What are air distribution products (ADP)?
Air distribution and ventilation products include extractor fans, inline and cabinet fans, filter boxes, ducts, diffusers, valves and exterior vents. These components move, filter and direct air as part of a planned system. Benvek helps select products for the airflow, duct resistance and installation space of each project.

INSTALLATION, COST & CARE
Choose ventilation fans, ducts and diffusers together
Bathroom exhaust and inline duct fans
Select a fan for the airflow and resistance of its complete route. Coordinate inlet and outlet positions, duct size and acoustic requirements. The fan format should suit the available mounting space and access for inspection.
Air distribution installation and cost factors
Fan selection, filtration, duct construction, route length, room-terminal count and controls all influence the quotation. Coordinate the layout with ERV or HVAC equipment and confirm what the supply and installation scope includes.
Access for ventilation maintenance
Plan inspection access for fans, filter boxes and duct components. Keep room terminals accessible. Use the equipment manufacturer’s care instructions and agree on servicing requirements for the building’s use and operating conditions.
QUESTIONS BEFORE YOU PLANDiscuss your project with Benvek →
Practical answers for your project
What is the difference between a bathroom exhaust fan and an inline duct fan?
A bathroom exhaust fan extracts air from the room at its installed position. An inline duct fan is fitted within a duct route. The suitable arrangement depends on the airflow, duct resistance, noise target and available space.
What affects the cost of air distribution installation?
The quotation depends on the selected fans and filters, duct type and length, number of diffusers, controls, access and installation work. A coordinated layout allows Benvek to identify the equipment and site-work scope.
How are ventilation ducts, fans and diffusers maintained?
Provide access for inspection and follow the selected equipment’s care instructions. Inspect accessible terminals, fans and filter housings as appropriate to the application. Filter service and duct cleaning requirements depend on the system and site conditions.
How do I choose a ventilation fan or diffuser?
Selection depends on required airflow, duct resistance, room use, available space and noise targets. Fan capacity and terminal size should be selected together with the duct layout.
Can air distribution products be used with ERV and HVAC systems?
Yes. Fans, filter boxes, ducts, valves and room terminals are coordinated with ERV and HVAC designs for homes, offices, shops, schools, coffee shops and other project types.
Does every exhaust fan work for kitchen grease extraction?
No. Kitchen grease extraction requires fans, filters and ductwork designed for that purpose. Confirm the cooking application and ventilation specification before selecting equipment.
