    Galvanised steel housing, IP44 protection, class F insulation and S1 continuous duty – for commercial and industrial supply and extract systems.
    Airflow
    7000 m³/h
    Power / voltage
    830 W / 380 V
    Speed
    1364 rpm
    Protection
    IP44

    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 from the duct and discharges it to the opposite rectangular connection – air moves in a straight line, and the radial design overcomes the resistance of filters, heaters and long ducts.

    The motor runs at about 1364 rpm. The three-phase motor speed is best controlled with a frequency inverter – by demand, humidity, temperature or CO₂.

    Why choose this fan?
    High airflow in a rectangular duct without extra transitions and simple speed control.

    Main functions

    • Airflow – Up to 7000 m³/h.
    • Direct installation – Connects directly into a rectangular duct.
    • Continuous duty – S1 duty, class F insulation.
    • Speed control – By demand, humidity, temperature or CO₂.

    Where is it used?

    • Commercial ventilation systems
    • Offices, shops, sports halls
    • Production halls and warehouses
    • Kitchen extraction (with grease filters)
    • Air handling units with filters and heaters

    Use by need

    For designers.
    Standard rectangular duct sizes and clear data.
    For installers.
    Installed directly in the duct run.
    For businesses.
    Reliable continuous operation.

    Practical application

    The stated 7000 m³/h is achieved at zero resistance. Use flexible connectors to the ducts so vibration is not transmitted.

    Pros

    • Up to 7000 m³/h
    • Rectangular connection 800×500×900 mm
    • IP44, S1 duty
    • Adjustable speed

    Cons / limitations

    • Airflow drops as system resistance increases
    • Not for explosive atmospheres
    • Not certified for fire smoke extraction

    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

    Quick selection guide

    Suitable when you need:
    • ventilate commercial or production premises
    • build a supply or extract system with rectangular ducts
    • control ventilation by humidity, temperature or CO₂
    Check before use:
    • the 380 V supply fits
    • the duct size matches 800×500×900 mm
    • the capacity suits your system
    Important reminder: A fan works best when its airflow and pressure match the system resistance.

    FAQ

    How is the speed controlled?
    The three-phase motor speed is best controlled with a frequency inverter – by demand, humidity, temperature or CO₂.
    Is it suitable for kitchen extraction?
    Yes, with grease filters; air temperature up to +50 °C.
    Is it suitable for fire smoke extraction?
    No, it is not certified for that.
