10+ year parts supply

Airflow Range ~450 m³/h rated Adjustable via variable-speed EC motor. Typical residential range: 120–350 m³/h. C5 humidity control auto-adjusts.

Heat Recovery Efficiency 81% Enthalpy core. Passivhaus certified. Heat and moisture both recovered from exhaust air.

Specific Electric Power (SEP) 0.38 Wh/m³ EC motor. ErP 2018 A++ energy class. Ultra-low running cost — ~£20–25/year at normal residential use.

Sound Pressure Level 15 dB (low speed) | 18 dB (high) Very quiet at low/medium speed. Horizontal orientation aids acoustic damping.

Filter Stages F7 activated-carbon (supply, standard) "F" designates F7 supply filter as standard. Recommended for urban environments, London, and pollution-sensitive areas. Extract: G4 dust.

Installation Type Horizontal ceiling mount "CF" = ceiling-floor orientation. Duct connections on top and sides. Ideal for new-build and retrofit projects with accessible ceiling voids. Unit footprint ~1200 × 600 mm.

Control Variant C5 Humidity sensor with basic demand control. No Modbus (see Domekt R series for building automation). Simple wall-mounted 3-speed selector.

Building Coverage ~300–500 m² Suitable for 3–4 bedroom homes and small multi-unit residential. Actual airflow depends on duct design and extraction geometry.

Humidity-demand control

Built-in sensor adjusts motor speed automatically. Ramping: low speed at <40% RH, medium at 40–60%, high at >60%. Reduces unnecessary fan runtime in dry conditions.

Manual override

Wall-mounted 3-speed selector. Boost function for peak demand (e.g. cooking, showering). C5 remembers speed preference after override timer expires.

Summer bypass damper

Manual or thermostatic. When outdoor air is warmer than indoor, damper opens to bypass the heat exchanger. Fresh air enters without cooling from the core.

No Modbus option

C5 is a simpler control variant — suitable for residential new-build. For building automation and remote monitoring, upgrade to Domekt R series (C6M with Modbus RS-485).

01 Location Suspended ceiling void, loft above insulation, or accessible basement ceiling. Unit lies horizontally. Height clearance required: ~400 mm above and below the unit for inspection and filter access.

02 Duct connections Top-mounted or side-mounted ducts depending on ceiling void geometry. Supply air delivered to bedrooms, living areas via grilles. Extract from kitchen, bathrooms, utility areas.

03 Electrical 230 V, single-phase. Low power draw (~80–100 W at mid-speed). Standard household circuit. Control wiring for humidity sensor.

04 Fit day process Phone consultation → fit day (unit mounted, ductwork integrated, controls tested) → use walkthrough. No separate site survey — engineer checks conditions on fit day.

Supply-side Filter F7 activated carbon (standard, "F" variant) F7 is the default for Verso CF 1000 F C5. Filters dust, pollen, PM2.5, and odours. Recommended for all urban and suburban locations.

Extract-side Filter G4 dust Protects the enthalpy core from lint and kitchen grease. Change every 6–12 months depending on cooking and occupancy.

Filter Change Interval 6–12 months typical EC motor load increases visibly when filters clog. Visual inspection hatches on the unit show condition. Low-speed operation may indicate supply-side blockage.

Parts Availability 10+ year guarantee Komfovent maintains parts stock across active models. Filter cartridges, sensor units, and control boards available from CleverBloom or Komfovent directly.
