#CMT# #/CMT# The system (1) has a flat formed fine dust filter (2) made of paper and textile web. A catch unit is provided for directly attaching the filter system on a fine-dust-delivering opening of a printing device i.e. laser printer, where the catch unit is provided at the fine dust filter. The fine dust filter is arranged at a filter carrier (3) provided with the catch unit. #CMT#USE : #/CMT# Filter system for filtering fine dust from exhaust air during copying and printing by using a printer device i.e. laser printer, and color copier. #CMT#ADVANTAGE : #/CMT# The filter is made of paper and textile web, and the catch unit is provided for directly attaching the filter system on the fine-dust-delivering opening of the device, thus filtering the exhaust air in a simple and economical manner without using wet filters, preventing escaping of particles and avoiding settling of fine dust particle in the user lungs, and hence avoiding health damage and reducing discharge of materials injurious to health. The system has versatile flat shape and is attached individually at each device. The device is problem-free and is exchangeable due to extremely low manufacturing costs. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of a filter system. 1 : Filter system 2 : Flat formed fine dust filter 3 : Filter carrier. |
