DC7025 70x70x25mm DC Cooling Fan
A 25mm-deep 70mm fan balancing airflow, pressure and 12V/24V/48V compatibility for industrial and communication equipment.
DC7025 adds a 25mm frame depth to the 70mm format, raising the available airflow and pressure compared with slim 70mm designs. Its three speed levels reach 44.87CFM and 9.11mmH2O, while 12V, 24V and 48V versions support a wide range of equipment power systems.

Airflow and Pressure from a 70x70x25mm Fan
A 25mm frame gives this 70mm platform more cooling margin while preserving three voltage families.
Balanced Output in a 70mm Frame
Up to 44.87CFM and 9.11mmH2O provides useful airflow with moderate pressure for compact equipment.
25mm Depth for Added Cooling Margin
The deeper frame offers more performance headroom than 10mm-thick 70mm fans when the enclosure allows the extra depth.
12V to 48V Coverage
A single mechanical size can be evaluated across conventional 12V electronics, 24V controls and 48V communication systems.
Selectable Speed and Noise
3,000, 4,000 and 5,000RPM variants allow acoustic and thermal requirements to be matched more precisely.
70mm Multi-Voltage DC Cooling Fan Overview
DC7025 occupies the middle ground between slim 70mm cooling and larger 80mm formats. Its 25mm depth provides additional pressure without changing the 70mm mounting footprint.
Glass-fiber-reinforced PBT impeller and housing are rated UL 94V-0. Available functions include FG, RD, PWM, Auto Restart and Polarity Protection; final wiring, connector, signal definition and bearing choice should be confirmed for the project.
DC7025 P-Q Curves for 3,000 to 5,000RPM
The 3,000, 4,000 and 5,000RPM curves show the airflow margin available within the same 70mm footprint. Use the expected grille, heat-sink and duct losses to identify the operating point before selecting voltage and speed.
Industrial and Communication Uses for a 70mm Fan
The 70mm format suits equipment that needs more output than a slim fan but cannot move to an 80mm footprint.

Industrial Control Units
DC7025 fits controllers and automation modules that need more cooling than a slim fan but cannot accept an 80mm footprint.
Communication Equipment
The 48V family can be assessed for communication terminals and network power assemblies with a 70mm opening.
Power Conversion Modules
Moderate static pressure supports airflow across heat sinks and densely arranged power components.
Compact Storage Systems
Storage and embedded computing enclosures can use the 25mm depth where drive bays and boards create moderate resistance.
Equipment with Short Air Guides
Short guide ducts can direct the available airflow toward a hot zone when the final operating point is validated.

70x70x25mm DC Cooling Fan FAQs
A: DC7025 uses a 70x70x25mm frame. Confirm mounting-hole spacing and clearance with the product drawing before installation.
A: Published options include 12V / 24V / 48V. Select the exact model according to rated voltage, current and controller compatibility.
A: The published range reaches 44.87CFM and 9.11mmH2O. Use the P-Q curve for the actual operating point.
A: FG, RD and PWM are listed as function options. Signal voltage, frequency, wiring and minimum duty must be confirmed before connection.
A: The product range lists cycleseal or ball bearing. Confirm the bearing code, operating temperature and expected service conditions with the selected model.
A: Project-specific voltage, speed, wire length, connector and control functions can be discussed. Performance must remain tied to an approved model and sample validation.
