1.2 General description
The LMA 75 is a compact flexible arm, which is ideal for all
types of smaller dust and fume applications.
The arm is fitted with exterior friction joints, which allows for
maximum air velocity, low pressure drop and low noise level.
The inner tubes are kept in place by a gas spring (standing
arm) or a balancing strap (hanging arm). This design ensures
smooth movement of the arm.
The LMA 75 arm is available in two different types:
- for hanging mounting
