ONE PRODUCT · FOUR SIZES
One family, the right diameter.
AT-100, AT-125, AT-160 and AT-200 are size options within the ATEX extraction arm family, not four separate product listings. Diameter and length are selected for airflow, reach and system pressure loss.

Specifications are published for AT-160 and are not assumed for the other diameters.
ENGINEERED FOR HAZARDOUS AREAS
ATEX design, application fit.
An II 2GD ATEX category is listed for this product family for gas and dust atmospheres. The hazardous-area classification, handled substance, temperature and connected extraction system must be assessed together.
Antistatic flexible duct
Wire-grounded flexible duct designed to help control electrostatic charge accumulation.
Stainless-steel construction
The AT-160 manufacturer description specifies an AISI 304 body and hood.
Manual damper
Integrated damper for manual regulation of extraction airflow.
Hydraulic movement
Hydraulic-assisted positioning and stable placement as described by the manufacturer.
ATEX suitability and facility safety depend on the selected unit documentation and engineering assessment of the entire extraction system.
APPLICATION AREAS
Capture contaminants at the source.
Chemical & pharmaceutical
Local capture of dust, gases or vapours near process handling and mixing points.
Defence & metalworking
Local extraction in grinding, machining and other potentially hazardous particulate processes.
Painting & industrial processes
Adjustable source extraction where site hazard classification and system design allow.
VENSIS ENGINEERING
Share the process, select the diameter.
An extraction arm is not a fan or dust collector. Airflow and total system pressure drop must be considered when choosing the connected fan and filtration solution.
- ✓Contaminant type: gas, vapour, dust or fumes
- ✓Area classification and ATEX requirements
- ✓Required reach and arm length
- ✓Airflow and duct connection
- ✓Quantity, mounting point and project location
FREQUENTLY ASKED QUESTIONS
About ATEX extraction arms.
Are AT-100, AT-125, AT-160 and AT-200 separate products?
No. This page treats them as nominal diameter variants of a single ATEX extraction arm family.
Does the extraction arm generate suction by itself?
No. The arm is a local extraction component and requires a compatible extraction fan and, where necessary, a filtration system.
What does ATEX II 2GD mean?
It is the equipment category stated by the manufacturer for gas and dust applications. Suitability depends on the selected configuration documentation and installation conditions.
What are the published AT-160 specifications?
The AT-160 listing specifies Ø160 mm, recommended airflow 1,200–2,000 m³/h, pressure drop 400–800 Pa, and lengths of 2, 3 and 4 metres.
How is the price determined?
Pricing depends on diameter, length, quantity, installation and ATEX details. No fixed price or stock commitment is shown.
