System thinking

Matching the right equipment<br>to real on-site conditions.

Commercial kitchens need oil fume collection, exhaust, purification, make-up air and cooling; factory projects need exhaust, ventilation and cooling organized around fume, heat, odor, workstation layout and air paths. Xin Changfeng provides equipment selection and technical support based on actual parameters.

  • Confirm space, pollution sources and improvement goals
  • Check airflow, pressure and installation conditions
  • Select the equipment and confirm interfaces

Core solutions

Core Kitchen & Factory Solutions

Solution design and equipment selection for the main air environment problems of kitchens and factories.

01 / RESTAURANT EXHAUST

Kitchen Exhaust & Purification

Organize the air path around fume collection, duct transport, fan exhaust and purification, configured by kitchen size and site conditions.

Fume CollectionDuct TransportFan ExhaustPurification
  • DT Cabinet Centrifugal Fansselected by exhaust volume and duct resistance
  • Centrifugal Fansfor ducted air delivery and exhaust
  • Purification Equipmentconfirmed by airflow and service space
02 / RESTAURANT AIRFLOW

Kitchen Ventilation, Make-Up Air & Cooling

For high temperature, stuffiness and exhaust-induced negative pressure, improve air organization with exhaust paths plus make-up air and cooling.

  • Evaporative Air Coolersfor make-up air and cooling where evaporative cooling fits
  • Multi-Wing Centrifugal Fansfor low-to-medium pressure supply/exhaust
  • KTJ Silent Fresh Air Cabinetsfor low-noise air supply
03 / FACTORY VENTILATION

Factory Exhaust & Process Ventilation

Build supply/exhaust paths from fume, heat, odor and process exhaust needs, checking media, system resistance and duty.

  • Centrifugal Fansfor exhaust and process air with duct resistance
  • DT Cabinet Centrifugal Fansfor centralized cabinet supply/exhaust
  • Multi-Wing Centrifugal Fansfor low-to-medium pressure air delivery and OEM
04 / FACTORY COOLING

Factory Ventilation & Heat Relief

For equipment heat, stagnant air and hot workstations, improve circulation with mechanical exhaust, evaporative cooling and roof natural ventilation.

  • Negative Pressure Fansfor high-volume exhaust and whole-space air change
  • Evaporative Air Coolersfor fresh air and cooling where suitable
  • Roof Turbo Ventilatorsfor roof heat extraction via natural wind and buoyancy

Equipment matching

Bigger is not better — matching the duty is what works.

Engineering calculator

Ventilation & Exhaust Engineering Calculator

For quick pre-design estimates of airflow and make-up air. Final selection still requires checking duct resistance, elbows, purifiers, noise and installation.

Recommended Exhaust Airflowm³/h
Recommended Make-Up Air (85%)
Make-Up Air Units

Q = L × H × V × 3600 × margin; make-up air ≈ 80%–90% of exhaust.

Theoretical Airflowm³/h
Duct Cross-Section
Recommended Total Pressure

Q = area × velocity × 3600; ~15% margin included in total pressure.

Recommended Total Exhaustm³/h
Estimated Fan Units
Recommended Inlet Area

Q = volume × air changes; inlet area ≈ 2.5 m/s inlet velocity.

Professional Note

This tool provides preliminary estimates and does not replace design drawings. Kitchen projects require checking cookline type, diversity factor, hood style, duct length and purifier resistance; factory projects require checking heat sources, openings, prevailing wind and workstation needs.
