Product catalog summary
Introduction
The document provides technical specifications and details for the MG series of circular single blade regulating dampers, designed for regulating air flow in air-conditioning systems. These dampers can be used in both rigid and flexible circular ducting.

Specifications
The MG dampers are available in zinc plated steel or stainless steel, with options for nylon or brass shaft bushes. They can be manually adjusted or fitted with a motorisable control for automated operation. The dampers come in two main versions: MG/1 (without flange) and MG/2 (with flange), with further variations in material (zinc plated or stainless steel).

Dimensions
The dampers are available in various nominal diameters ranging from 80 mm to 800 mm, with a standard length of 200 mm or 300 mm depending on the diameter.

Technical Data
The document includes detailed technical data such as effective outlet area, weight, pressure loss, and noise rating. The pressure loss and noise ratings are provided in relation to air flow rate and blade inclination angle.

Installation and Fixing
For MG/1 dampers, fixing is done using a nipple joint and self-tapping screws for rigid ducts, or clamps for flexible tubing. MG/2 dampers are fixed using bolts through the flanges.
