What's the flow ragulator for vacuum? My system is Particle source -> filter -> valve -> vacuum pump. The flow rate is about 1 acfm. While the particulate is captured by filter, the pressure drop is increased. To maintain the flow rate, the valve should be opened gradually. Is there a type of...

I am looking for a regulator for vacuum sampling system. I'm collecting the particles on the filter and the pressure drop keep increase then I have to adjust (open) the valve for vacuum pump. Is there a sort of regulator to keep the flow through the filter? I guess the vacuum regulator or flow...

In Addition to, The valve should being opened when the pressure is getting increased.

I'm looking for a flow regulator for the vacuum pump. I'm sampling the particules from the combustion source with filter and vacuum pump. However, the pressure drop is getting increased so, I have to monitor and adjust the valve for vacuum pump. Is there any regulator for the vacuum pump then...

The health effect of diesel particle is not really and exactly figured out yet, since its composition and interaction in the body is very complicated. But, many of toxicologiest and engineers working on this and they believe it can cause the mortality. Generally, the diesel engines exhaust a...

I am looking for a ceramic flow straightener for the drop tube furnace. I thought to use the sintered metal, the tube could be broken since the thermal expansion is different with alumina tube. Where can I buy some porous ceramic plate? The themperature in my application would be about 900...
