dryhazardous dustdust

Presentation The 452 AIREX 14V 1/3D is an ATEX industrial vacuum designed for zones 20 (indoor) and 22 (outdoor). It is a non-electric unit operating with compressed air via a multi-nozzle venturi system, mounted in a stainless-steel head, intended for the safe extraction of combustible and hazardous dusts. The unit bears the CE EX 1/3D marking and complies with the European standard UNI EN 17348:2022.

Functional summary Venturi compressed-air vacuum for ATEX dust extraction with dual filtration (antistatic M-class pocket filter + HEPA H14 absolute filter), 45 L stainless-steel tank, multi-nozzle venturi head, manual filter cleaning by handle, mobile on casters.

Key features

• Complete filtration system (antistatic polyester M-class pocket filter + HEPA H14 absolute filter).
• Venturi technology powered by compressed air, no electrical supply required (operating at 6 bar, air consumption 1458 Nl/min).
• ATEX certified for zones 20/22 for combustible dusts (marking II 1/3D Ex h IIIC T80°C Da/Dc).
• Compact, mobile and suitable for construction sites, confined areas and sensitive environments.

Detailed description The 452 AIREX 14V 1/3D uses a multi-nozzle venturi system housed in a robust stainless-steel head to generate strong suction without an electric motor. Operating at 6 bar with an air consumption of 1458 Nl/min, it provides a maximum vacuum of 3700 mmH₂O and a maximum airflow of 300 m³/h (airflow doubled compared with the 7V version). The design targets efficiency where dust volumes are significant or dispersed.

Filtration and safety Filtration consists of:

• An antistatic polyester M-class pocket filter, filtration area 20000 cm², designed to retain dry, fine and flammable dusts.
• An absolute HEPA H14 filter with 20600 cm² area (almost twice the size of the 7V model), providing 99.995% efficiency down to 0.18 μm.

Dual filtration ensures purified outlet air compliant with safety requirements. Filter cleaning is manual and activated by a handle for quick maintenance without disassembly.

Design and use 45 L stainless-steel tank, mounted on casters and easily detachable. The unit is compact and ergonomic, with weight and footprint optimized for use in confined spaces and restricted areas. Moderate noise level (68 dB(A)). Suited to professionals who must vacuum flammable dusts in constrained environments while maintaining safety and manoeuvrability.
