Question
Will tobacco nicotine and tar
12
affect the Lossnay Core?
Are there any places where
13 the Lossnay cannot be
used?
What are the soundproofing
14 properties for music rooms
and karaoke bars?
What is the short circulation
15 of the air intake/exhaust air
outlet?
Is total operation possible
16
with switches?
Tobacco smoke tends to stick to dust in the air, and when it passes
through the Lossnay Core, most of the nicotine and tar will be filtered by
the air filter.
However, in very smoky places (ex. pachinko parlour), or when used for a
long period, the tobacco odor will accumulate and move to the intake
side. In this case, the Core and filter should be replaced.
The Lossnay cannot be used where toxic gases and corrosive Core's
such as acids, alkalis, organic solvents, oil mist or paints exist.
The Lossnay cannot be used to recover the heat of air containing odors.

When an LGH-50R
was installed in a karaoke bar and the noise was
measured, the following results were obtained. When the noise in the
room was 96.5 dB (A), the noise level at a point 30 cm from the
intake/exhaust grille on the outside wall was 67.5 dB (A). This shows a
soundproofing effect of 29.0 dB (A).
The soundproofing effect when the noise level is 100 dB (A) is
approximately 30 dB (A).
The Lossnay uses the forced simultaneous supply/exhaust method so the
insufficient ventilation found in standard ventilators with no air intake is
not found.
Caution
(1) The fresh air supplied to the room should not short circulate being
drawn back into the return grille. It should flow through the entire
room.
(2) The relation of the supply and suction flows of the air conditioner must
be also considered.

The air intake/exhaust grille on the outer wall is in the open and so
there is a natural wind, with the result that short circulation will not
occur easily. However, if the wind blows from the exhaust grille
towards the intake grille, short circulation may occur, so these should
be placed as far apart as possible.
The guideline for the distance is three times the duct diameter.
