Telescopic Extraction Arms
Compact and Movable Extraction Arm Systems for Areas with Limited Ceiling Height
Telescopic extraction arms are compact local exhaust solutions for production areas with low ceilings, restricted working space or limited mounting distances. They capture fumes, vapours, gases and light dust close to their source.
The telescopic pipe structure allows operators to adjust the arm length to the task. The arm remains compact when not in use. During operation, it extends to provide the required working reach.
Telescopic Pipe Structure
The nested pipe system provides compact operation and an adjustable working reach.
Suitable for Limited Height
It suits low-ceiling rooms, confined process areas and restricted mounting zones.
Standard, Stainless Steel and ATEX
Standard, AISI 316 stainless steel and antistatic ATEX versions are available according to project requirements.
What Is a Telescopic Extraction Arm?
A telescopic extraction arm is a compact local exhaust component with pipes that move forwards and backwards. It provides a shorter and more controlled movement range than a standard articulated arm. Therefore, it is suitable for rooms with low ceilings, confined process areas and applications requiring installation close to the working point.
The system combines a rotating base plate, telescopic extraction pipes, a hot-fume hood and a wall-mounting bracket. It captures the contaminant close to its source and directs the polluted air to a fan, filter or central exhaust line.
For general design, commissioning and testing principles, review the HSE guide to local exhaust ventilation.
How Telescopic Extraction Arms Work
Position the Arm
Extend or retract the telescopic arm until it reaches the correct distance from the working point.
Move the Hood Closer
Position the hot-fume hood close to the source of fumes, vapours or gases.
Local Extraction
The extraction inlet captures contaminants before they spread into the workplace.
Exhaust or Filtration
The system transfers collected air to the filter unit, fan or central exhaust system.

Get Technical Support for Telescopic Extraction Arm Selection
Selection should consider the ceiling height, required reach, pipe diameter, contaminant type and airflow. Pressure loss, hood design and stainless steel or ATEX requirements must also be evaluated.
