Household ventilators provide the controlled mechanical air extraction required to remove moisture, odours and pollutants from residential properties — preventing the condensation, mould growth and indoor air quality problems that arise when natural ventilation alone is inadequate. The standard residential application categories are bathroom and shower room extraction (100mm and 120mm wall and ceiling fans removing humidity at source after showering), kitchen extraction (150mm and larger fans removing cooking odours and steam), utility room and WC extraction (compact axial fans for low-airflow continuous or intermittent use), inline duct ventilation (concealed in-line fans serving multiple extract points through ducted systems), and whole-house MVHR systems (Mechanical Ventilation with Heat Recovery — continuous balanced ventilation for energy-efficient new builds and renovations).
DAS Company is an authorised Cata distributor and supplies a wide range of household ventilation products from leading European manufacturers — Cata, Vortice, S&P, Vents and other recognised brands — to electrical contractors, plumbing and heating installers, property developers and facilities managers across Europe. All products carry CE marking and ErP (Energy-related Products) compliance with Regulation (EU) No 1253/2014 — the regulatory baseline for residential ventilation products sold and installed in EU member states.
The 100mm silent bathroom extractor fan is the highest-volume product in the household ventilation category — installed in virtually every bathroom and shower room in new-build and renovation residential projects across Europe. Standard 100mm axial fans deliver typical airflow rates of 85–95 m³/h at noise levels of 26–35 dB(A) — sufficient to remove humid bathroom air at the rate required to prevent condensation and meet residential ventilation building regulations across most EU member states. The IP45 splash-proof rating standard on quality bathroom fans permits installation in Zones 1 and 2 of the bathroom (proximity to shower and bath), with selected models carrying IP44 or IP45 for direct installation in shower enclosure zones.
Common bathroom fan feature variants address specific installation requirements. Standard switched fans operate from the bathroom light switch — coming on with the light and remaining on for an adjustable timer period (typically 1–30 minutes) after the light is turned off, allowing humidity to clear after bathroom use. Humidity sensor variants add a humidistat that triggers fan operation when relative humidity exceeds a setpoint (typically 65–75%) regardless of light switch state — automatically responding to shower steam and longer-duration humidity events that exceed the standard timer setting. PIR (presence detection) variants trigger fan operation when bathroom occupancy is detected — preventing unnecessary fan operation when the light is left on without bathroom use. Pull-cord variants for retrofit installation where wiring to a wall switch is impractical. Premium silent fans feature backdraught shutters (integrated dampers that close when the fan stops) preventing cold air ingress from the duct termination point — important in cold climates where reverse airflow through stopped fans causes condensation and heat loss.
Kitchen extractor fans address the higher airflow and grease/steam loading of cooking ventilation — typically requiring 150mm or larger duct connection and 200–500 m³/h airflow depending on the kitchen size and cooking intensity. Centrifugal kitchen fans are preferred over axial designs for ducted kitchen extraction because centrifugal fans generate higher pressure — necessary to overcome the airflow resistance of longer duct runs from kitchen to external wall termination through ceiling voids and roof spaces, which axial fans cannot overcome efficiently. Kitchen-specific fans include grease-resistant motor construction and easy-clean fan blade access — addressing the kitchen-specific maintenance requirements that bathroom fans are not designed for. Window-mounted kitchen fans (Vortice Vario series and equivalent) install directly through external glazing or wall — providing extract ventilation without ceiling-void ducting in kitchens where a route to external wall is direct and unobstructed. Variable speed control (2-speed or 3-speed) allows the user to match airflow to cooking activity — full speed for active cooking, low speed for residual odour clearance and continuous background ventilation.
Inline duct fans mount within the ductwork between the extract grille and the external termination — concealed in ceiling voids, loft spaces or service ducts rather than visible in the room. Inline installation provides two distinct advantages over room-mounted fans: reduced noise in the served room (fan motor is physically distant from the occupied space, with ductwork providing acoustic isolation) and single-fan multi-room operation (one inline fan can serve multiple extract points — bathroom, ensuite and WC — through branched ducting with individual room grilles). Axial flow fans for in-line installation, diameters between 100 and 150 mm, with or without timer, air flows from 65 m³/h to 320 m³/h, suitable for ventilation of dwellings with air extracted directly to the outside or along ducts of limited length. Mixed-flow inline fans (combining axial and centrifugal characteristics) provide higher static pressure than pure axial designs — appropriate for installations with longer duct runs, multiple bends or extended termination distances where pure axial inline fans cannot generate sufficient pressure to maintain airflow.
dMEV (decentralised Mechanical Extract Ventilation) is the current standard approach to residential ventilation in energy-efficient new builds and renovations — replacing intermittent on-off fan operation with continuous low-rate background extraction that automatically boosts to higher rates when humidity or occupancy demands. The dMEV fan runs continuously at low speed (typically 8–15 m³/h, near silent operation below 20 dB(A)) — providing the constant background ventilation required to maintain indoor air quality without the energy waste of continuous high-rate extraction. Intelligent humidity boost automatically increases airflow when humidity rises above threshold (after showering, cooking or other moisture events) — providing the high-rate extraction precisely when it is needed without operator intervention. PIR boost increases airflow when room occupancy is detected, ensuring adequate ventilation during room use and reducing energy consumption when unoccupied. dMEV fans meet the continuous ventilation requirements of EN 15665 (residential ventilation system specification) and qualify for the highest ErP energy efficiency classes — making them the preferred specification for new-build residential developments targeting EPC A and B energy ratings.
MVHR systems provide the highest-performance residential ventilation specification — continuous balanced extract and supply ventilation through a heat exchanger that recovers 80–95% of the heat from extracted air, transferring it to incoming fresh air without mixing the air streams. MVHR is the standard specification for Passivhaus-certified residential buildings and is increasingly specified for new-build residential developments targeting near-zero energy building (nZEB) compliance under the EU Energy Performance of Buildings Directive. An MVHR system serves the complete dwelling — extracting from bathroom, kitchen, utility and WC simultaneously through dedicated extract duct network, supplying fresh tempered air to bedrooms and living rooms through dedicated supply duct network, and using the central MVHR unit's heat exchanger to recover heat from the extracted air before exhaust. MVHR systems comply with EN 13141-7 (performance testing of mechanical supply and exhaust ventilation units for residential buildings) and provide documented heat recovery efficiency for SAP energy assessment and EPC certification. DAS Company supplies MVHR systems and the associated ducting, attenuators and air valves alongside dMEV and conventional extract fan equipment — providing the complete residential ventilation supply for property developers and renovation contractors.

Cata bathroom fans are particularly recognised for their cost-effective entry-level positioning at competitive price points relative to premium Italian and German brand equivalents — making them the preferred specification for housing developer projects where ventilation specification meets building regulations at the most efficient project cost. DAS Company is an authorised Cata distributor for Eastern Europe — supplying the complete Cata residential ventilation range to electrical and HVAC contractors, housing developers and property managers across the region with volume pricing for new-build residential development supply.
Vortice is the European market leader in residential ventilation — manufacturing premium-design and high-performance fans from the company's Milan, Italy production base since 1954. Vortice's residential range covers axial and centrifugal extract fans (Punto, Quadro, Notus, Lineo series), in-line ducted fans, window-mounted ventilation and complete MVHR heat recovery systems. The Vortice Lineo Quiet ES sound-proof energy saving mixed-flow extractor fans address the increasing residential preference for near-silent ventilation operation that does not interfere with sleep or quiet daytime activities. Vortice premium positioning provides design-led aesthetics for visible installations in premium residential interiors — the Quadro range in particular is widely specified for architect-led residential projects where bathroom fan appearance matters alongside performance. DAS Company supplies the Vortice residential range alongside Cata and other ventilation brands — providing premium and value-positioned alternatives across the residential ventilation specification range.
The correct household ventilator specification depends on five factors: the served room type and size (which determines required airflow rate), the duct length and configuration (which determines required static pressure capability), the operating mode (intermittent after switch, continuous background with boost, or continuous balanced with heat recovery), the noise requirement (which determines premium silent fan specification vs cost-effective standard fan), and the building regulation requirement (which mandates minimum airflow rates and energy efficiency compliance). Typical application matches: standard bathroom (5–7 m²) requires a 100mm fan at 90 m³/h with timer; en-suite or larger bathroom (8–12 m²) requires a 120mm fan at 150 m³/h with humidity sensor; kitchen (10–15 m²) requires a 150mm centrifugal fan at 300–500 m³/h; multi-room ducted (bathroom + ensuite + WC) requires an inline mixed-flow fan at 200–300 m³/h serving three branched extract points; whole-house high-efficiency (new build) requires a complete MVHR system sized to the dwelling floor area.
