CV (CityVent) Air Handling Units for apartments

Improved levels of insulation and draught proofing have created the need for efficient ventilation in the home. Not only is this necessary for good indoor air quality, but also for the removal of condensation and airborne contaminants.

SAV Systems’ CityVent air handling units with demand controlled ventilation are designed for home applications and tick all the boxes when it comes to ease of use and energy efficiency. The CV 80 and CV 200 units offer a large choice of duct connections; CV 80 offers 18 different combinations, the CV 200 offers 12. This means that a huge variety of apartment layouts can be accommodated with minimal adjustment. It makes the architect’s job of accommodating internal ductwork considerably easier and helps to avoid ductwork crossover.

Long term performance is excellent, due to robust construction and high quality filtration. CityVent air handling units fit neatly into ceiling voids (280mm height for the CV 80, for example) and provide reliable whole-of-house ventilation through a system of supply and extract ductwork.

Casing breakout noise is limited to just 30dB(A) at 1m, which means that units can be located anywhere in the apartment ceiling void without fear of creating noise nuisance. In-duct noise will need appropriate attenuation measures, such as acoustic protection of ductwork and in-line attenuators.

City Vent units are provided with bottom access panels, which can easily be opened to gain access for filter replacement. In some cases, the architect has chosen to set the access panel at the same level as the suspended ceiling, which makes for the simplest possible access!

CV units are available in 3 sizes, all of which have a remarkably low noise profile:

CityVent CV 80 Air Handling Units

80 m³/hr at 40 Pa external Δp, producing just 30 dB(A) @1m.

This air handling unit with reduced energy consumption and low sound pressure is designed for small apartments of up to 50 m² floor area.

This floor plan shows a pair of 1-Bedroom apartments, where a CV 80 heat recovery unit has been installed above the bathroom ceiling in each apartment.  CV 80 air handling units offer many arrangements for the intake, exhaust, inlet and extract duct connections, enabling good layout choices to be made regardless of apartment layout.

CityVent CV 200 Air Handling Units

200 m³/hr at 100 Pa external Δp, producing 30 dB(A) @ 1m. 

The CV 200 can take care of the ventilation needs of houses or large apartments of up to 150 m² floor area.

CityVent CV 200 Air Handling Units

2-Bedroom Apartments


These CV 200 air handling unit arrangements show ventilation supply to bedrooms / living room, with extraction from kitchen / bathroom.  Connection to CV 200 heat recovery units can be made in any of 12 different combinations.

CityVent DV 1000 Air Handling Units

1,000 m³/hr at 100 Pa external Δp, producing 36 dB(A) @ 1m.

This highly efficient unit with balanced air flow is good for public buildings and office development with floor areas of over 150 m². It can also be useful in blocks of flats, for the simultaneous ventilation of up to 6 apartments.

Energy efficient fans and drive motors mean that specific fan power is kept low (<1,000 W/m³/s). In the event of high indoor room temperature, the bypass damper to the heat exchanger opens to allow a proportion of external air to arrive without being heated. No manual intervention is required, as the bypass modulates automatically. This feature comes as standard.

During summer periods, night cooling can be a valuable aid to temperature control. In this mode, a unit continues to run during night hours so that the room surfaces and furnishings are cooled, giving the rooms a fresh feel to start the following day.

Better Humidity Control with Air Handling Units

Proper control of humidity is seen as vital to providing a comfortable indoor environment. To help with this, SAV’s CV air handling units are provided with external and internal humidistats, placed in the ducting for fresh air intake and extract pathways respectively. This means that the control system remains aware of the differencebetween internal and external humidity. If this difference were small, ventilation flow would be automatically decreased. Conversely, if internal humidity were to rise and create an increased differential, ventilation rates would increase.

To deal with condensate disposal issues, a condensate pump is fitted as standard.

CityVent units are compact, efficient and unobtrusive. They have the potential to revolutionise the ventilation of modern apartments, maintaining good indoor air quality with excellent humidity control over long periods of service. The sheer choice of available duct configurations will give your architect and internal designer a great deal of freedom when preparing the plan views of apartments.
