The tightness of the air duct is an important quality indicator for the construction of ventilation and air conditioning projects. The method of testing this quality item can use light leakage detection or air leakage test.

The composite air duct is made of a variety of mixed materials, including phenolic, glass magnesium and other air ducts. Composite air duct is a new generation of environmentally friendly and energy-saving air ducts that replace iron sheet air ducts and glass fiber air ducts. The composite air duct product is made of two layers of high-strength inorganic materials and one layer of thermal insulation material as the base material, and adopts adhesive technology and special structural combination

Stamping and forming equipment, degreasing cleaning equipment, spraying equipment.​​

A CNC machine is a computer controlled manufacturing machine. Purchasing a CNC machine for your pre-insulated duct fabrication is a good choice to speed up the projects.

1.1What is a refrigerant and how does it work?
A working substance that transfers heat between the object to be cooled and the ambient medium, and finally transfers the heat from the object to be cooled to the ambient medium for the refrigeration cycle.

Since ancient times, humanity has sought the shelter of caves to shelter from heat and cold. The fire was the first advance of humanity towards air conditioning, of course the concept has changed a lot, originally it was more of a necessity and today it is a comfort.

1. Basic principles
1.1 Strengthen regional and personnel management to avoid cross infection
During the epidemic, internal divisions should be clarified and management should be strengthened, especially the management of public areas such as halls, kitchens, restaurants, and toilets.

Not using things is as harmful as using them wrongly, the air conditioning equipment tends to be off for many months, especially in the winter months it can cause breakdowns, some devices only work one month a year,

1.1Classification by purpose of use
Comfortable air conditioner---Requires suitable temperature, comfortable environment, no strict requirements for the adjustment accuracy of temperature and humidity, used in housing, offices, theaters, shopping malls, gymnasiums, automobiles, ships, airplanes, etc.

Thanks for choosing a Ventech CNC duct cutting machine. Through previous communication, you’ve got some basic knowledge of our CNC duct cutting machine.

In the ventilation project, the air duct should be made of suitable material according to the project requirements. Design and construction personnel need to fully understand the air ducts of different material properties and their use, application occasions, and under what circumstances the air ducts need to be insulated, so as to build a reasonable and durable ventilation pipe network system.

When you hold the phenolic insulation board, you will find it is light and easy to transport. Phenolic insulation board is a closed-cell rigid foam plastic made by scientific formula with phenolic resin and flame retardant, smoke suppressant, curing agent, foaming agent, and other auxiliaries.
