The wind tunnel is quite expensive equipment and technically complex. Some people are not able to buy a wind tunnel, looking at the prices of a new attraction. For this purpose we have in stock pre-owned wind tunnels. After some time with the proper construction of marketing the buyer will be able to switch over to more expensive equipment, earning money on this business, starting with a small one. Pre-owned wind tunnel is the same wind tunnel which simply has some operating time. All wind tunnels that we are keeping in stock are fully serviced, technically intact and ready for operation.
