Installation example Cross talk attenuator ETS (shown inserted in ducting with valve) ∆ p Pa fa 50321T* ETS 100 ETS 125 Function Advantages
T* = Trickle ventilation 3 /h The ABLUVENT is a grille with
an electrically operated
shutter
to control the air flow. The unit includes a filter. It is ideally operated via the light switch.
The louvres open when the
room is in use (light is switched
on). A trickle ventilation is given
when the room is not used, as a minimum air flow will be extracted when the shutter is
closed. ABLUVENT ABV 100 Delayed operation on closure of5 minutes. Cross talk attenuator ETS Advantages Optimises the economic efficiency of central ventilation
systems. Ventilation systems for
toilets and
bathrooms withoutwindows must operate 24 hours.If traditional valves are installed,
the full air flow is extracted e.g.
for 18 hours and half the air flow
for 6 hours at night no matterof how often the room is used.This means a lot of energy is
lost. Using of ABLUVENT can, depending on the building, bring
energy savings of up to30%. Surprisingly simple and cost effective solution to reduce noise transmission in central
ventilation systems. Installation
direct into ducting behind the
valve. Optimal solution to avoid noisetransmission by duct system. Stepless adjustment of air flowvolume. Attenuation figure The attenuation figure can be
doubled if you have two facingrooms which both have an ETSattenuator in the ducting. Excellent attenuation figures(see diagram). Noiseless operation. Incorporating (changeable) filterto keep duct system clean. Simple installation by pressinginto ducting (behind valve). Material Air flow volume Polyurethane foam with improved reaction in case of fire, fulfills DIN 4102, class B1, UL-94-HF 1, MVSS 302 and others. Virtually no additional resistanceto the system. The opening pitch of the louvres
can be set stepless between 15and 80 degrees (covered, insidefacia). The diagram above
shows the air flow in relation to
the setting (under pressure). Technical data Connection Minimizing system cost by usingsimpler ducting. The unit can be operated using
a standard on/off switch, ideally
combined with the light switch.Supply: 220/240 V / 1 ph., power: 5 W. Double insulated,
radio suppressed, protection to IP 44.
Casing made from white polymer.
The thermal shutter works withshort delay (approx. 30 secondsto open and 5 minutes to close). Can be used with any brand ofvalve. ETS 100 Ref. No. 4521 Nominal duct 100 mm ETS 125 Ref. No. 4522 Nominal duct 125 mm
