Talks to your BMS or home automation
Modbus RS-485 as standard
Stale, humid air is drawn continuously from the kitchen, bathrooms, en-suites and utility room through Ø160 mm ducts back to the unit — carrying moisture, cooking smells and CO₂ out of the house.
A slowly turning aluminium rotor passes alternately through the warm extract stream and the cold incoming stream, carrying heat — and moisture — from one to the other. Up to 86% of the heat is retained.
Incoming outdoor air passes an ePM1 60% (F7) cartridge, capturing the fine PM1 and PM2.5 fraction from traffic along with pollen and dust. Extract air passes an ePM10 50% (M5) filter that protects the rotor.
Pre-warmed, filtered fresh air is delivered to bedrooms and living rooms through spiral ductwork and ceiling or wall valves, balanced against the extract rate at commissioning.
When outdoor air is cooler than indoor, the C6M stops the rotor. Air passes straight through without heat transfer — night cooling for the cost of the fans alone. Rotary units need no bypass damper.
In cold weather an integrated electric pre-heater and rotor speed modulation keep the exchanger clear without shutting down supply air — so an airtight house is never left depressurised by extract-only running.
C6M controller. Eight preset modes with weekly scheduling as standard; demand control added by fitting an optional humidity or CO₂ sensor. Wall panel ordered separately.
8 preset modes
Away, Normal, Intensive and Boost, each with its own supply and extract setpoints.
Weekly scheduling
Day-by-day programme so the house ventilates to occupancy rather than running flat out.
Air-quality control
Optional humidity or CO₂ sensor on the C6M's air-quality input drives fan speed automatically.
External override inputs
Kitchen, Fireplace and Override modes triggered from switches — boost while cooking, reverts on timer.
0–10 V intensity input
A separate 0–10 V signal can set ventilation intensity where a third-party controller drives the system.
Modbus RS-485
Standard. BMS, home automation and landlord monitoring — airflow, fan speed, filter status, temperatures.
Web browser interface
Full settings and diagnostics from a browser on the local network, no app required.
Komfovent Control app
iOS and Android. Mode selection, scheduling and alarms from the phone.
C6.1 / C6.2 panel
Wall-mounted control panel, ordered separately. C6.2 adds the larger colour display.
A single insulated vertical cabinet holding the rotor, two EC fans, both filters, the pre-heater and the C6M board. All five duct connections leave the top face.
Rotary heat exchanger
Aluminium rotor, up to 86% thermal efficiency. Transfers heat and moisture without the air streams mixing.
Two EC fans
Independent supply and extract, variable speed. 55 W combined at reference flow, 147 W at maximum.
Supply filter
ePM1 60% (F7) cartridge, 517 × 278 × 46 mm. The grade to specify for London and traffic corridors.
Extract filter
ePM10 50% (M5), same cartridge size. Protects the rotor from lint and kitchen grease.
Electric pre-heater
Integrated. Handles rotor frost protection in cold weather — no separate frost coil to specify.
C6M control board
Modbus RS-485, air-quality sensor input, 0–10 V input and external override terminals on board.
Duct connections
4 × Ø160 mm and 1 × Ø125 mm, all on the top face. Left- or right-hand configuration set at order.
Cabinet
585 × 655 × 680 mm insulated casing. Allow 700 mm clear in front for filter and rotor access.
Weight
60 kg — floor-standing on a level, load-bearing base. This is not a wall-hung unit.
The only routine task is changing two filter cartridges. There is no condensate trap to clear and no refrigerant circuit to service.
3 year warranty
Komfovent covers the unit for 3 years. Manufactured in Lithuania under an ISO 9001 quality system.
Filter changes
Two cartridges, every 6–12 months depending on location, cooking and occupancy. Slide out, drop in, done.
Filter alarm
The C6M tracks running hours and raises a filter alarm. Fan power on the controller rises as cartridges load — an earlier warning still.
Rotor drive
A single drive belt is the only wearing part in the exchanger. Checked at each filter change, replaced in minutes.
Remote diagnostics
Over Modbus, the web interface or the app: airflow, fan speed, filter status and temperatures — most faults diagnosed without a site visit.
Parts availability
Komfovent holds stock across current Domekt models — filter sets, drive belts, sensors and control boards.
