Air filtration, ventilation, hydronic equipment, heat exchange and HVAC controls for commercial, industrial and infrastructure projects.
From individual components to coordinated system packages, YONGFAN helps engineers, contractors and system integrators select equipment around real operating conditions.
Selection support for airflow, pressure, temperature and control logic.
From airside components to hydronic equipment and controls, each family can be specified on its own or coordinated as a complete project package — selected around the real duty of your system.
Pre-filters, medium-efficiency filters, HEPA/ULPA media, activated carbon filters, FFUs and cleanroom terminal equipment — engineered for low resistance across the full service life.
Axial, mixed-flow, centrifugal, roof, tunnel, smoke-exhaust and explosion-proof fan series.
Ventilation, purification, duct centrifugal, fire smoke-exhaust and explosion-proof cabinet units.
Fire and smoke dampers, volume control dampers, VAV terminals, plenums and acoustic components.
Molecular filtration for control rooms, server rooms and contaminated industrial exhaust streams.
Plate, tubular and storage exchangers, packaged skid units and direct-mixing heating equipment.
Pressurization, expansion, water make-up, VFD supply sets, manifolds and condensate recovery.
Physical treatment and auxiliary equipment for scale control and sustained heat-transfer performance.
Thermostats, sensors, actuators, motorized valves, balancing valves and general HVAC valves.
Send airflow, pressure, temperature, filtration grade or target contaminants — our engineers will map them to the right product family and configuration.
Engineering, manufacturing, documentation and export coordination within one project workflow.
YONGFAN supplies HVAC system accessories and control solutions for commercial and industrial applications.
Our range covers fans, air distribution, filtration, valves, sensors, actuators, controllers and supporting equipment for offices, hospitals, data centers, factories, cleanrooms and infrastructure projects.
Duty-based sizing from real project parameters.
Materials, motors, grades and control modes.
Controlled assembly, balancing and inspection.
Documentation, export packing and dispatch.
Airflow, pressure loss, temperature, humidity, cleanliness, water quality, target gases and installation conditions all influence equipment selection. YONGFAN helps match components around the actual duty of the system.

Water Side
Pressurization, water make-up, distribution, heat exchange and water-treatment equipment for closed HVAC water loops.
View solutionIndustrial air carries more than dust. Petrochemical plants, refineries, wastewater facilities, steel plants and some data-center environments contain H₂S, SO₂, Cl₂, NOx, NH₃ and VOCs at the molecular level — where conventional particulate filters cannot reach.
DUTY 01
Fresh-air and recirculation filtration for control rooms, server rooms and sensitive electronic equipment.

DUTY 02
Treatment of contaminated industrial exhaust before discharge — a separate duty from occupied-space protection.
View exhaust-treatment systemsEach facility brings a different combination of air quality, temperature, vibration, safety and uptime requirements. Select an industry to see how the system package changes with the duty.
01 / 08
Molecular contaminants can rapidly corrode DCS boards and sensitive controls. The airside package combines gas-phase filtration, hazardous-area ventilation and corrosion-resistant components.
02 / 08
Critical lithography and process zones need stable laminar flow, low outgassing and targeted removal of acid, base and organic molecular contaminants.
03 / 08
Clean spaces require verified terminal filtration, stable pressure relationships and materials compatible with routine disinfection and decontamination.
04 / 08
Low pressure loss, dependable heat transfer and controllable water-side distribution help protect uptime while supporting energy-performance targets.
05 / 08
Daily traffic ventilation and emergency fire scenarios demand robust fans, reversible thrust and components selected for verified high-temperature duty.
06 / 08
Operating rooms, ICUs and isolation wards need distinct airflow directions, dependable terminal filtration and quiet equipment operation.
07 / 08
Complex occupied zones benefit from demand-based air distribution, balanced hydronics and low-noise components that maintain comfort without excess energy use.
08 / 08
Production environments need durable air movement, heat recovery and plant-room equipment sized around dust loading, thermal duty and long operating hours.
Nominal catalogue ratings rarely reflect actual pressure loss, contaminant load, temperature or installation geometry. YONGFAN configures the equipment package around the project duty, then supports verification, documentation and delivery.
Selection · Manufacturing · Verification
Fans, filters and hydronic equipment are selected against actual airflow, static pressure, fluid conditions and system resistance—not model number alone.
Dimensions, casing materials, filtration grades, motors, controls and connection details can be coordinated around the installation environment.
Applicable assemblies are checked against their rated operating conditions, with balancing, leakage or functional inspection completed before release.
Material preparation, fabrication, assembly and inspection follow defined checkpoints so critical build details remain traceable through production.
Selection data, technical schedules, interface drawings, wiring information and available BIM resources support review and installation.
Protective packing, shipping documentation and multilingual technical communication are coordinated around international project delivery.
Lower resistance, replaceable media and maintainable assemblies can reduce operating demand and unnecessary component waste.
Sustainability starts with efficient system performance, maintainable construction and longer useful equipment life.
Low-resistance filtration and correctly matched ventilation equipment help limit unnecessary continuous fan demand.
Washable nylon and metal-mesh filters provide reusable primary-filtration options where the application permits.
