air tight rrom
i need a 6-12 m3 air tight area for some testing. it can be a room or a large sturdy 'bag'. it must be very cheap.
any ideas?
eng-tips forums is member supported.
1) does this area just need to be air tight, or will there be a pressure differential? we will have a positive pressure differential
2) what kind of access do you need between the inside and outside of this structure? (i.e. will you need to run any wires / hoses between the inside and outside of the structure?)we will need to be able to enter the area to initially set up the equipment and yes there will be several wires/hoses between the inside and outside
3) does this structure need to have a transparent observation window? not essential
