The main function of ventilation and air conditioning is to provide the oxygen needed for human breathing, dilute indoor pollutants or odors, remove pollutants generated by indoor processes, remove indoor waste heat or humidity, and provide air needed for indoor combustion. It is mainly used in households, commercial, hotel, school and other buildings.

Phenolic foam plastic is a new type of flame retardant, fireproof and low smoke insulation material. It is a closed-cell rigid foam made of phenolic resin with flame retardant, smoke suppressant, foaming agent, curing agent and other additives.

4.Implement quality inspection standards and acceptance specifications In order to ensure that the project reaches an excellent level, the quality inspection during construction should be in accordance with the "Code for Construction and Acceptance of Ventilation and Air Conditioning Engineering" (GB50243-2002) and professional construction atlas and the requirements of the construction party conduct.

1. The internal sundries were not removed before the air duct was installed
The internal and external sundries should be removed before the air duct is installed, and the cleaning and finished products should be done well. After construction, the pipe opening should be blocked in time.

The handling and loading and unloading of the air duct should be handled with care to prevent damage to the finished product. For the construction in the air duct, clean work clothes, work gloves, and work caps must be available.

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.
