FAQ
Questions you may have before purchasing.
Xin Changfeng mainly produces cabinet centrifugal fans, water-cooled fresh air units, commercial kitchen air conditioners, axial fans, backward-curved fans, KTJ silent fresh air cabinets, multi-wing centrifugal fans, industrial centrifugal fans, evaporative air coolers and negative pressure fans, serving restaurant kitchens, school and corporate canteens, hotel kitchens, factory workshops, warehouses and commercial buildings.
Cabinet centrifugal fans suit kitchen exhaust, school and corporate canteens, hotel back kitchens, commercial building supply/exhaust and factory workshop ventilation. Selection should account for airflow, static pressure, duct length, elbow count and installation position.
Yes. Water-cooled fresh air units mainly supply fresh air, relieve back-kitchen negative pressure and provide spot cooling, suiting restaurant kitchens, school and corporate canteens, factory workshops and hot workstations by drawing in outdoor air and cooling it evaporatively.
Commercial kitchen air conditioning suits hotel kitchens, restaurant back kitchens, school and corporate canteens, central kitchens and other hot work areas. For kitchens with heavy exhaust, balance exhaust and make-up air first, then configure the air conditioning.
The exhaust system continuously removes kitchen air; without steady make-up air the kitchen becomes negatively pressurized, making doors hard to open, reducing exhaust efficiency and drawing cool air from the dining area. Balanced make-up air keeps exhaust and intake in equilibrium and improves the back-kitchen environment.
Axial fans generally suit high-flow, low-pressure ventilation; centrifugal fans better handle supply/exhaust systems that must overcome duct resistance. Choose by airflow, static pressure, duct length and scenario rather than just by size or power.
Negative pressure fans mainly provide whole-space ventilation and remove hot air; evaporative air coolers deliver cooled fresh air to work areas; water-cooled fresh air units combine make-up air with spot cooling. Large plants often combine negative-pressure exhaust with air-cooler or fresh-air supply, sized by space volume, heat sources and workstation layout.
At least provide the application, space dimensions, target airflow, static pressure, duct length, elbow count, installation position, air media, noise limits and operating hours. Without full parameters, provide a floor plan or duct layout and let the manufacturer assist with initial selection.
