Why FlowPLUS-R

6 modular speed settings

Night (8) → Standard (10/17/26/37) → Hyper (42) m³/h.

91% peak heat recovery

Enthalpy exchanges heat and moisture. Best-in-class.

Radon mitigation built-in

Reversible operation creates pressure to prevent radon entry.

Smart app control

Helty Home app. Monitor, schedule, adjust remotely.

Night function

17.5 dB(A) — silent during sleep hours.

Hyperventilation boost

42 m³/h peak for fast moisture removal.

Free-cooling summer mode

Delivers cooler outdoor air when beneficial.

Retrofit, one-hour install

Two 80mm wall cores. No ducts. Perfect for flats.

Extract

Warm, stale, humid air is drawn out of the room continuously and gently.

Recover

The enthalpy core transfers up to 91% of the heat — and moisture — to the incoming stream.

Supply

Filtered fresh outdoor air enters already tempered, so the room stays warm and comfortable.

Reverse (radon)

The -R variant can reverse airflow to create positive pressure that keeps radon gas out.

Coverage 25 m² Sized for single rooms of roughly 15–25 m² — bedrooms, home offices and living rooms. One unit per room; no ducting between spaces.

Airflow 42 m³/h Six selectable stages from 8 to 42 m³/h — night, four standard steps, and a hyperventilation boost for fast moisture removal after showers or cooking.

Heat Recovery 91% Enthalpy counter-flow exchanger recovers up to 91% of the heat and, uniquely, moisture too — keeping rooms warm and humidity balanced. Efficiency ranges 91% down to 68% at full boost.

Acoustic 17.5 dB(A) 17.5 dB(A) sound pressure in night mode — effectively silent while you sleep. Rises to 42.2 dB(A) only at the hyperventilation boost.

Radon Reversible The -R reversible operation creates pressure balance that keeps radon gas out. Add an optional radon sensor to trigger it automatically as levels rise.

Control App + IR Helty Home App over WiFi for schedules and remote adjustment, plus an included IR remote and on-unit LED panel. Free-cooling/free-heating and CO₂/IAQ sensor compatibility built in.

Filtration F7 + G4 / G2 Intake ePM2.5 65% (F7) plus Coarse 90% (G4); extract Coarse 70% (G2). Captures pollen, fine dust and PM2.5. The panel flags filter changes automatically.

Electrical 2–20 W 230 V single-phase, 50 Hz. Just 2–20 W across the six speeds, 0.15 A max current. Runs on a standard socket circuit — no special supply needed.

Dimensions 339×467×144 339 × 467 × 144 mm (W × H × D), 8 kg. Two Ø80 mm wall cores, no ductwork, fitted in under an hour. Mounts horizontally or vertically.

Energy A+ Energy efficiency class A+/A/E across cold, temperate and warm climates. SEC -74.1 / -37.9 / -14.6 kWh/m²a.

Certification EN 13141-8 Tested and certified to UNI EN 13141-8, the European standard for the performance of ductless dual-flow room ventilation units. Order code 1VMC02034.

Helty Home App

Set speeds and schedules, watch status, and switch modes from anywhere. Multi-unit management supported.

IR remote + panel

Battery IR remote and on-unit LED panel for on/off and speed — no phone required for day-to-day use.

Free-cooling / free-heating

Automatically draws in cooler or warmer outdoor air when it benefits the room, bypassing recovery.

CO₂ / IAQ sensors

Compatible external air-quality sensors auto-boost airflow when CO₂ or pollutants rise.

Radon sensor

Add a radon monitor to trigger reversible operation automatically when levels climb.

Modbus RTU rs485

Wire into a building management system for centralised control across multiple units.

01 Phone chat Room size, radon test result, WiFi coverage area.

02 Fit day Engineer drills cores, mounts unit, WiFi pairing. 45–60 mins.

03 How-to-use Remote demo. Helty Home app setup. Speed recommendations.

04 No survey day All checks done at fit appointment.
