Air filter and module to be used for building up such a filter. |
摘要 |
<p>An air filter of which the dimensions may be easily adapted to the shape and dimensions of air ducts, especially air ducts of air condition equipments, comprises a number of frame shaped modules (1) made of plastics material. To each module a filter bag (2) is welded. The side faces (1a, b, c, d) of each module are provided with a system of ribs (5) or embossments (6). For joining modules substantially airtightly together a system of ribs or embossments on a side face of a module is connected to a complementary shaped system of ribs or embossments on the side face of another module by sliding movement or snap action. Preference is given to an embodiment whereby inclined side boundaries of interengaging complementary systems form a dovetail connection.</p> |
