The brand-new AD EX range from sister company Absolent delivers fully ATEX rated dust and fume extraction, engineered for production environments where safety and compliance matter most.

The new range comprises three models, the AD051EX, AD101EX and AD151EX - each certified for installation in ATEX Dust Zone 22, and suitable for dust explosion classes ST1, ST2 and ST3. With airflow capacities from 1,200 to 13,500 m³/h, the range scales from smaller process environments through to large-scale industrial installations.

Proven Vertical Airflow Technology

At the heart of the AD EX range is Absolent’s proprietary Vertical Airflow Technology, which delivers a downward contaminated airflow pattern through vertical filter elements combined with a downflow pulse-jet cleaning system. This design achieves high pre-separation, directs dust efficiently to the collection hopper and minimises accumulation on filter elements - resulting in stable, long-term performance, extended filter service life and reduced maintenance requirements.

Flexible Explosion Protection for ATEX Compliance

The AD EX range offers multiple explosion protection configurations to suit site-specific safety requirements, available space and process risk:

• Explosion relief panels - for external or open installations
• Explosion panels with flame diverters - redirecting energy safely away from personnel and equipment
• Flameless vents - for indoor or space-restricted environments where external venting is not possible

Three types of filter media (eco polyester, standard polyester and polyester nano fibre) are available in anti-static versions for full ATEX compliance or can be selected in non-ATEX versions if handling statically charged dusts.

Safer, Simpler Maintenance with CleanChange™

A key innovation in the AD EX range is Absolent’s unique CleanChange™ filter replacement mechanism, which allows filter cartridges to be accessed and removed from the clean side of the unit — without tools and without entering the contaminated section. Combined with a quick-release access door incorporating a system safety switch, this significantly reduces operator exposure during maintenance and minimises production downtime.

Low Total Cost of Ownership

On-demand pulse-jet cleaning, optimised airflow design and optional inverter-controlled fans work together to minimise energy consumption while maintaining consistent filtration performance. Units are constructed from Galfan pre-coated steel which offers twice the corrosion resistance of conventional hot-dip galvanising - ensuring long-term durability in demanding industrial environments and contributing to a low whole-life cost.

Ideal for Industries Handling Combustible Dust

The AD EX range is suited to a wide range of industries and processes where combustible dust is generated, including:

• Food and beverage processing
• Pharmaceutical and chemical manufacturing
• Plastics, composites and textiles
• Metal fabrication, welding, grinding and laser cutting
• Building products and minerals
• Packaging and converting

“The AD EX range represents a significant step forward for customers operating in ATEX classified environments,” comments Filtermist’s Global Commercial Director, Graeme Bell.

“It combines proven Absolent filtration technology with the flexibility and compliance that industry demands. As part of Absolent Air Care Group, Filtermist is uniquely placed to provide expert specification support, installation and ongoing aftermarket care for the AD range, as well as our Dustcheck dust collectors and process filters.”
