Function:
The blower sucks the dry but polluted ambient air (R.H. < 95%) via the air intake (1)
the chamber (2). The air is cleaned with the prefilter at the upstream side of the blower
The retained particles cause an increase in the differential pressure. To maintain the
function of the system and to protect the blower (4) a vacuum relieve valve (3) is in-
stalled.
The blower (4) “compresses” the air at about 1.5 psi. The compressed air is
fed into the sterile chamber (5). The sterile filter retains microorganisms and all kind
bacteria and/or other contaminants.
To protect the blower there is also a pressure relief valve which opens if the sterile filter
is blocked. At the outlet (11) the sterile air is fed to the tank or an other point of use.
During sterilization of the sterile chamber and the sterile filter elements, the disc
valve (7) needs to be closed to prevent steam entering the blower. To maintain a good
steam quality the steam filter (8) is standard on the P-SLF box. After sterilization the
condensate can be drained out the discharge valve (9 + 10).
* Standard:
110 V/230 V , 60 Hz
(P-SLF 0288-0 to 1152-0)
460 V , 60 Hz
(P-SLF 1536-0 to 3072-0)
Also other voltage or frequencies available
on request.
Note:
All P-SLF boxes are also available in 60 psi
version. This means it can be sterilized
with saturated steam up to 60 psi or a
steam temperature of 290°F.
The name of such a box would e.g. be
P-SLF 0576-4.
