  • Product description

    Scroll centrifugal duct fan 140 mm | 12V DC | 50 W | 370 m³/h | IP55 | 0–10V / PWM control | ES-DAN-72

    140 mm centrifugal scroll fan with a 12 V DC motor. Delivers up to 370 m³/h, and the speed is controlled smoothly by a 0–10 V or PWM signal – directly from a humidity, temperature or CO₂ controller.

    Key point:
    Low-voltage supply makes it suitable where 230 V is not available or not wanted: vehicles, off-grid solar systems, boats, telecom cabinets. IP55 protection for dusty and humid environments.

    We will help you set up speed and automatic control

    We will advise how to adjust this fan's speed and how to switch or control it automatically according to room conditions – humidity, temperature or CO₂ concentration. We will select a suitable speed controller, thermostat, humidity or CO₂ sensor and explain how to connect them.

    Contact us: tel. +370 658 01033 or e-mail info@elsprendimai.eu

    In your e-mail, briefly describe the situation: room purpose and size, fan model and what you want to control – speed, humidity, temperature or CO₂.

    Wholesale quantities: special prices for larger orders. State the required quantity in your e-mail and we will send you an individual offer.

    Operating principle

    The radial impeller draws air through the axial inlet and the scroll housing directs it to the outlet, generating higher pressure than axial fans, so air can be pushed through ducts and filters.

    The brushless DC motor (about 1750 rpm, 3.5 A) is controlled by a 0–10 V or PWM signal: output is varied smoothly from minimum to maximum without extra controllers.

    Why choose this fan?
    Smooth speed control, low energy use and safe low voltage – ideal for automated systems and off-grid power.

    Technical specifications

    Product type Scroll centrifugal DC fan 140 mm
    Code ES-DAN-72
    Power supply 12 V DC
    Power 50 W
    Current 3.5 A
    Speed 1750 rpm
    Airflow 370 m³/h
    Control 0–10 V or PWM
    Protection IP55
    Motor Brushless DC (BLDC)

    Main functions

    • Smooth control – 0–10 V or PWM signal – straight from the controller.
    • Low voltage – 12 V DC – safe and suitable for off-grid sources.
    • Airflow – Up to 370 m³/h through ducts and filters.
    • IP55 protection – Resistant to dust and water jets.

    Where is it used?

    • Off-grid solar and battery systems
    • Vehicles, campers, boats
    • Telecom and control cabinets
    • Greenhouses and dryers with automatic control
    • Ventilation driven by humidity, temperature or CO₂ sensors

    Use by need

    For automation.
    0–10 V / PWM input connects directly to a PLC or controller.
    For off-grid systems.
    Powered directly from a 12 V battery or power supply.
    For installers.
    Compact scroll housing for ducts.

    Practical application

    Choose a power supply with at least 3.5 A current reserve. Connect the control signal to a humidity, temperature or CO₂ controller so the fan runs only as much as needed.

    Pros

    • 0–10 V / PWM control
    • 12 V DC supply
    • Up to 370 m³/h
    • IP55 protection

    Cons / limitations

    • Requires a 12 V DC power supply
    • Stated airflow is at zero duct resistance
    • Not for explosive atmospheres

    Safety and installation notes

    • Connection must be made by a qualified specialist
    • Fit overload protection in the supply circuit
    • Mount the fan on a solid base
    • Disconnect power before maintenance
    • Keep inlet and outlet unobstructed

    Suitable when you need:
    • ventilate a room in an off-grid system
    • control ventilation by humidity, temperature or CO₂
    • cool cabinets or equipment
    Check before use:
    • the power supply is 12 V and at least 3.5 A
    • the controller has a 0–10 V or PWM output
    • the 140 mm connection fits
    Important reminder: A fan works best when its airflow and pressure match the system resistance.

    FAQ

    How is the speed controlled?
    With a 0–10 V or PWM signal from a controller, thermostat or humidity / CO₂ regulator.
    Can it be connected to 230 V?
    Only via a 12 V DC power supply.
    What is the difference between 12, 24 and 48 V versions?
    Supply voltage, power and airflow – choose by available supply and required output.
    Is it suitable for humid environments?
    Yes, IP55 protects against dust and water jets.
