The two resp. three lobe
vacuum pumps provide a maximum under pressure of 400
mbar at a suction volume of 600 to 2800 m3/h. The required
suction volume depends on the number of machines to
be cleaned simultaneously.
The power of the drive motors exceeds the power demand
at the drive shaft of the pumps, which are operated
oil free and non-contact.
Jointly with the additional fine filter this ascertains
highest operation safety with reduced maintenance.
In order to save energy cost the vacuum pump is switched
off whenever the system is not used within a pre-set
time. Instead of this power-down, we optionally offer
part-load or stand-by operation which will provide a
minimum vacuum with least energy input. Full efficiency
will fast be available, as soon as suction points are
The size of the combined filter and collection receiver
depends on waste quantity and required suction volume
(980 mm dia, lengths 1750-3000 mm). JACOBIs filter
medium is a particularly developed needle felt with
high degree of separation at high air permeability.
On opening the aeration valve, the filter is automatically
cleaned by flow-back air. Return of clean exhaust air
into working rooms for heating purposes is possible.
One only staff is required to manually discharge the
filtering and collection receiver. When equipped with
automatic discharge, the system is ready for re-start
in less than a minute.
