Title (EN) METHOD AND ARRANGEMENT FOR CLEANING ONE OR MORE AIR FILTERS
(FR) MÉTHODE ET DISPOSITIF DE NETTOYAGE D'UN OU DE PLUSIEURS FILTRES À AIR
Abstract: front page image
(EN)The invention relates to a method of cleaning one or more air filter elements (100) with a cleaning arrangement (1) comprising a rotatable basket (20) for holding the one or more air filters, a spraying device (30) for spraying cleaning fluid into the basket, and a driving unit (40) for driving the basket into rotational motion. The method comprises placing the one or more air filter elements in the basket, and performing at least three cleaning cycles. A cleaning cycle comprises the following steps. First the rotation of the basket is driven up to a rotational speed at which the one or more air filter elements have a speed greater than about 15 m/s, preferably greater than about 20 m/s. Then the rotation of the basket is brought back to a rotational speed at which the one or more air filter elements have a speed below about 2 m/s. In addition, the cleaning cycle comprises spraying cleaning fluid into the basket during at least a portion of the cycle.
(FR)L'invention porte sur une méthode de nettoyage d'un ou de plusieurs filtres à air (100) au moyen d'un dispositif de nettoyage (1) qui comprend: un panier tournant (20) recevant un ou plusieurs filtres à air; un dispositif de pulvérisation (30) pulvérisant un fluide de nettoyage dans le panier et une unité (40) entraînant le panier en rotation. La méthode consiste à placer le ou les filtres à air dans le panier, et à effectuer au moins trois cycles de nettoyage. Un cycle de nettoyage comporte les étapes suivantes: mise en rotation du panier jusqu'à une vitesse supérieure à environ 15 m/s, et de préférence supérieure à environ 20 m/s; et retour de la vitesse de rotation à moins d'environ 2 m/s. Le cycle de nettoyage comporte en outre la pulvérisation d'un fluide de nettoyage dans le panier pendant au moins une partie du cycle.
