    BESF box ventilator


    Design

     
    BESF konstruktion

    BESF box ventilators are made from Aluzinc® AZ185 class C4 in accordance with EN/ISO12944-2 and insulated for sound and condensation with 30 mm mineral wool.

    As standard, BESF can handle gas temperatures up to 60°C.

    When used as a smoke extract fan:
    BESF146-180 can as standard cope with up to 200°C for 60 min.
    As standard, BESF200-280 can handle up to 300°C for 60 min.



    Fan impeller

     
    BESF ventilatorhjul

    The ventilator impeller is an F-impeller made from galvanised steel.

    It has forward-curved blades, which means that the box ventilator is able to generate a high pressure for its compact size.



    Spigots

     
    BESF gummiliste The spigots on BESF have rubber gaskets to ease mounting of ducts.


    Oscillation dampers

     
    BESB svingningsdæmpere

    To minimise noise and vibration, the box ventilator is fitted as standard with efficient oscillation dampers mounted on brackets.



    OGSR transition piece

     
    BESF med OGSR To minimise system pressure drop when connecting to a duct system, we recommend the use of an OGSR transition piece (accessory).

    OGSR is a specially developed circular transition piece with integral guide panels; it can be supplied for BESF200, 225, 250 and 280 and allows maximum capacity and efficiency to be achieved.

    OGSR is not available with other BESF models.

  3. Motor types Add to print

    BESF box ventilator

    BESF box ventilators have their motor connected directly to the ventilator impeller.

    BESF box ventilators are available with three types of motor:

    - EC motor
    - single-phase motor
    - 3-phase motor

    The motors are made to protection class IP54 and all materials are as a minimum class F (155 °C). All motor types have integral current overload protection.


    EC motor

    The EC motor for BESF is a permanent-magnet motor of class IE3 with motor control for 1 x 230 V or 3 x 400 V connection. The motor control and the motor are protected from overloading, blocking, over and under voltage, and over heating.

    The motor control is factory programmed by EXHAUSTO for optimal operation of the ventilator. It only requires mains connection and a control signal from an EXHAUSTO EFC1P or MAC12 controller or a 0-10V signal.

    The motor controls also provide a Modbus interface for fan control and alarm read-offs etc.


    Single-phase and 3-phase motor:

    Single-phase motors can be selected for BESF146/BESF160/BESF250. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO controllers EFC15, EFC35 and MAC12 (with MPR4 or MPR8 module).

    3-phase motors can be selected for BESF250/BESF280. The motor is designed for a fixed rpm of 1400 or for frequency control (max. 50 Hz) by external frequency converter. The 3-phase motors must use external motor protection, or can be controlled by an external frequency converter (with integral motor protection) to max. 50 Hz.

  4. Installation Add to print

    BESF box ventilator

    The box ventilator can be mounted in various positions. Note, however, that the ventilator must not be positioned with the motor turned downwards.

    Standard installation: A

    Alternative installation options B/C/D:

    BESB monteringsmuligheder

     

    During installation, consideration must be given to opening the door for servicing and for access to door screws (see dimensions table on pages 7 and 15 in the product instructions where opening radius R is given). There should also be enough space to insulate the ducts.

    In installation options B and D, with the door facing upwards, special fittings must be used to hold the door (accessory).

    The box ventilator should not be screwed onto the supporting base. The base must be stable and vibration free, with no sagging.

  5. Flue gas resistance Add to print

    BESF

    As standard, BESF can handle gas temperatures up to 60°C.

    When used as a smoke extract fan:
    BESF146-180 can as standard handle up to 200°C for 60 min.
    As standard, BESF200-280 can handle up to 300°C for 60 min.

  6. Accessories Add to print

    BESF box ventilator


    FLF Flexible connector

     
    FLF Flexforbindelse FLF flexible connector is made from reinforced glass fabric with integral clamps.

    FLF is fitted directly onto EXHAUSTO box ventilators as a coupling to the ventilator ducts and minimises any possibility of vibrations moving along the duct system.


    BFL Brandflex

     
    BFL Brandflex BFL is made from steel-reinforced glass fabric, ceramic material and silica fibre.
     
    BFL Brandflex satisfies the fire safety requirements for building components of materials class A2-s1,d0 in accordance with EN13501-1.


    THA/THAV Roof terminal

     
    THA THAV afkasttaghætter 150 x 100 Roof terminals THA and THAV are designed for air exhausts from EXHAUSTO box ventilators BESB and BESF.

    THA is insulated for condensation and has a horizontal exhaust, while THAV is insulated for both sound and condensation and has a vertical exhaust.
