Fresh air, air distribution & central vacuum — answered

A fresh air ventilation system brings outdoor air into a building and helps remove stale indoor air. The design and filtration depend on the property, occupancy, outdoor conditions, and selected equipment.

An Energy Recovery Ventilator (ERV) exchanges heat and some moisture between outgoing and incoming air. This can help reduce the energy impact of ventilation. Actual performance depends on the system and operating conditions.

An air purifier filters air already inside a room. An ERV is designed to ventilate by exchanging indoor and outdoor air, and may also filter incoming air depending on its configuration. They serve different purposes.

An ERV can be designed to operate alongside air conditioning. The equipment, airflow, controls, and installation should be selected for the building and its HVAC setup.

It may be possible, depending on the available ceiling or service space, the route for ducts, and the building layout. Benvek can review the floor plan and site conditions to advise on options.

The counter-flow graphene enthalpy recovery core transfers coolness and dryness from the outgoing room air to the incoming outdoor air without the two streams mixing — manufacturer-rated above 80% (86–97% depending on model, per the MC-GN booklet). Fresh air enters close to room temperature, limiting the added load on your AC. Actual impact depends on climate, sizing and operating conditions.

The multi-stage filter stack (washable G4 pre-filter, activated carbon, high-efficiency HEPA) is designed for Indian urban conditions, and balanced positive pressure helps keep smoky air from leaking in through gaps. Indoor PM2.5 outcomes depend on sizing, runtime and how sealed the space is — component ratings are listed in the evidence table on this page.

The pre-filter is washable. Cartridge life varies with outdoor air quality, and supported smart controllers flag when replacement is due. The graphene recovery core is described in the booklet as anti-mold with a long service life given periodic dry vacuuming. Filter care is available under Benvek AMC.

Air distribution design helps determine how conditioned or ventilated air reaches different rooms. Duct routing, outlet locations, airflow requirements, and noise considerations should be planned for the specific property.

Ideally, discuss the layout during the design or construction-planning stage, before ceilings are closed. Early coordination can make it easier to plan duct routes with other building services.

Yes. Share the available floor plan and project details with Benvek. The team can review the information and advise what additional measurements or engineering assessment may be needed.

Standard axial wall fans lose suction once duct length grows. The recommended approach mounts high-static mixed-flow inline fans and heat-resistant metal-impeller puja extractors above the false ceiling, leaving only a silent architectural slot or flush panel visible in the room; exact hardware is specified per project.

A central vacuum system uses inlets in different parts of a building connected through concealed piping to a central power unit. The equipment and layout are selected based on the property and installation requirements.

A portable vacuum is carried from room to room. A central vacuum system uses fixed inlets connected to a central unit, so the user connects a hose at the inlet instead of moving the main machine around.

Possibly. Feasibility depends on the building layout and whether suitable routes are available for the piping. A site review is needed before confirming an installation plan.

Wall inlet valves can be fitted with a tight trap-elbow right behind the faceplate, so a rigid object larger than the pipe bend is caught at the inlet itself and cannot enter the main concealed PVC line.

Both kinds exist. Wet & dry models pick up liquid spills, while dry-only systems and retractable in-wall hoses are for dry dust. The choice of power unit decides this - mention it when you enquire.

Compact residential units (CVAC Eco range and the fully automatic model) run on standard 230 V single-phase supply. Larger commercial units (CVAC 3.0 and 5.0) need 415 V three-phase. Electrical provision is checked at the layout stage.

The power unit sits in the utility, balcony or garage, so the room hears mostly airflow at the hose. Units on the Central Vacuum page carry published sound levels of 70-72 dB measured at the machine; what you hear depends on the unit, its placement and the installation.

It depends on the floor plan: each wall inlet serves the area its hose can reach, and retractable-hose points cover a larger radius from fewer locations. Share your floor plan and inlet positions can be marked on it.

For concealed ducted ERV, inline exhausts and central vacuum piping (Stage A), involve us right after brick/masonry work and before false-ceiling or flooring closure. For occupied homes (Stage B), ductless wall/floor ERVs and spot ceiling extractors can be retrofitted without breaking ceilings.

Yes. Once you share your AutoCAD/PDF floor plan, our MEP engineers prepare coordinated ducting, beam-crosser and vacuum pipe drawings and work directly with your architect, interior designer and VRV/VRF AC contractor.
