During the manufacture of writing instruments and cosmetic pens, the wooden casing is sharpened on milling machines. The wood chips produced in this process are extracted from the machines and separated in a central INFA-JET dust extraction unit. Downstream of the filter is a briquetting plant where the chips are compacted.

Note:

In accordance with the requirements of BGI 730, the filter housing is equipped with a fire extinguishing system and bursting discs.

Technical specifications

An MPR cartridge filter with two filter stages is used for dedusting a coating system. The filter system is designed for a volume flow of 4,000 m³/h with a raw gas dust load of max. 5 g/m³. The filter media have a filter area of 60 m² per filter stage and are made of antistatic polyester spunbond fabric or, in the second filter stage, micro glass fiber fleece (class H14 according to DIN EN 1822). For process engineering reasons, the filter media are only cleaned after the coating process. The filter media are changed using the "Safe Change System" (bag-in-bag-out) with a change collar, and the dust is discharged via a dust-tight, closable continuous bag system that opens into existing customer barrels (200 l).

Potential dust explosions are prevented by inerting with nitrogen during the process, which places high demands on the tightness of the filter system. With a residual dust content of 0.001 mg/m³ and the bag-in-bag-out system, the filter system contributes to the process quality during film coating and reliably protects the working environment from contamination.

An INFA-MICRON MPR cartridge filter ensures clean production of medicines by collecting dust at several extraction points within a tablet press. Thanks to the two-stage filter system, a residual dust content of 0.001 mg/m³ is achieved in the exhaust air at a volume flow of 1,300 m³/h and a raw gas dust content of 5 g/m³. The filter cartridges of the first filter stage achieve IFA dust class M, while those of the second filter stage achieve class H13 according to DIN EN 1822. The Safe-Change system ensures that filter media and dust collection pots can be changed without releasing dust into the environment. This protects employees and the environment when handling active substances.

An AJLS lamella filter with two filter stages is used for dedusting a coating system. The filter system is designed for a volume flow of 4,000 m³/h with a raw gas dust load of max. 5 g/m³. The filter media in the first filter stage are made of antistatic polyester spunbond fabric, and in the second filter stage of micro glass fiber fleece (class H14 according to DIN EN 1822). For process engineering reasons, the filter media are only cleaned after the coating process. Possible dust explosions are prevented by inerting with nitrogen during the process, which places high demands on the tightness of the filter system.
