GCL-ATEXzn 20-21-22 Filters

Self-cleaning filters for combustible dust used in explosion-risk applications.

The GCL-ATEX filter is a high-efficiency self-cleaning filter equipped with an online automatic cleaning system using compressed air jets. This filter was designed by Giannozzi Srl to address the specific challenges related to handling emissions from potentially explosive atmospheres, in compliance with European ATEX Directive 2014/34/EU.

The ATEX sleeves filter for explosive dust features a sealed structure made of reinforced material capable of withstanding high pressures resulting from possible explosions. The joint flanges are also equipped with clamps that ensure equipotential continuity.

Depending on the classified area of use, the filter is equipped with specific components sized for operation in potentially explosive atmospheres.

ATEX bag filter for explosive dust: the components

The GCL-ATEX filter has a sealed structure made from reinforced material, designed to withstand high pressure caused by potential explosions. The joint flanges are fitted with clamps that ensure equipotential continuity.

Based on the classified zone, the filter includes specially dimensioned components for safe use in explosive atmospheres.

The main components of the ATEX filter include:

• Non-return valve = installed on the inlet duct to prevent explosion propagation within the suction line
• Bursting panel = designed to relieve pressure from an explosion and protect both the filter structure and the surrounding area
• Rotary or screw discharge valves with high ATEX-compliant protection level
• Explosion-proof differential pressure switch for detecting clogging in the filter sleeves.
