ASPIRATION GROUP

Designed by Celiber, the aspiration group is composed of:

Metallic support structure:
Galvanized and bent sheet with a thickness of 15/10, riveted and sealed, forming a compact structure, reinforced to give it a high rigidity.
The two panels which make up the mobile hatches that serve to the inspection of the filters and the ventilation section are fixed to the structure with a quick disassembly system, that makes possible easy maintenance.
Every panel has some handles to make the movement easier.

Filter section:
Stainless Steel trays that support 5 filters of 490 x 590 mm, with these characteristics:
Stainless Steel outline. Thickness of 5 mm.
Synthetic filter model VNF/290 with woven fibers progressively structured.
The clean air face printed with the DIN identification and the allowed number.
Effectiveness: 90% gravimetric according to ASHRAE 52/76
Class: “G-3” according to European regulations EN-779.
Welded mesh of 12×24 of 0,7 mm with “V” form and fixing in a sandwich panel the filter.
Final leak to a dirty filter: 20 mm. H2O.

Ventilation section:
The ventilation section is composed of a triple paddle-wheel fan with double aspiration, joint to the motor by belts and pulleys. The fan is fixed with screws.
At the end of the tree of the fan, a pulley is placed and is where the trapezoidal drive belt passes.
The motor is installed on rails that allow easy regulation of the belt’s tension.
Communication between group and Plenum is done by a T connexion with a valve to change the phase (spraying-drying) that is automatically controlled with the analogue control panel.
