Blauberg Valeo 75/100

Extract ventilation systems installed in high-rise buildings and premises.For buildings with mono-pipe ventilation system.For mounting in kitchens and bathrooms.Installation in casing for flush or surface mounting.

The Valeo ventilation unit is designed for installation in a plastic or fireproof casing.The front panel is made of snow-white UV-resistant plastic.Filter with filter class G4 for motor, impeller and ductwork system protection against soiling.The filter is easily accessible for service operations.The ventilation unit with motor is fixed inside the casing with special latches.Due to modern design and various colour modifications the front panel matches well with any interior.

TIMER (VALEO...Т)
Depending on wiring connection the fan is off or runs permanently at low speed. The fan is turned to higher speed with external switch 50 s after activation. After turning the switch off the fan continues operating within 6 min at higher speed and then reverts to default operation mode.ADJUSTIBLE TIMER (VALEO...ТR)
Depending on wiring connection the fan is off or runs permanently at low speed. If the fan is turned on with an external switch it switches to higher speed 0 to 150 s after switch activation. After turning the fan off it continues running at higher speed within 2 to 30 minutes and then reverts to previous mode. The fan run-out time and delay time for higher speed are regulated with the internal regulator.INTERVAL SWITCH (VALEO...I)
Depending on wiring connection the fan is off or runs permanently at low speed. In interval mode regulated from 0,5 to 15 hours the fan switches periodically to higher speed for 10 minutes. The switch interval is adjusted with the internal regulator. If light in the room is turned on the fan switches to higher speed in 50 s. After light is off the fan reverts to interval mode operation.HUMIDITY SENSOR (VALEO...H)
Depending on wiring connection the fan is off or runs permanently at low speed. The fan switches to higher speed as relative humidity in the room increases from 60 % up to 90 % and switches off as humidity drops by 10 % below set level. If light in the room is turned on the fan switches to higher speed in 50 s. The run-out time is set by the internal regulator from 2 to 30 minutes.

Two-speed motor with a centrifugal impeller. Minimum energy demand.The impeller has forward curved blades.Automatic maintaining of constant air flow depending on variable air resistance of the duct.Balanced impeller ensures low noise operation.Best aerodynamic characteristics due to a special scroll casing design.Ball bearings provide long service life.

Step speed control with an external speed controller, e.g. a CDP-3/5 model which is available upon order.Wide range of system controls with programmable parameters (timer, adjustible timer, internal switch, humidity sensor).

BP 80: plastic casing for flush mounting.

Made of quality ABS plastic and equipped with a gravity backdraft damper.

Gravity backdraft damper

Installed in a wall or ceiling during general construction works by mounting brackets supplied as a standard.The casing is equipped with oblong slotted joints to facilitate mounting.Connection to main ventilation shaft with flexible air ducts.Exhaust spigot diameter 80 mm.After installation works cover the unit with a protecting cover to prevent dirt ingress.After finishing works install the Valeo unit inside the casing.For exhaust ventilation of neighbour rooms additional spigots may be connected to the casing.

BF 80: fireproof casing for flush mounting.

Made of silicate plates based on calcium silicate and has high thermal insulating properties.Equipped with a fire-retarding damper to prevent fire and smoke expanding along air ducts. If temperature in the duct reaches 90°C the thermal fuse closes the damper.When the fan is off, the fire-retarding damper serves as a backdraft damper.

Fire-retarding damper

The fan casing is installed in a wall or ceiling during general construction works by mounting brackets supplied as a standard.Connection to the main ventilation shaft with flexible air ducts. Exhaust spigot diameter 80 mm.Power is supplied to the fan through a sealed electric lead-in on the casing.After installation works cover the unit with a protecting cover to prevent dirt ingress.After finishing works install the ventilation unit inside the casing and connect it to wiring system.For exhaust ventilation of neighbour rooms extra spigots may be connected to the casing on the left (BFL modification), on the right (BFR modification), on the bottom (BFD modification).
