loading

Top hinged vent can be

re set after explosion

Ordering and Calibration:

When ordering please state finished overall width and height in millimetres.

State the minimum required opening/release pressure. This will be factory set. Note – it may be

necessary when stating this to consider local climatic conditions to allow for wind and other salient

external effects which may exceed the release pressure and cause the vent to open when not required.

The release pressure can also be checked, calibrated and adjusted for higher or lower values even after

installation.

Under normal operating conditions the vent can be closed after having been released and will be ready

to operate again upon closure. It should be checked for correct operation however to ensure the blast

pressure that the unit has vented has not been greater than anticipated and in consequence could have

damaged or misaligned the vent unit.

The system is designed to accept opaque, clear, transparent, translucent and also louvered ventilation panels

The Blast and Explosion Vents and Blast and Explosion

Louvers are designed primarily to release overpressure from

within a building or internal area. They are often required

however to allow airflow at other times especially in the

case of plant and machinery. The Blast and Explosion

Louvres when fitted with the Blast Louver panel will do just

that until such time as the pressure needs to be released.

Pressure that is not aspirated through the Blast Louver will

operate the release mechanism and the Blast and Explosion

Louvre will release the panel and allow it to open.

The Blast and Explosion Vents and Louvers are also available

with various types of solid insulated and also clear glazed

panels. Allowing light transfer or not as the case may be. The

frame system of both the Blast and Explosion Vent and Blast

and Explosion Louver is thermally broken and is

complimented with the use of thermally broken infill panels.

A wide range of powder coat colour finishes is also available.

Products are factory finished and packaged ready for

dispatch.

The Blast and Explosion Vents can also be upgraded to

provide ballistic protection. This helps protect against

fragmentation which can be produced in commercial

environments. As one example these Blast and Explosion

Vents have been used to protect workers in areas such as

the laboratory testing of high speed revolving parts or

pressure pipework systems.

Installation and Maintenance:

The unit is factory pre-assembled and after offering the frame into the prepared structural opening it is

secured using proprietary frame or machine screw fixings

The system can be sealed around its perimeter for weather tightness using proprietary sealants

The system is lightweight and can sometimes remove the need to use other expensive handling

equipment during installation

After installation the unit can also be checked for operating release pressures and adjusted if necessary

to accommodate increased or decreased blast/explosion threats from within the building

Unless the previous blast/explosion has been particularly onerous for the unit it will simply close and is

ready for operation – no need to replace the unit. Check that the unit has correctly re latched and is not

damaged

The unit is already factory calibrated ready for installation

Installation is simple and reduces site cost

The unit is lightweight and is often installed using one person

The unit requires little maintenance. Check for correct operation, clean and check release pressure if

required

The centre panel of the unit is also available in clear finish to allow daylight transmission if required
