Air was blown through a floor duct into the base of the computer, rising through it, and exhausting through a ceiling duct, returning through an exhaust-blower air filter and cooling coils to the floor duct again.
Control of solder fume is generally achieved using local exhaust hoods, simple blowers with a filter or low-volume high-velocity (LVHV) ventilation systems.
They will ride exercise bikes in clean air and in a room with the air polluted by the exhaust of leaf blowers and lawnmowers.
"Exhaust pollution per leaf blower per hour is the equivalent of the amount of smog from 17 cars driven one hour and is localized in the area of blower usage," the grand jury said.
Sam Leonard, an emissions expert at General Motors, said his company was considering another approach: attaching an air blower to the exhaust system.
Push pull systems use both blower fan/tubing and exhaust fan/tubing systems, which can combine the effects of both single systems to lower the DPM levels in the dead-end face area.
A turbocharger employs a gas turbine operated by the exhaust gases to drive a centrifugal blower.
The auxiliary ventilation systems considered include: blower fan and tubing; exhaust fan and tubing, jet fan, and push pull system.
There are also options for airbrushing, extra vents added to the nose, chromed engines, built-in beer holders and blowers, which push the exhaust out for noisier impact.
A typical SOFC system consists of an SOFC stack and a blower, a heat exchanger, an exhaust-burner as the primary components in its balance of the plant.
A high-compression blower was placed so that it would exhaust foul air through one of the two open doorways.
