Each hose shows how well it conducts static electricity away: conductive (EC), antistatic (AS) or insulating. The source is the NORRES factsheet or test report. A hose is not ATEX-certified in itself. It must always be earthed, and whether it suits a particular zone is decided in your own zone assessment. Insulating hoses must not be used for combustible dust.
Clip profile hoses. Light, compress 4:1 and follow the movements of the arm. Designed for low-vacuum applications.

For extraction arms and suction trucks.

Neither antistatic nor conductive. It can be made static-dissipative by exposing the internal metal wire and connecting it to an earthing point.

Dust in the air needs a large air flow. Dust on surfaces needs a high vacuum. That decides the hose. The vacuum of your machine must not be higher than the hose can take at the diameter you choose.
Match the hose diameter to the machine inlet and the required airflow. A smaller hose gives less air. Example: Depureco DF 22 gives 800, 1,000 and 1,400 m³/h with Ø100, Ø120 and Ø150 mm.
