General attention should be paid to the installation of ventilation ducts during the construction of all-steel experimental benches
all-steel experimental bench cannot completely eliminate harmful gases, but it can at least reduce their overflow, so you must install it in the laboratory and take protective measures yourself.
2. Those that cannot be connected by a single pipe, but are limited to the same room on the same floor, can be connected in parallel.
3. The fan should be installed at the end of the pipe as much as possible.
4. The shorter the pipe length, the better.
5. The fewer experimental benches connected to a fan, the better. The exhaust channel should be as upright as possible, and the higher the channel, the better.
6. If the wind speed of the air duct needs to be changed, the corresponding frequency conversion adjustment system should be configured.
7. The end of the exhaust duct should be kept away from the air supply port of the air supply duct to prevent the harmful gases from being sent to the all-steel experimental bench through the exhaust duct.
