1.2.1 Optional accessories

Absolute filter (Code art. AA 2627)

The absolute filter permits trapping the finest dust particles which have not been trapped by the primary polyester filter.

If the vacuum cleaner features this specific filter, its filtering capacity will have to be periodically checked.

Important!________________________________________________________________

During these operations, wear individual protection devices such as gloves, protective eyewear and dust mask.

To change the filter, switch off the vacuum cleaner and remove the plug from the power socket, release and remove the upper cap and then loosen nut ( A ).

Remove the absolute filter, place it in a plastic bag, close this and dispose of it according to applicable laws for the type of vacuumed dust.

Besides the absolute filter, depending on the dust to be vacuumed, the following filters are available:

- ANTISTATIC FILTER

For electrostatic dusts

- NOMEX FILTER

For hot dusts up to 240°

- POLYESTER FILTER CAT. C

For very fine dusts

The polyester filters are BIA institute certified.

Removable cyclone (Code AA 2658)

The cyclone is a treated steel cone that separates the filtering chamber from the container.

This is positioned above the vacuum inlet and below the filter.

Its job is to protect the filter from hot or sharp solid bodies and nebulised liquids.

Bag retention ring (Code AA 2655)

This optional can be requested when the vacuumed material is to be collected in a disposable nylon bag fitted in the container. It allows keeping open the nylon bag, which is subject to vacuum, for correct use.
