Abstract
A filter cleaning device includes a cleaning chamber operable to receive a gas filter to be cleaned, the cleaning chamber having an inlet through which a gas flow can be admitted and an outlet for gas flow leaving the cleaning chamber, the inlet and outlet being arranged such that the airflow is forced to pass through at least a part of the filter when inserted, the filter cleaning device further comprising a mechanical agitation arrangement operable, in one mode of operation, to generate a linear oscillation along an axis of the filter when inserted and, in another mode of operation, to rotate the filter about an axis of rotation.

A filter cleaning device comprising a cleaning chamber operable to receive a gas filter to be cleaned, the cleaning chamber having an inlet through which a gas flow can be admitted and an outlet for gas flow leaving the cleaning chamber, the inlet and outlet being arranged such that the airflow is forced to pass through at least a part of the filter when inserted, the filter cleaning device further comprising a mechanical agitation arrangement arranged to contact at least a part of the filter when inserted and operable in a first mode of operation, to generate only a linear oscillation along an axis of the filter when inserted and, in a second mode of operation, to rotate the filter about an axis of rotation without linear oscillation along the axis of the filter, wherein in the second mode of operation a gas flow is admitted into the cleaning chamber and forced to flow through at least a part of the filter to the outlet.
A method of cleaning a gas filter using a filter cleaning device comprising a cleaning chamber operable to receive a gas filter to be cleaned, the cleaning chamber having an inlet through which a gas flow can be admitted and an outlet for gas flow leaving the cleaning chamber, the inlet and outlet being arranged such that the airflow is forced to pass through at least a part of the filter when inserted, the filter cleaning device further comprising a mechanical agitation arrangement arranged to contact at least a part of the filter when inserted and the method comprising:
- a) generating only a linear oscillation of the filter along an axis of the filter when inserted to agitate the filter for a first period of time;
- b) passing a gas flow through the filter;
- and
- c) rotating the filter, without linear oscillation along the axis of the filter, for a second period of time.
