Previously, we share cutting machine and welding machine for air grille diffuser production. You know only know more about VENTECH machine, you may also get new ideas on how to optimize the production technique. Apart from cut and weld process, we do assembly to finish a product. Now let’s share more!

VENTECH owns a 15 years air outlet factory and a machinery factory. We have technical R&D team, focus on air diffuser grille machines.

1.Material entry preparation
(1)The materials entering the project must meet the project quality regulations and technical requirements. The steel nameplate is clearly visible, and the relevant certificates, inspection reports, and factory certificates are complete.

(4) The vertical edges of each air duct connection should be aligned, the position of the sealing strip should be correct, and the sealing ring screws should be tightened to ensure that the entire circumference is even and tight.

Fume Hood Design Principles
1. According to the structural characteristics of the building, set up an air shaft nearby, divide the exhaust and make-up air systems, and make the piping system "short, flat, smooth, and straight" to reduce system resistance and system noise;

1.Duct reinforcement
(1)Reinforcement measures should be taken in the following cases:
The diameter of the spiral duct is greater than or equal to 800mm, and the length of the pipe section is greater than 1250mm or the total surface area is greater than 4 square meters. Reinforcement measures should be taken.

Air return grilles: These air conditioning grills are much simpler since they do not have the need to direct the air to any place. The main function of this type of grille is protection so that nothing gets into the ventilation ducts, and for this reason they have horizontal slats for an aesthetic reason.

Advantages of circular air ducts
Advantage 1: High air tightness. As we all know, no matter whether it is conveying gas or relying on gas for material transportation, the gas conveying pipeline is the most forbidden to leak.

6.Duct painting:
Two coats of antirust paint (red lead antirust paint, iron red antirust paint, aluminum powder iron red phenolic antirust paint are acceptable) are applied on the inner surface of the thin steel air duct and the outer surface of the air duct that needs heat preservation. The non-insulated outer surface of the thin steel air duct is coated with an anti-rust primer and a second oil-based blending paint; the color of the paint should be coordinated with the painting and decoration

Ventilation grille is one of the most important elements of air circulation in our family. Its function is simple; They allow air to enter or leave the room and can be connected to the outside of the building.

Central air conditioning system
The cold and heat sources of this system are centralized in the refrigeration station and boiler room, and the air handling equipment is centralized to form an air conditioning box, which is set in the machine room.
