QUALITY VENTING
The EnviroVent 2 is a Downdraft Ventilation System designed to extract fumes from your electric kiln and vent
them outdoors before they have a chance to enter the room. Because it is a DownDraft Ventilation System the
EnviroVent 2 also improves the fi ring atmosphere in the kiln while it is protecting you from the odorous fumes
that can be emitted from certain clay bodies and glazes when they are fired.
Here's How It Works
A
designated number of holes are drilled in the lid and floor of the kiln
either in the factory or on location. A spring loaded plenum cup (see
diagram) is placed under the kiln and tensioned between the floor of
the kiln and the floor under the kiln. The holes in the floor of the
kiln are drilled in a tight pattern so the plenum cup can cover them
all. The other end of the cup is connected by 3" ducting to a fan which
is generally mounted on the wall. On the opposite end of the fan the
air is ducted through the wall to the outside air. The plenum cup has
3 additional holes from which it draws room temperature air to mix with
the heated air from the kiln. This serves 2 purposes. Since the kiln
air is mixed with cooler room air the air coming out of the end of the
vent is never hotter than an average hair dryer. Secondly, the holes in
the plenum cup are sized to reduce the vacuum on the kiln chamber so
only a small amount of air is moving through the kiln. This ensures the
firing time is not affected and the ware is not at risk.
