Optional Negative-
Pressure Systems

A negative-pressure system puts the fan where it can draw the heat and fumes from the kiln and bring them to the exit point. Negative pressure is often specified as a safeguard against a tear in the hose. Any  pre-engineered system can be modified easily for a negative-pressure application.

Vent a Kiln System shown here with the STANDARD Positive Pressure System on an octagonal ceramic digital kiln.

Standard Positive-
Pressure Systems

The pre-engineered electric kiln venting systems are available as  "positive pressure" systems. A positive-pressure system simply means that the fan is attached to the hood and pushes the heat and fumes to the exit point.

     Free Standing, Portable, Modular, Expandable Vent-A-Fume/Vent-A-Kiln  Corp. Safety Screens to help provide a "piece of mind" while firing a kiln, or to help keep unauthorized personnel out of a restricted work area.
     The outer surface of a kiln during firing can exceed 400 F (204 C),  which can cause severe injury if accidentally touched. To alert  students, children and others to be careful when near a kiln, each panel on Safety Screens for kilns is imprinted in bright safety yellow: CAUTION - KILN IN OPERATION.
     Easy to assemble, Safety Screens are made with flame-retardant canvas secured to 1/2-in. round steel tubing that is galvanized for corrosion resistance. Standard units feature three and four 2-ft. wide by 3-ft.  high panels. Single panels can be purchased to expand upon standard units.

     Designed to program your Vent-A-Kiln ventilation system to turn on at  the start of your firing process and turn off after all excess heat and  fumes are eliminated from the work area. It is ideal for electric kilns, electric ovens and small electric furnaces.
     Automatic start-up of ventilation prior to kiln firing is a safety  measure to eliminate the potential hazard of forgetting to turn the  system on. Automatic shutdown ensures that all fumes have been  eliminated from the area and contributes to energy efficient operation.
     Programmable Mini-Time Controllers also can be used with Vent-A-Fume  systems for process emissions, or used to operate other equipment that  does not exceed the maximum load specifications below.
