2Operating Manual – Air Cleaner TAC 5000 / 6500 EN
Description of the device
Air cleaners are used to filter the room air. On building sites and
renovation areas high concentrations of dust can arise, for
instance when using angle grinders or during blasting, chiselling
or demolition operations as well as when mixing dry mortar or tile
cement. This dust is to be vacuumed off as close as possible to
the point of origin in order to reduce the pollution of the breathing
air to a minimum.
Depending on the used filter quality it is permissible to employ
devices for the separation of quartziferous mineral dusts, wood
dust, lead-containing dusts, artificial mineral fibres such as old
mineral wool or high-temperature fibres. Application as vacuum
generator for mould remediation and asbestos abatement is also
a possibility. In case of other hazardous substances, further
requirements may result from HAZMAT regulations
(Please observe the applicable TRGS [Technical Rules for Hazard-
ous Substances] or provision!).
TAC air cleaners are therefore ideally suited for:
• producing a vacuum in a room, e.g. heavily contaminated
spaces;
• producing overpressure in a room, e.g. cleanroom;
• air purification in workspaces via air circulation, e.g. indoor
building sites, workshops etc.;
• supplying filtered fresh air.
The air cleaners TAC 5000 and TAC 6500 are basically made up
of the following:
• housing with stacking aid
• set of wheels with at least 2 swivel castors with brake
• boxes for pre-filter and main filter
• filter monitoring each for pre-filter and main filter
• fan with speed control
• Flowmatic for constant volumetric flow control
Filterboxes
The filterboxes can be fitted with various air filters depending on
the application or requirement:
• Filterbox 1: coarse filter (Z-Line G4) and/or
fine filter (pleated M5 to F9)
•Filterbox2:HEPAfilter
(E10…H14 or dust class M to dust class H)
alternatively:
• Filterbox 2: bag filter (M5 to F9),
in that event the fine filter in filterbox 1 can be omitted
The filterboxes are made of aluminium sheet and powder-coated.
Filter types (not included in the scope of delivery)
The designated air filters are especially geared to our devices and
come with the largest possible filter surface based on the
geometric dimensions. This ensures maximum air flow rate and
lifetime for safe operation.
Filter monitoring
Monitoring is effected respectively for the pre-filter (filterbox 1)
and main filter (filterbox 2) by means of individual differential
pressure switches. These are integrated in the fan box.
Settings:
• Filter 1 = 300 Pa
• Filter 2 = 650 Pa
The alarm is indicated both visually and acoustically via warning
lights (filter 1 and filter 2).
Flowmatic
The Flowmatic is a configurable differential pressure transmitter
with display. It serves to analyse the measured differential pres-
sure at the fan's injection nozzle. The specific nozzle factor (K
value; depending on the type of nozzle) is used to convert the dif-
ferential pressure to volumetric flow and to display it. At the same
time the current value is transmitted to the fan's internal control-
ler via a standard signal (0…10 V).
The controller now compares the actual value with the nominal
value preset by use of the speed controller and compensates the
discrepancy by lowering or raising the engine speed. Should the
maximum engine speed be reached and the volumetric flow still
be too low, it cannot be compensated.
