Ventilation Control Devices [VCD’s]
We manufacture a range of Airlocks designed to suit your specific needs and to suit every style of overcast we supply, ranging from unrated lightweight styles through to 5PSI rated Airlocks.
5PSI Rated Airlock
We have designed our rated Airlocks to be fully manufactured in our workshop, which means that they can be transported underground and bolted into position without any assembly necessary. This design also includes a floor which makes for an easier transition. Standard size is 3.0 x 1.4 x 2.2 metres high.
