Call a duct cleaning company, they can get it.
You need a filter retainer
Reverse the fan? Otherwise, need to know the what and where of the filter that was "sucked up."
Air is pulled into the crankcase from the PCV (positive crankcase valve) the fresh air enters through this filter to keep dirt from being sucked into the crankcase. This filter is usually located inside the air filter housing.
You could get sucked up by a black hole if you were close enough to feel its gravitational pull more strongly than another force to counterbalance it which would otherwise prevent you from getting sucked inside, such as, for example the orbital inertia which prevents the stars in our galaxy, including the Sun, from getting sucked into the Milky Way's central supermassive black hole.
The filter might have been too strong for the gold fish to swim awa from, so it got sucked in
It is probably dirty if it is a portable window air. If it is a central a/c, then there are multible answers. The "a" coil could be dirty. The air filter is dirty. You recently had your blower motor replaced and it is running backwards. Your filter got sucked into the blower wheel. Your a/c has a small leak in it and is low on freon. Someone kinked the lineset and it won't let enough freon through. The furnace fan is not working.
You. Or your remainders, to be more precise.
it shouldn't hurt it any. the filter on the oil pickup will keep it from being sucked into the engine.
None. Those engines draw so much air a filter would be sucked into the engine.
In the intake. You can spray it directly on the air filter and it will be sucked into the intake.
It is a machine that you place about 150 feet away from any planned outdoor activities. It attaches to a propane tank and burns it to produce carbon dioxide. It has a collection filter on it where as the mosquito are attracted to this scent, theyre sucked up in a bag where they die. It works.
When you ran out, you probably sucked up a bunch of water and dirt into the fuel filter. Have you local garage mechanic pull the tank, change the filter and clean the inside of the tank. I'll bet there's a bunch of crap still in there and this is a good opportunity to get it out.
