HOSPIVAC – MEDIVAC EVISA E25

INTRODUCTION

Please ensure you are familiar with the operating instructions prior to commissioning your
vacuum plant. Damage which may arise from incorrect siting or installation is not covered
by our guarantee.
In order to simplify any future requests for spare parts or further information about your vacuum unit, we
advise you to copy onto this page the specifications written on the plates fixed to the vacuum unit, as soon
as you receive your machine.

DESCRIPTION

An HOSPIVAC vacuum unit can consist of:
 One vacuum pump and one attached receiver:
 Two vacuum pumps and one attached receiver:
 Three vacuum pumps and one attached receiver:
 Three vacuum pumps on framework :
 4 to 6 vacuum pumps on framework (E100 / E200 / E300) :
 1 to 6 vacuum pumps on base
 4 to 6 vacuum pumps on 2 framework on parallel
 8/10/12 vacuum pumps on base, working couple there
2.1.

Vacuum pumps

HOSPIVAC and MEDIVAC vacuum plants are mounted with EVISA E vacuum pumps.
2.2.

Receivers

The receivers are made and designed especially for vacuum.
If the FLEXO regulation control has been selected:
 For HOSPIVAC 1, 2 or 3 units, the capacity of the main attached receiver is sufficient.
 For HOSPIVAC G and V plants, select the receiver according to the number of vacuum pumps.
If the ON/OFF regulation control has been selected, a secondary receiver is supplied separately, in order to
comply with AFNOR standard NFS90 155 which specifies a reserve capacity, calculated according to the plant
capacity. AFNOR standard NFS90 155 indicates the following method for calculating the total capacity of the
receivers necessary for your installation.
"The calculation of the buffer chamber volume must take account of requirements, but also the pump
discharges and hence the number of times they are started up per hour. For example, for
mbar, i.e. with the unit actually set at between 650 mbar and 850 mbar, the buffer chamber will have a
volume in cubic meters corresponding roughly to the rated discharge of the pumps in cubic meters per minute
(for two 60 m³/h vacuum pumps, i.e. 1 m³/min per pump, a 2 m³ chamber is needed)."

The so-called "secondary" receiver will be installed as a "dead-end" on the main pipe work. It will enable the
plant to be correctly controlled. This secondary receiver can be fitted close to or a long way from the main
receiver without any problem.
2.3.

Filtration and delivery pot

An antibacterial filtration unit traps bacteria before they reach the receivers and the vacuum pumps.
She can be:
 An either single antibacterial filtration with BY-PASS consisting of a main filter: when replacing the
cartridge of the filter in by-pass mode, the air is not filtered and the pump(s) may temporarily become
polluted.
 Or a DUPLEX PARALLEL antibacterial filtration consisting of two filters in parallel, running simultaneously.
During replacement of one cartridge, the secondary filter provides filtration, so in this case the pump(s)
is (are) constantly protected.
Our main bacteria filters consist of a pot/opaque filter containing a special bacteria cartridge fitted with a
deflector. This filter is opaque to prevent bacteria from proliferating in the filter element. The cartridge is
made of micro fibres bound with borosilicate, and its filtration fineness is approximately 1/100th of a micron.
This cartridge passes the so-called sodium flame test. Penetration of bacteria and living microorganisms is
well below 0.05%, a value generally demanded by standards in various countries. A sterilizable transparent
Pyrex bottle is screwed to the base of the filter units.
An exhaust pot is placed on the exhaust circuit, located at the lowest point. Its purpose is to catch
condensation produced in the exhausted gas evacuation duct.
2.4.

Electrical box

One electrical cabinet combines the motor control and protection systems.
Several types of control are available, depending on individual use:
 PROCOM-2 microcomputer to control between 1 and 6 pumps with sensor regulation,
 CYCLIC 2020 electronic system to control 2 or 3 pumps A, B and C with sensor regulation,
 MILLENIUM automatic system to control 2 or 3 pumps A, B and C with sensor regulation.

OPERATION

The air conveyed by the vacuum network passes through the main bacteria filter, enters the main receiver
and is then sucked by the vacuum pump(s) of the vacuum unit/plant.
The exhaust system consists of an exhaust hose fitted with a condensate collecting pot on a by-pass at the
lowest point of the network.
The pumps include a built-in check valve and, for added safety, a second check valve has been fitted. This is
located between the pump hose and its inlet into the receiver.
