LanChang 4100 air volume water-cooled fresh air machine

The Lanchang 4100 water-cooled fresh air machine is a 4100 air volume integrated water-cooled fresh air equipment specially designed by Lanchang for the kitchens of small and medium-sized restaurants, fast food restaurants, and snack bars. It integrates four major functions: outdoor fresh air introduction, water cooling, fume filtration, and indoor air makeup, addressing industry pain points such as stuffiness, fume accumulation, and poor ventilation in catering kitchens. It is also the preferred model for cost-effective ventilation and cooling among local catering businesses in Shenzhen. As a standardized water-cooled fresh air machine for small and medium-sized commercial use, the 4100 is rated for a kitchen area of 30-60㎡, with a single unit covering 4-6 cooking stations. It combines refrigeration, ventilation, and air purification, suitable for various commercial scenarios such as local street food restaurants, private kitchens, and tea shops.

1. Core advantages of water-cooled constant temperature fresh air system
   LanChang 4100 water-cooled fresh air fan is equipped with a full copper water-cooled heat exchanger core. The water circulation system quickly cools outdoor high-temperature fresh air in summer and preheats incoming air in winter, achieving a 60% improvement in cooling efficiency compared to ordinary axial fans. It saves 30% of electricity during long-term operation and avoids the problems of direct blowing from traditional air conditioners, stuffy kitchens, and high energy consumption. The device is equipped with a multi-layer composite oil-proof filter screen that can intercept PM2.5, oil fume particles, dust, and odor. The magnetic filter screen is easy to disassemble and clean, reducing maintenance costs for stores. The centrifugal silent fan stably outputs 4100m³/h of fresh air and runs with low noise, without disturbing the kitchen’s food preparation. The entire machine has a stainless steel anti-corrosion shell and a nano oil-proof coating to resist long-term oil fume erosion. It supports 24-hour uninterrupted operation and is suitable for catering businesses that operate all day long.
   II. Intelligent Control and Local Installation Services
   The Lanchang 4100 water-cooled fresh air fan is equipped with a simple smart control panel, allowing for one-click adjustment of air volume and water cooling level. It can be paired with directional air supply outlets, ensuring cold air directly reaches the chef’s workstation without interfering with open-flame cooking appliances. Customers who purchase the Lanchang 4100 water-cooled fresh air fan at local stores in Shenzhen can enjoy integrated services including on-site inspection, free installation, and comprehensive product warranty. With quick and convenient after-sales maintenance nearby, there’s no need to wait for cross-regional repairs. It has become a popular model for ventilation renovations in the Pearl River Delta’s catering kitchens.
   Unlike mere exhaust fans or household fresh air machines, the Lanchang 4100 water-cooled fresh air machine integrates ventilation, cooling, and purification into a single unit. Its compact size doesn’t take up space in the kitchen, and its flexible installation makes it suitable for both new store openings and ventilation renovations in existing stores. If you’re looking for a small water-cooled fresh air machine with a wind volume of around 4000 in Shenzhen, the Lanchang 4100 stands out as an optimal solution for ventilation and cooling in small and medium-sized restaurant kitchens, thanks to its stable performance and comprehensive local after-sales service.
