Type B Ventilation Grille

Type B Ventilation Grille is a marine aluminum rectangular ventilation grille.The range of diameters is from DN100 to DN400. Rectangular ventilation is a method of ventilation and heat dissipation using rectangular openings. In the enclosed space of the ship, air is brought into or out of the rectangular vents through the equipment, so as to achieve the effect of cooling and increasing air circulation.

Overview

Feature:

The design of rectangular ventilation grilles allows air to move in and out over a large area, thus increasing the effectiveness of ventilation.

Rectangular ventilation grilles can effectively lower the indoor temperature, reduce the frequency of using air conditioning and save energy.

Rectangular ventilation equipment itself is less noisy and does not disturb the surrounding environment.

Rectangular ventilation units are generally made of easy-to-clean materials, making them convenient for routine maintenance.
