ATEX extraction arms as part of a safe extraction system
ATEX extraction arms are used in applications where explosive atmospheres caused by combustible dusts, gases, or vapors may occur. Key factors in selecting the appropriate system include the operational risk assessment, zone classification, substance data, and the suitability of the entire extraction system.

Equipotential bonding and electrostatic charging
Conductive or dissipative components and connections must be integrated in accordance with the protection concept. Replacement hoses, adapters, or other retrofitted components must not interrupt the intended equipotential bonding.
Flow rate, Diameter, and Range
The diameter must be appropriate for the required air volume and the necessary flow rate. As the hose length increases, pressure loss and mechanical demands rise. Long versions therefore require suitable mounting and sufficient power reserve from the downstream system.
Important Planning Data
✔ Zone and required equipment category
✔ Type of dust, gas, or vapor and material data
✔ Flow rate and transport velocity
✔ Reach, range of motion, and mounting point
✔ Potential equalization and grounding concept
✔ Suitability of filters, fans, and ductwork
The overall system is what matters
The extraction arm transports the contaminated air through piping to the filtration unit. Therefore, the fan, filter, piping, discharge, grounding, and, if necessary, additional explosion protection measures must be evaluated together.
FAQ
Is an ATEX extraction arm sufficient for an ATEX-compliant system?
No. What matters is the suitability of the entire system.
Does the extraction arm need to be grounded?
The required equipotential bonding depends on the protection concept and the risk assessment.
Can a damaged hose be replaced with any other hose?
No. The material, conductivity, dimensions, and technical suitability must be appropriate for the intended application.
What is a reasonable reach?
Only as long as necessary for the actual work area, since additional length increases pressure loss and operating forces.
Consulting on ATEX extraction arms
For the preliminary selection, we need the zone, material data, process, range, connection diameter, and details about the existing extraction system.
