HaB Direct logo


Designed for the analysis of expired gases, HaB have created a Douglas Cart System that is as compact as possible, yet functional and high quality. All HaB Douglas Bag Cart Systems offer a return loop as standard so that sampled air can be returned to the bag. As they are made to order, we can also try to incorporate any specific requests that you may require.

Please contact us for details of bespoke options, including different sized Douglas Bags (from 5 to 1000 ltrs).

Please note that the colour of the board on the cart is now a pale grey.
