LINEAR GRILLES

Product catalog summary

Linear Grilles Overview

Description: This document provides detailed information on various types of linear grilles, specifically models LM1, LM2, and LM3, which feature different blade angles of 15º and 35º. These grilles are designed for use in HVAC systems for both air supply and return.

Material: All grilles are constructed from extruded aluminum frames and blades, ensuring durability and performance.

Application: These grilles are suitable for both cooled and heated air supply, with minimal temperature differences, and can be installed on walls, floors, or window sills.

Finishing: The standard finish is natural anodized, with an option for electrostatic powder coating. Standard colors include RAL 9010 and RAL 9016, with additional colors available upon request.

Installation: Standard installation involves screws, with options for clips and plate springs if frame holes are not desired.

Accessories: Available accessories include dampers (PKD and ZKD), plenum boxes (PK), subframes (KK), and synthetic filters (EU2-EU5).

Standard Sizes: Grilles come in various metric sizes, with widths ranging from 250mm to 1500mm and heights from 50mm to 600mm.

Frame Types: Frame sizes available are 17mm, 22mm, and 32mm.

Selection Tables: Detailed tables provide data on effective area and air velocity for different grille sizes and types (LM1, LM2, LM3).

Diagrams: Supply and return selection diagrams for each grille type (LM1, LM2, LM3) are included to aid in proper selection and installation.

Sample Grille Selection: An example is provided for selecting an LM2 blade based on specific air volume and room dimensions.

Technical Specifications and Mounting Details

Overview: The document outlines technical specifications and mounting details for linear grilles used in HVAC systems, focusing on models LM1, LM2, and LM3. It includes information on air fall selection, temperature changes, and mounting options.

Air Fall Selection: Air fall is defined as the vertical distance between the air drop center and the lowest point, calculated using the formula Ld = Lds + Ldt. The document also discusses temperature changes (TL/TZ) and induction (I).

Mounting Details: Three mounting methods are outlined: screw mounting, clips mounting, and spring mounting, each with specific installation details.

Mounting Hole Placement: A table indicates the placement of mounting holes based on grille width and length, with codes (A, B, C, D) representing specific configurations.

Plenum Box Mounting: Details for top entry and side entry plenum box mounting are provided, essential for proper grille installation.

Order Code Explanation: The document explains the order code system for linear grilles, detailing blade types, frame sizes, mounting options, damper types, and coating options. For example, 'LM1 28 PKD RAL9010 VD W 300X200' specifies a grille with a 28mm frame, parallel blade damper, powder-coated finish, and screw mounting.
