Definitions
- the invention relates to a filter for gaseous media contaminated with moisture and / or oil and / or solid particles, having a housing having an inlet and an outlet for the gaseous medium and a pot-shaped filter element accommodated therein, the filter means of which is arranged between the inlet and the outlet ,
- the inlet opens axially into the cup-shaped filter element which is generally open at the top and closed by a cap at the bottom.
- the medium to be cleaned is thus forced to flow through the cylindrical wall into the chamber of the housing and from there to the outlet.
- Moisture particles, oil particles and / or solid particles are retained by the filter medium of the filter element.
- more or less moisture is separated due to the coalescence effect and drips down into the housing, where it can be removed via a condensate drain.
- the invention has for its object to provide a filter with a cup-shaped filter element, based in particular on the coalescence effect, which has a long service life.
- a filter of the type mentioned at the outset in which a pre-filter designed as a cyclone filter with a coalescence effect is interchangeably arranged upstream of the filter means.
- the filter according to the invention because of the easily replaceable pre-filter, essential parts of the substances contaminating the medium to be cleaned are filtered out, so that the service life of the main filter which is decisive for the filter performance is considerably extended. This also leads to cost-effective operation, because the main filter, which determines the filter performance, entails much higher procurement costs than the easily replaceable but also easy-to-clean cyclone filter.
- the filter means has the shape of a hollow cylinder, in the upper end of which the pre-filter is seated, which is designed as a hollow cylinder open at the bottom with a swirl generator arranged at its upper open end.
- the filter medium of the pre-filter should have a coalescing effect.
- the invention is explained in more detail below with reference to a drawing which represents an exemplary embodiment.
- the drawing shows the filter in axial section.
- the filter shown in the drawing has a housing which consists of a head 1 with an inlet 2 and an outlet 3 and a pot 4 which can be connected tightly to the head 1.
- the inlet 2 opens axially and centrally in the pot 4, while the entrance to the outlet 3 is eccentric.
- a pot-shaped filter element 5 is accommodated coaxially in the pot 4.
- the filter element 5 has a closed bottom 5a and a hollow cylindrical filter means 5b and a head 5c, with which it is tightly connected to the head 1 of the housing, so that the medium to be cleaned enters the interior of the cylindrical filter element and is forced, the cylindrical To flow through the wall of the filter medium 5b.
- the filter element 5 is preceded by a pre-filter 6 in the form of a cyclone filter with a coalescing effect.
- the cyclone filter consists of a cylindrical filter means 6a open at the bottom and a swirl generator ⁇ b arranged at the upper end in the form of guide vanes. The arrangement is such that the gaseous medium flowing in via the inlet 2 is forced to pass the swirl generator 6b.
- the essentially linear flow turns into a rotating flow implemented so that when the gaseous medium travels further through the hollow cylindrical filter means 6a, liquid particles and solid particles are deposited on the filter means ⁇ a, in particular using the coalescence. This means that only the remaining impurities in the gaseous medium have to be filtered out by the main filter 5.
- the service life of the main filter 5 is therefore correspondingly longer.
- the exchangeable prefilter 6 should consist of an inexpensive and / or easy-to-clean filter material, so that the operating costs of the filter remain low even when the prefilter 6 is changed frequently.

Abstract
La présente invention concerne un filtre destiné à des milieux gazeux, pollués par de l'humidité et/ou de l'huile et/ou des particules solides. Un élément de filtre (5) en forme de pot est pourvu dans un boîtier (1, 4), entre l'orifice d'entrée (2) et l'orifice de sortie (3). Un préfiltre (6), qui est facilement démontable et fonctionne selon la technique d'un filtre cyclone, est placé à l'entrée dudit élément de filtre (5). Le filtre selon cette invention permet de réduire les frais d'exploitation, en ce que la durée d'utilisation du filtre proprement dit est longue et en ce que le préfiltre facilement remplaçable n'engendre aucun coût important.
