Ratings and sizes
We make unrated, 2PSI and 5PSI rated devices, and every rated product is certified by qualified engineers. Your ventilation engineer sets the rating for each opening.
Standard sizes are listed where we have them, such as the 5PSI airlock at 3.0 x 1.4 x 2.2m high. Everything else is built to your opening.
