Product context
About Grace Series
Grace Series is designed for large factories, warehouses and high-heat industrial spaces. Its controlled air movement helps equalize temperatures and reduce stagnant air in large occupied spaces.
7,500 airflowFresh-air evaporative coolingIndustrial spaces
Operating principle
How it works
Draw in hot air
The fan or blower pulls hot outdoor air through the wet pads.
Deliver cooled air
Heat is absorbed through evaporation before filtered air reaches the occupied space.
Built for industrial use
Engineering features
High-volume fresh air
Continuous outdoor air movement helps reduce heat in open or semi-open facilities.
Efficient cooling pads
Even wetting supports stable evaporation, filtration and cooling performance.
Durable construction
Corrosion-resistant housing and reinforced components support long service life.
Simple controls
Timer, temperature and optional humidity controls make daily operation easier.

Before specifying
Operating notes
Cooling performance depends on entering air temperature, relative humidity and ventilation. The system performs best where cooled fresh air can move continuously through the space.
Service routine
Maintenance checklist
Before seasonal shutdownTurn off the water supply, empty and clean the tank, and dry the cooling pads.
During extended storageDrain circulating water and check the tank, pads and housing for scale, algae or corrosion.

Airflow and Installation Details
Review the airflow pattern, control system, installation conditions and operating range for this fan.
Model and drive configuration
Grace Series is represented by RTF-YF-4EEX in the 2026 export configuration. The source specifies RTFANS PMSM direct drive and 5 PCS blades. The technical table lists the supplied model values, including diameter, airflow, power, voltage, current, speed, noise and weight.
Application range and installation
The source labels maximum application range in cubic meters (m³). This is a volume entry, not a floor-area rating in square meters. Select fan quantity and placement using mounting height, building dimensions, obstructions and the occupied zones. These fans circulate room air; outdoor-air ventilation and process extraction require a separate design.
Performance and service
Review the selected model's operating conditions and noise measurement method before quotation. Have a qualified installer check structural support, blade clearance, safety retainers and electrical supply. Isolate power before inspection and follow the supplied motor and controller manuals for maintenance.
