DESIGN

Fan Impeller

The ventilator impeller is a B-impeller made from cast aluminium.

It has backward curved blades, thus ensuring low energy consumption and the further advantage that less dirt is attracted, with impaired impeller efficiency as a result.

Spigots

The spigots on BESB have rubber gaskets, with a transition piece on the extract side specially developed for minimum pressure drop.

OSCILLATION DAMPERS

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

SPLIT HINGES

The BESB box ventilator has split hinges, which enable the door to be removed for installation and servicing, even in very confined conditions or for transport to difficult locations.

CONDENSATION OUTLET

The BESB box ventilator is designed to transport air with an air humidity of less than 80% RH.

BESB is available as a special model with a condensation outlet for air with over 80% RH.

Split Version

If there are problems moving the BESB box ventilator in one piece, it may be ordered in a SPLIT version.

– The box ventilator must be assembled by an EXHAUSTO-approved fitter
– The box ventilator must receive final testing before handover by the fitter.

ENERGY

BESB box ventilator

The BESB box ventilator is a low-energy ventilator, in which ventilator housing, centrifugal impeller and motor all work together as one technology.

All BESB box ventilators fulfil the future requirements for 2015 laid down in the Ecodesign Directive EC327/2011.

BESB is listed by the Danish electrical power utility companies as an ‘energy-saving fan’® – that is a highly energy-efficient ventilator.

MOTOR TYPES

BESB box ventilator

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

BESB 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 BESB is a permanent-magnet motor of class IE5 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 BESB250. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO controllers EFC16, EFC35 and MAC12 (with MPR4 or MPR8 module).

3-phase motors can be selected for BESB500. 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 they can be controlled by an external frequency converter (with integral motor protection) to max. 50 Hz.

Design

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

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

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

 

 

Oscillation Dampers

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

OGSR TRANSITION PIECE

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.

Motor Types

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 IE5 (BESF25041EC: IE4) 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 EFC16, 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.

Design

DTH is made from cast aluminium, giving it a high corrosion resistance. It is painted in black RAL 7021, a suitable colour for most roofs.

Horizontal Exhaust

DTH is an extract fan with a horizontal exhaust.

The design ensures an optimum air handling solution with minimum noise.

Fan Impeller

DTH roof fan is ideal for ventilation tasks requiring efficient and economical ventilation.

The specially developed centrifugal impeller with backward curved blades ensures high efficiency and low operating costs.

Service

DTH roof fan is easy to open for cleaning and maintenance.

Motor Types

DTH roof fan

DTH is available with 2 motor types:

  • Single-phase voltage controlled motor
  • EC motor

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


EC motor

The EC motor is a highly efficient permanent-magnet motor of class IE5 with motor control for a 1 x 230 V connection. The motor control has been specially developed for compatibility with the EXHAUSTO DTV roof fan and, when used with this motor, ensures the lowest possible operating costs.

The motor control protects the motor from overloading, blocking, over and under voltage, and over heating. It is factory programmed by EXHAUSTO for optimal operation of the fan. It only has to be connected to a 1 X 230 VAC supply and to an EXHAUSTO EFC1P or MAC12 controller.

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


Single-phase motor

Single-phase motors can be selected for the 2 smallest DTH models. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO EFC16, EFC35 and MAC12 controllers (with MPR4/MPR8 module).

DESIGN

Fan Impeller

The ventilator impeller is a B-impeller made from cast aluminium.

It has backward curved blades, thus ensuring low energy consumption and the further advantage that less dirt is attracted, with impaired impeller efficiency as a result.

Spigots

The spigots on BESB have rubber gaskets, with a transition piece on the extract side specially developed for minimum pressure drop.

OSCILLATION DAMPERS

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

SPLIT HINGES

The BESB box ventilator has split hinges, which enable the door to be removed for installation and servicing, even in very confined conditions or for transport to difficult locations.

CONDENSATION OUTLET

The BESB box ventilator is designed to transport air with an air humidity of less than 80% RH.

BESB is available as a special model with a condensation outlet for air with over 80% RH.

Split Version

If there are problems moving the BESB box ventilator in one piece, it may be ordered in a SPLIT version.

– The box ventilator must be assembled by an EXHAUSTO-approved fitter
– The box ventilator must receive final testing before handover by the fitter.

ENERGY

BESB box ventilator

The BESB box ventilator is a low-energy ventilator, in which ventilator housing, centrifugal impeller and motor all work together as one technology.

All BESB box ventilators fulfil the future requirements for 2015 laid down in the Ecodesign Directive EC327/2011.

BESB is listed by the Danish electrical power utility companies as an ‘energy-saving fan’® – that is a highly energy-efficient ventilator.

MOTOR TYPES

BESB box ventilator

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

BESB 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 BESB is a permanent-magnet motor of class IE5 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 BESB250. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO controllers EFC16, EFC35 and MAC12 (with MPR4 or MPR8 module).

3-phase motors can be selected for BESB500. 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 they can be controlled by an external frequency converter (with integral motor protection) to max. 50 Hz.

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

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

 

 

Oscillation Dampers

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

OGSR TRANSITION PIECE

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.

Motor Types

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 IE5 (BESF25041EC: IE4) 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 EFC16, 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.

VVR200-4-1 130 860
VVR250-4-1EC 250 1,900
VVR315-4-1EC 470 3,360

Design

VVR is made from cast aluminium, giving it a high corrosion resistance. It is painted in black RAL7021.

 

Vertical Exhaust

VVR is an extract fan with a vertical exhaust.

The design ensures an optimum air handling solution with minimum noise.

Fan Impeller

VVR wall fan is ideal for ventilation tasks requiring efficient and economical ventilation.

The specially developed centrifugal impeller with backward curved blades ensures high efficiency and low operating costs.

Service

VVR roof fan is easy to open for cleaning and maintenance.

Guide Panel

If there is a high level of humidity in the extract air, the VVR wall fan can be ordered with a guide panel.

The guide panel ensures that moisture does not run down the wall but is guided away from it.

Motor Types

VVR wall fan

VVR is available with 2 motor types:

  • Single-phase voltage controlled motor
  • EC motor

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


EC motor

The EC motor is a highly efficient permanent-magnet motor of class IE5 with motor control for a 1 x 230 V connection. The motor control has been specially developed for compatibility with the EXHAUSTO DTV roof fan and, when used with this motor, ensures the lowest possible operating costs.

The motor control protects the motor from overloading, blocking, over and under voltage, and over heating. It is factory programmed by EXHAUSTO for optimal operation of the fan. It only has to be connected to a 1 X 230 VAC supply and to an EXHAUSTO EFC1P or MAC12 controller.

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


Single-phase motor

Single-phase motors can be selected for VVR160/VVR200. All motors are 4-pole with 1400 rpm, and permit direct voltage control using EXHAUSTO EFC16, EFC35 and MAC12 controllers (with MPR4/MPR8 module).
