Inquiry (采购产品): Air blower (hydrogen safe) We want to take a grab sample (not a calibrated sample) of a potentially radioactively contaminated hydrogen atmosphere from a 400 cubic foot tank through a sampling head with porous filter paper and then exhaust the gas (mix of hydrogen and nitrogen) back into the 400 c.f. tank. We do not want any make-up air added as we do not want the tank to be pressurized by this activity. We need about 50 to 60 liters per minute flow. **** Hidden Message ***** John Miller 89128 Company: Lawrence Liv. Natl Lab E-mail: miller29@llnl.gov **** Hidden Message ***** miller29@llnl.gov
