Home General catalogue Air Diffusion Grilles Ega 1 4 Exhaust Aluminium Grilles 25 Mm Pitch With Filter

Description

Exhaust grilles with fixed horizontal blades inclined by 45°, with the insertion of a special profile or counter-frame that allows for a flat filter for coarse or fine dust to be housed.

Characteristics

Material: aluminium.
Finish: natural anodised.
Filter: COARSE class (G2) thickness 12 mm.

Installation

Installation is carried out by opening the special brackets in the counter-frame or, alternatively, by securing the latter to the wall or duct using screws.

EGA1 - EGA2: for wall installation only, ceiling installation is not recommended. Closing with magnet.

EGA3 - EGA4: closing with screw.


Use

For external or indoor air exhaust where dust pre-filtration is recommended.
Initial pressure drop lower than 40 Pa with 1.5 m/s speed on the filter.

Models

EGA1: grille with filter;
EGA2: grille with filter and damper;
EGA3: grille with special counter-frame secured with a hinge to the grille frame to allow for easy filter maintenance;
EGA4: grille with damper and special counter-frame secured with a hinge to the grille frame to allow for easy filter maintenance.

Accessories

- EPZ galvanised plenum;
- EPI insulated plenum;

Operating data

m³/h: flow rate
Pa: pressure drops in Pascal
dB(A): noise level
V: face velocity on the filter (m/s)
An air velocity on the filter of 1.5 m/s is recommended to contain pressure drops and maintain filtration efficiency;
the flow rate data in the table refers to the grille with the filter.
All dimensions are expressed in mm
