRUVENT power roof ventilator can be controlled in several different ways. All the fans are as standard equipped with safety isolating switch that can be switched from the outside of the fan. The electrical connections for the fan are also wired there. MIRUVENT is equipped with a motor for single-speed operation and can be supplemented with a control system for variable speed regulation. External equipment The MIRUVENT units with AC motors can be equipped with external control equipment for starting and stopping the fan consisting of...

Description of the MIRU Control functions Time/Date, time switch clock The current date and time can be set and adjusted if needed. The Time switch clock (timer) automatically takes leap years into consideration. Flow regulation (control) Flow regulation involves operating the power roof ventilator to keep the preset airflow constant. The power roof ventilator fan speed is automatically regulated to provide correct airflow. The system is preset for automatic changeover between summer time/winter time according to EU Standard. It is possible to block this changeover. Weekly program/Time schedules...

Description of the MIRU Control functions Energy status The SFP value, current power output, energy consumption for the most recent seven or thirty days and total energy consumption since the start can be read on the screen. Temperature compensation Temperature compensation of the airflow can be activated if it is desirable to displace the airflow as a function of the outdoor air temperature or the room air temperature. In the pressure regulation mode, the current setpoint for airflow is offset. In the pressure regulation mode, the current setpoint for pressure is offset. The current temperature...
