Fresh Air Fan & Makeup Air Unit Supplier in Saudi Arabia
Fresh air and makeup air fans for commercial kitchens, mechanical rooms, warehouses, roof supply systems, and project ventilation balance.
What is a fresh air fan and when is makeup air required?
A fresh air fan supplies outdoor air into a building, kitchen, mechanical room, warehouse, or commercial ventilation system. They are different from exhaust fans because the main purpose is to bring air in, not remove air out.
In Saudi Arabia projects, fresh air and makeup air selection is important when exhaust systems remove large airflow. Commercial kitchens, factories, warehouses, and mechanical rooms may need controlled supply air to reduce negative pressure, improve hood capture, support equipment rooms, and balance the ventilation system.
Fresh Air Fan Products
Choose a fresh air or makeup air product based on where air enters, whether filtration is needed, how much exhaust air must be replaced, and the available roof, wall, or duct opening.

|---|---|---|---|---|---|
| Kitchen Makeup Air Unit | Commercial kitchens with hood exhaust systems | Outdoor air supplied through a roof or ducted supply unit toward the kitchen or adjacent replacement-air zone | Cooling, heating, dehumidification, filtration, and exact supply-air percentage are not automatic; they depend on the selected configuration and mechanical design | Hood and exhaust CFM, required supply CFM, static pressure, intake location, filters or tempering, voltage, controls, quantity, and project city | View |
| RMUA Roof / Wall Fresh Air Supply Fan | Mechanical rooms, warehouses, substations, and roof or exterior wall fresh air introduction | Direct-drive axial outdoor air supply discharged downward through roof curb or wall opening | General clean-air building supply only; does not include grease filtration, cooling, or smoke-rated construction | Model (RMUA-14/18), operating CFM at external SP, roof curb vs wall mounting, damper, 220V 60Hz, project city | View |

Common project applications
What to send before quotation
Engineering & Application Safety Notice
Fresh-air equipment does not automatically provide cooling, heating, dehumidification, filtration, smoke control, or code compliance. Intake location, outdoor-air quality, filters, temperature and humidity treatment, system pressurization, fire/smoke dampers, and control interlocks must be confirmed against the mechanical design, consultant requirements, and applicable project codes.
Project accessories and procurement support
Accessories and documents depend on the selected model, installation condition, consultant requirement, and project approval workflow.
Fresh Air Fan support for Saudi projects
Share the project city during quotation so product availability, delivery direction, and documentation needs can be reviewed for your Saudi Arabia project.
Common fresh air fan questions
Short answers for contractors, MEP teams, procurement buyers, and facility teams preparing a quotation request.
What is a fresh air fan used for?
Fresh air fans supply outdoor air into a building or room. They are used for makeup air, pressure balance, mechanical rooms, and general ventilation support.
Why is makeup air important for kitchen exhaust?
When a kitchen hood removes large airflow, replacement air is needed to reduce negative pressure, door issues, poor hood capture, and uncomfortable indoor conditions.
How much makeup air is required for a kitchen exhaust system?
The required makeup airflow must be calculated as part of the approved kitchen and mechanical ventilation design. It depends on hood exhaust CFM, transfer air from adjacent spaces, pressure targets, supply-air location, comfort conditions, and project requirements; a single percentage should not be applied to every kitchen.
Should fresh air be filtered or cooled in Saudi Arabia?
Filtration and air treatment depend on outdoor dust conditions, indoor comfort requirements, humidity, equipment duty, and consultant specifications. Confirm the required filter class and whether cooling, heating, or dehumidification is part of the makeup-air scope before selecting the unit.
What should I send for fresh air fan selection?
Send required supply CFM, exhaust CFM if makeup air, opening size, static pressure if available, voltage, quantity, project city, and filter or control requirements.
Is a fresh air fan the same as an exhaust fan?
No. A fresh air fan supplies outdoor air into the building, while an exhaust fan removes indoor air out of the building. Many projects need both systems balanced together.
Do kitchens need makeup air with roof exhaust fans?
Many commercial kitchens need makeup air because roof exhaust fans and hood systems remove large airflow. Without replacement air, the kitchen can become negatively pressurized and hood performance may suffer.
Can fresh air fans include filters?
Filter sections may be reviewed depending on the product, air quality requirement, installation location, and project specification.
