But what is now become my only aware of last week and is well noticed here anyone disturbing, is the oval shape of the intake manifold. This is not round as with other manufacturers, but precisely oval. Thus, no universal accessory can be used, or only with difficulty.
My planer has a connection for a vacuum cleaner, which is of course round and not oval. And experts know how much dirt when planing a door flying through the area. That's not even with suckers not very nice and no more so.
The oval port haunts me now everywhere. I have to be able to suck well as a kind of flexible mini-hose to behind radiators and other bottlenecks. Yes, this also has a round connector.
There should probably be an adapter, but why must be oval and not round the tube?
In physics, a complete round passage offers (tunnel / tube / pipe / hose) the air less of a target and there are also less turbulence than an oval. Thus, the vacuum cleaner in theory could perhaps even a tad better suck or quieter. So why then oval? In order to sell adapters can?
