Isophthalic acid is a base substance for aramides, polyester, synthetic resins for high-temperature-resistant electrical insulating coatings and oilfree alkyd resins. The technical synthetic materials distinguish themselves in particular by their high strength, thermal resistance, very good electrical insulating power and a high wear resistance. Leading manufacturer is a company based in Switzerland.

Infastaub supplied for dedusting of two pneumatic pressure conveyings two silo vent filters type Infa-Mini-Jet AJM to this company. Because of the flammability of isophthalic acid, the preventive explosion protection was specified by inertisation with nitrogen. Special feature is conveying and filter cleaning with nitrogen. That‘s why the filters are designed gastight.

The bag filters reduce the residual dust content in the clean gas area below 2 mg/m³.
