GFAP high-pressure jet filters are designed for systems requiring air filtration and dust removal before being reintroduced into the environment, typically in pneumatic conveying systems or suction plants. Filtration occurs through cyclonic settling followed by the passage of air through filtering sleeves. Compressed air (6–7 bar) is stored in one or more external tanks. An electronic timer cyclically opens the solenoid valves connected to the tank, channeling the air into pipes with special holes that generate a high-pressure reverse jet inside the filtering sleeves, with the purpose of detaching the dust deposited on their outer surface. The bottom can be either conical or flat; in the latter case, a motorized scraper is used. Dust is discharged through a rotary valve. Maintenance is facilitated by large access doors and a quick system for replacing the filtering sleeves.
