Skutt EnviroVent 2: Kiln Vent Option

SKUTT KILNS EnviroVent 2 Ventilation System

Downdraft Ventilation System

See PRODUCT VIDEOS tab for installation instruction video

• The Skutt EnviroVent 2 requires a 120 Volt outlet.
• The fan motor moves 140 cfm of air out of the room. Make sure you consult with an HVAC professional to be sure the room is provided with adequate make-up air.
• The EnviroVent® 2 comes with 8 ft. of 3 in. diameter, heavy duty, flexible aluminum ducting to go from the plenum cup to the vent motor. If more is needed to vent to the outside, you may order additional ducting from Skutt. Do not use thin-walled dryer ducting.
• The fan motor comes equipped with a 3 in. exhaust tube designed to pass through most walls and roofs. The maximum exiting temperature when installed correctly is 160 ºF.
• If a vent is ordered with a kiln, the holes in the lid and slab are often drilled in the factory. If there are no holes drilled, consult the EnviroVent® 2 manual and drill the holes according to the recommendations for your model.
• If you are venting a kiln between 12 cu/ft and 24 cu/ft you will need to use a Dual Intake Kit to draw air from 2 areas of the kiln. This kit may also be used to vent 2 kilns under 12 cu/ft.

VENT 2 KILNS With 1 MOTOR
Now you can vent 2 kilns with a single vent with the Skutt EnviroVent 2. The new 140 CFM Motor allows you to vent 2 kilns up to 12 Cubic Feet each, or one kiln between 12 and 24 Cubic Feet, with one Envirovent 2 Motor.

WALL MOUNTED MEANS NO HEAT AND NO VIBRATION
The new design of the kiln ventilation system is wall mounted. This moves the vent motor away from under the kiln so the motor is no longer exposed to the heat and can no longer transfer any vibration into the kiln.

SPRING LOADED PLENUM CUP RETAINS SEAL THROUGHOUT FIRING
As your kiln heats up the brick expands. When it expands the hot face of the kiln floor, the inside, expands more than the cold face or underside. This causes the slab to cup, or become slightly concave on the bottom. The result is that the center of the kiln floor moves upward at higher temperatures. The spring loaded cup follows the floor ensuring at tight seal throughout the firing process.

NEGATIVE PRESSURE MEANS NO LEAKING
Since the Skutt EnviroVent 2 is wall mounted it pulls the air through the duct work instead of pushing it. This means if you were to ever form a leak in your duct work the fumes would not be pushed into the room.

ABILITY TO CONTROL WITH KILNMASTER OR GLASS MASTER CONTROLLER
Now with the purchase of the new Skutt EnviroLink you can control exactly when the Envirovent 2 turns on and off during a firing on a GlassMaster or KilnMaster kiln.

SAME QUALITY VENTING
The Skutt 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 firing 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.

Better Heat Uniformity
Most people are aware of the fact that heat rises. The Skutt EnviroVent 2 helps compensate for this rising heat by creating a flow of air moving back down the kiln chamber. As the air moves in a downward direction it is also deflected by ware and shelves causing turbulence. This turbulence helps move heat to cooler areas of the kiln like the center.

Better Kiln Atmosphere
When you are firing in an electric kiln you are firing in an Oxidation atmosphere. The EnviroVent 2 helps bring in more oxygen and flush out fumes which can form a reduction atmosphere. A reduction atmosphere can be desirable in a gas or wood fired kiln however it only causes problems in an electric kiln. Your elements will last longer, your glazes will be clearer and brighter and you will help prevent glazes migrating between pieces.

Better Working Environment
Prior to the introduction of kiln ventilation systems it was still necessary to vent the kiln. This was done by propping the lid open with a wedge of brick until the kiln reached 1000°F (538 °C). Not only was this inconvenient, it also radiated the fumes right into the room.

A Better Vent
A new benefit of the EnviroVent 2 is that it is now a Negative Pressure System. This means that since the motor is pulling the air instead of pushing the air, if there is ever a hole in the ducting the fumes will not escape into the room. Also since the motor is now mounted away

The Skutt EnviroLink
The EnviroLink is an electrical switching device that can be controlled by an automatic kiln to determine when a vent turns on and off.

Certified safe.
The Envirovent 2 is the only vent UL and c-UL listed to be used with Skutt Kilns.
