Product catalog summary

Introduction
The SQR series dampers are designed for controlling air flow volume and pressure in air-conditioning, ventilation, and heating systems. They feature opposed blades of 100 mm.

Specifications
The dampers are classified into several types based on blade profiles and orientations:

SQR-EH: Rhomboidal profile blades parallel to the largest side (L size).
SQR-EV: Rhomboidal profile blades parallel to the shortest side (H size).
SQR-BH: Flat profile blades parallel to the largest side (L size).
SQR-BV: Flat profile blades parallel to the shortest side (H size).
SQR-ECC: Square damper with rhomboidal profile blades and circular connections.
SQR-BCC: Square damper with flat profile blades and circular connections.

Materials
The dampers are constructed with a "U" shaped extruded aluminium frame, aerodynamic aluminium blades with rubber seals, and galvanized steel components for the axle and protection sheet. High resistance bearings and external gear transmission are used to prevent dirt accumulation.

Accessories
Available accessories include:

/FC/: Free-cooling kit for assembling two dampers at 90 degrees.
M5, M10, M15: On/Off actuators at 24/230V with varying force (5N, 10N, 15N).
MC5, MC10, MC15: On/Off actuators with auxiliary switches.

Fixing Systems
The damper frames are designed to be jointed with rivets in ducts or flat surfaces. Various sizes and configurations are available to suit different installation requirements.

Finishes
The dampers are available in raw aluminium finish.

Performance
Performance metrics include face velocity, pressure loss, and sound power level, with specific data provided for different series and configurations.
