The vacuum pump system generates a vacuum that can be con-
trolled either through the hand terminal (see chapter 5.3, page 15)
or a PC.
Collection flask (Fig. 2/
12
) collects on the suction side of the pump
particles and drops that were, contrary to the requirements of the
pump, suctioned from the vacuum chamber. The collection flask is
coated (implosion protection) and fastened to the vacuum pump
system via a flask clip.
The high-performance condenser at the pump outlet once again
recollects solvents from the pumped gas instead of allowing it exit
into the environment or fume hood. The high-performance con-
denser is surrounded by a shell for temperature insulation and
explosion protection.
Solvents deposited in the high-performance condenser are col-
lected in the coated (for explosion protection) collection flask (Fig.
2/
15
). A flask clip secures the glass flask to the condenser flange.
A recirculating cooler or continuously flowing cold water cools the
high-performance condenser to the condensation temperature.
