Operation and Maintenance Manual
Manual 118 Issue 15 Page 8 of 28
3.6 External Filter
Warning! Never operate a SA suction unit without a MGE filter capsule.
The filter capsules are a sealed disposable bacterial or hydrophobic filter capsule. Both the bacterial
and hydrophobic filters have bacterial retention of 99.9999% ensuring safety and hygiene for patient
and operator. The 0.3 micron particle retention of the filter medium also gives not less than 99.985%
Dispersed Oil Particulate (D.O.P.) and so provides an effective barrier against possible aerosol
contamination. The hydrophobic filter also has an integrated micro porous membrane on the rear of
the filter medium which allows a clear flow of air through one way and an excellent block against any
accidental back flow the other. The external filters are fitted between the vacuum connector and the
filter capsule mount, and can be either a bacterial or hydrophobic filter. The connector, mount, and ‘O’
rings are autoclavable. However, the filter capsules are ‘Single Patient Use’ and must not be
autoclaved. The external filter must be changed with every patient and renewed in accordance with
the recommendations detailed in the ‘Daily Procedures’.
Warning! The filter capsules are single patient use and cannot be reused. Reuse of such
devices can be dangerous for both patient and operator.
3.7 Internal Filter
The SA suction unit must have fitted internally a hydrophobic filter capsule to prevent ingress of
foreign material into the pump. The hydrophobic filter prevents costly pump damage as well as
additional protection against contamination from liquids being sucked through due to jar overfill.
Liquid sucked through to the pump motor will cause damage and invalidate the warranty. The filter is
disposable and must not be autoclaved, but renewed in accordance with the recommended
maintenance program.
Warning! A hydrophobic filter must be fitted internally to prevent liquid passing through to
the pump. Hydrophobic filters only work once and should be replaced
immediately it becomes wetted.
3.8 Fluid Collection Containers
The silicon service tube (∅6mm I/D with 3mm minimum wall thickness) must be connected between
the filter and the changeover valve. The changeover valve must then be connected to the vacuum
port on the collection container. These tubes have an elbow connector on one end for fitting to the
filter and for fitting to the ‘VACUUM’ port of the SA 2 collection container. The silicon tubing used in
conjunction with this equipment is a replaceable item. It should be changed regularly according to the
level of usage and where it has become in any way contaminated or damaged.
Warning! All collection containers must be securely mounted when in use.
An anti-foam agent may be put into the fluid collection container, without disinfectant solution, before
use to reduce the possibility of frothing. It should not however, be placed into the container for
extended storage periods.
