In a closed workshop or garage can be poisoned by fumes from smoke when working with welding or grinder. For it removal from the premises we need powerful ventilation. It can be assembled from the pipes and the duct fan.
- duct fan 100 mm;
- sewer pipe 110 mm;
- mounting clamps for pipes;
- elbow 90 degrees;
- twisted pair wire;
- rocker switch.
The Assembly process ventilation
In the wall near the ceiling making the hole for the pipe diameter. It starts a short sewer pipe and the outside connects with the knee. The knee joins the vertical pipe and is closed by the visor from rain. The higher it get, the better it will come out the air with smoke in a natural way without turning on the fan.
Pipes are fastened to the walls and ceiling with clamps.
Inside the short pipe is inserted into duct fan 100 mm. Can be used and 125 mm, but then need an adapter.
The fan in the pipe secured with a rubber gasket or screws. It is powered through the key switch.
To the pipe with a fan joins a long pipe. It is necessary to bring to the workplace. It drills a large drill in several rows. The edge is closed by a plug.
When you turn on the fan air intake will be implemented uniformly throughout the length of the pipe through the holes. This solution is more compact and cheaper than the installation of exhaust hood, in the workshop which usually interferes with normal work.
