VERTICAL FLAMELESS VENTING

NZ DUCT+FLEX  are the only company in NZ who can offer this safety feature.

Only dust extraction filter units with VFV ensure, in the unlikely event of a dust explosion, the explosion pressure will vent safely up into the sky with NO FLAME emerging.

What makes filters with VFV so safe?

The world's Safest filter!

Should a filter catch fire and an explosion occur, dust extraction filters with Vertical Flamess Venting vent vertically: through the roof, via an ATEX approved explosion membrane.

Vertical Release protects the area around the dust filter unit - there is no requirement to mark off exclusion areas as required with a SIDE venting explosion panels - possibley saving you large areas of your car park or at least not limiting where the filter unit can be sited.

There is no FIRE BALL: all the dust and flames are contained within the filter unit! Due to the  strengthened design, the unit itself will remain intact, apart from the ATEX safety explosion release panel in the top.

Our filters from Denmark with this VFV technology are unique in the New Zealand, and in fact in the entire global dust extraction market.

These units have been independently tested and certified by the German FSA test house.

Ask to see the Certification or Video confirmation from an authorised test house, if you are offered a product that makes the same claims. We can provide these. 

The entire filter assembly is designed to pass this test - retrofitting explosion membranes to a basic filter assembly which has not been proven to withstand an event is dangerous. The result of airborne panels and thousands of screws will be devastating to anyone in it's path should an explosion occur.

ATEX and IECEx compliant units supplied as required. 

SIDE Venting explosion relief requires an exclusion zone to be marked, to be compliant.

ATEX certified explosion relief panels are top ventig with VFV - no exclusion zone necessary
