Explosion vent panels can come in many different shapes, types and vacuum resistance depending on application.
Square, rectangular, round, flat or domed.

The VIGILEX VL is suitable for all applications with low vacuum or working pressure (up to 50 %
of static burst pressure) such as elevators, conveyors, silos, cyclones.
With an integral flange ready to install, covering the breaking point, the VIGILEX VL ensures
a strong mechanical durability. The attached wide gasket provides the VIGILEX VL a perfect
dustproof seal.
The standard burst pressure is 0,1 bar (max. 0,5 bar) at 22º C (72º F).

The VIGILEX VL-R is a curved explosion vent panel shaped according to a customer specification need.
VIGILEX VL-R is suitable for all applications with low vacuum or working pressure (up to 50 %
of static burst pressure) such as elevators, conveyors, silos, cyclones.
With an integral flange ready to install, covering the breaking point, the VIGILEX VL-R ensures
a strong mechanical durability. The attached wide gasket provides the VIGILEX VL-R a perfect
dustproof seal. The standard burst pressure is 0.1 bar (max. 0.5 bar) at 22 °C (72 °F).
The VIGILEX VL-R is tested after it has been formed, to ensure that the correct burst pressure
is observed.

The VIGILEX VL-S is a low cost model suitable for all applications with low vacuum or working
pressure (up to 50 % of static burst pressure) such as elevators, conveyors, silos, cyclones.
It is provided without flange and with a gasket covering the breaking points.
The standard burst pressure is 0.1 bar (max. 0.5 bar) at 22 °C (72 °F).

The new VIGILEX VL-SANITARY is designed especially for hygienic applications in food or pharmaceutical
industry. Dedicated to protect systems with low vacuum or working pressure (up to 50 %
of static burst pressure) such as spray dryers.
The high technology designed of this panel avoids contaminations.
The standard burst pressure is 0.1 bar (max. 0.5 bar) at 22 °C (72 °F).

The VIGILEX VD is a domed panel, designed to protect plants with a vacuum and pulsating
processes. The domed design is optimal for pneumatic operated vessels like filters and
cyclones with strong vibration.
With an integral flange ready to install and gasket included, the VIGILEX VD meet all your
safety issues with the most demand in your application. The attached wide gasket provides
the VIGILEX VD a perfect dustproof. The standard burst pressure is 0.1 bar (max. 0.5 bar) at
22 °C (72 °F).

The VIGILEX VD-HV is a strong domed panel, designed for use in applications where the
operating pressure approaches the burst pressure, or where high vacuum pressure may exist.
In the need for applications where the explosion vent is exposed to pulsating duty such as
reverse jet cleaning systems on dust collectors with high vacuum.
With a large flange and gasket included, the one layer domed panel VIGILEX VD-HV meets
all your safety issue to protect equipment and facilities. The standard burst pressure is 0.1 bar
(max. 0.5 bar) at 22 °C (72 °F).

The V-DEX diverter is used to deflect explosions propagating through the ducts, preventing the
spread of flames or overpressures in connected vessels.
This device reduces the risk of flame spread.
