To ease installation an MGO wall duct can be used with the VVR wall fan. The MGO is made from galvanised sheeting with 25 mm insulation against sound and condensation. An integral anti-backdraught shutter is included and the duct can be adjusted to lengths from 210 - 400 mm, to match the thickness of the wall. MGO can be mounted together with diffusor (1), inlet sleeve ILMF and cover flange MGAF as shown below. INSTALLATION SOLUTION 1 If a MGO terminates flush with the internal wall, a covering flange (MGAF) and inlet sleeve (ILMF ) must be fitted before the diffusor is fitted (1). INSTALLATION SOLUTION 2 If the (MGO) is shorter than the wall's thickness, an inlet (ILU) and sleeve (MF) or a spiro tube (SR) must be fitted before the diffusor (1) is fitted. INSTALLATION SOLUTION 3 If there is a long distance between the MGO and the exhaust location, an ILU inlet connected to SR spiral tube must be mounted.

VVR is made from cast aluminium, giving it a high corrosion resistance (corrosion class C4 in accordance with EN ISO 12944-2). It is painted in black RAL7021.

VVR is an extract fan with a vertical exhaust.
The design ensures an optimum air handling solution with minimum noise.

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.

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.

To ease installation an MGO wall duct can be used with the VVR wall fan.
The MGO is made from galvanised sheeting with 25 mm insulation against sound and condensation. An integral anti-backdraught shutter is included and the vent can be adjusted to lengths from 210 - 400 mm, to match the thickness of the wall. The MGO can be mounted together with a diffusor (1) inlet sleeve ILMF and cover flange MGAF as shown below.
If a wall duct (MGO) terminates flush with the internal wall, a covering flange (MGAF) and inlet sleeve (ILMF ) must be fitted before the diffusor is fitted (1).
Mounting solution 2
If the MGO is shorter than the thickness of the wall, an inlet (ILU) and sleeve (MF) or spiral pipe (SR) must be installed, to which the diffuser (1) is attached.
If there is a long distance between the MGO wall duct and the exhaust location, an ILU inlet connected to SR spiral tube must be mounted.
