In modern industrial environments, heat dissipation and dust prevention for control cabinets and electrical cabinets are crucial to ensuring long-term stable operation. An excellent exhaust fan must not only efficiently cool but also effectively block the intrusion of dust and particles, extending equipment lifespan. This article introduces the ingeniously designed and high-performance REF series filter fan, offering comprehensive and reliable protection for your cabinets.
Selecting the appropriate exhaust fan is key to ensuring effective cabinet heat dissipation. The following four steps will guide you through the selection process:
Step 1: Calculate the Required Heat Dissipation Airflow
Airflow calculation is the foundation of selection. Use the following simplified formula for an initial estimate:
Required Airflow (m³/h) = [Total Heat Generation in Cabinet (W) × 0.05] / (Permissible Temperature Rise °C)
Total Heat Generation: Estimate the sum of heat generated by all components (e.g., PLCs, drives, power supplies) in the cabinet.
Permissible Temperature Rise: Refers to the maximum difference between the internal temperature of the cabinet and the ambient temperature. It is generally recommended to keep this within 10°C.
Example: If the total heat generation is 500W and the temperature rise requirement is ≤10°C, the required airflow ≈ (500 × 0.05) / 10 = 2.5 m³/h.
Note: This formula is a simplified calculation. Actual requirements may involve more factors, but it serves as a preliminary reference. The selected fan's "airflow with filter cotton" should exceed the calculated value.
Step 2: Confirm Installation Dimensions and Method
Cutout Dimensions: Check the size of the installation cutout reserved on the cabinet panel for the fan.
Cabinet Thickness: Ensure the cabinet panel thickness falls within the 1.5–3.5mm range to accommodate the REF series' adjustable buckle.
Installation Method: The REF series features a buckle-style installation, requiring no screws, and offers strong compatibility. Confirm compatibility with your cabinet structure before installation.
Step 3: Evaluate Environmental and Protection Requirements
Dust Protection Needs: In dusty environments, filtration is essential. The REF series comes standard with G3 medium-efficiency filter cotton, providing effective dust protection. Its tool-free quick-release design allows for easy replacement.
Protection Rating: The IP32 rating prevents the intrusion of solid objects and dripping water, making it suitable for most industrial indoor environments. For humid or splash-prone environments, consider products with IP55 or higher protection ratings.
Step 4: Compare Models and Performance
Model Selection: Choose a model based on airflow requirements. For example, for 400 m³/h, select the REF700 (410 m³/h with filter cotton); for 800 m³/h, choose the REF1400.
Noise Considerations: If the equipment is noise-sensitive, pay attention to the noise value (dBA) and prioritize models with lower noise levels while meeting airflow requirements.
Voltage Confirmation: Based on the site's power supply conditions, select the standard 230V or customize options from 115V to 400V.
Summary:
When selecting an REF series filter fan, first match the heat dissipation requirements based on the "airflow with filter cotton," then confirm the installation dimensions and voltage. Its unique buckle installation and quick-release filter cotton design significantly reduce installation and maintenance costs, making it an ideal choice for industrial cabinet heat dissipation.
Simplified Installation, Saving Time and Effort
Features an innovative buckle-style design that allows direct snap-on installation without screws, greatly reducing installation time. Ideal for batch installation scenarios.
Wide Compatibility, Flexible Adaptation
The adjustable buckle design supports cabinet thicknesses from 1.5–3.5mm, solving selection challenges caused by varying cabinet specifications.
Effective Protection, Clean Interior
Equipped with an IP32 protection rating, effectively preventing the intrusion of solid objects and dripping water. Standard G3 filter cotton efficiently filters dust and particles, ensuring a clean cabinet interior.
Easy Maintenance, Low Cost
Filter cotton replacement requires no tools; simply open the top knob for quick operation, significantly reducing long-term maintenance costs.
Global Voltage, Customizable on Demand
Standard configuration supports 230V AC voltage, with customization options from 115V to 400V, meeting power requirements in different regions worldwide.
The REF series offers two models to meet different heat dissipation needs:
| Parameter Item | REF700.230 Model | REF1400.230 Model |
|---|---|---|
| Rated Voltage/Frequency | 230V AC 50/60Hz | 230V AC 50/60Hz |
| Free Airflow | 550/600 m³/h | 1150/1350 m³/h |
| Airflow with Filter Cotton | 380/410 m³/h | 750/950 m³/h |
| Rated Current | 0.30/0.35 A | 0.55/0.65 A |
| Power | 55/65 W | 110/150 W |
| Noise Level | 62/65 dBA | 68/71 dBA |
| Operating Temperature Range | -20°C ~ 80°C | -20°C ~ 80°C |
Model Interpretation:
REF700: Free airflow of approximately 700 m³/h (actual 550/600 m³/h).
REF1400: Free airflow of approximately 1400 m³/h (actual 1150/1350 m³/h).
230: Standard rated voltage of 230V.
