Why choose double-layer grille air vents

In HVAC systems, the structural design of the air vents will directly affect the air supply direction, air distribution, indoor comfort and system operation effects. Ordinary single-layer air vents have a relatively limited range of airflow adjustment, while double-layer grille air vents can achieve more flexible airflow direction control through the front and rear two-layer blade structure.

Double-layer grille air inlets are suitable for places with requirements on air supply direction, air volume adjustment and indoor air flow organization. It has a stable structure, clean appearance and easy installation. It is a commonly used terminal air outlet product in ventilation and air conditioning systems of commercial buildings, medical buildings, laboratories, clean rooms and industrial plants.

Main features

Double-layer blade structure

The front and rear double-layer grille blade design can realize multi-directional airflow adjustment and facilitate the control of the air outlet direction according to on-site needs.

Flexible air flow adjustment

The angle of the front and rear blades can be adjusted according to needs, which helps improve air distribution and reduce local uneven air supply or direct air blowing problems.

Stable ventilation effect

Reasonable grille structure and blade spacing help air circulate smoothly, reduce wind resistance, and improve the operation effect of the ventilation and air conditioning system.

Simple and beautiful appearance

The product has neat lines and a flat surface. The overall appearance is simple and elegant, and can be coordinated with the ceiling, wall or equipment panel.

Easy to install

The structure is reasonably designed and can be used for ceiling installation, wall installation, air duct end installation or equipment supporting installation, and on-site construction is convenient.

Flexible material selection

It can be made of aluminum alloy, galvanized steel plate, stainless steel and other materials to meet the requirements of different environments for weight, anti-corrosion, strength and appearance.

Various surface treatments

Surface treatments such as spraying, anodizing, and stainless steel wire drawing can be carried out according to customer needs. White, gray, black or other specified colors can also be customized.

Can be equipped with regulating valve or filter screen

According to system requirements, air volume regulating valve, filter screen or other accessories can be configured to meet the functional requirements of different ventilation and air conditioning systems.
