Everything You Should Know About HVAC Ductwork Fabrication!

Duct Board is a fiberglass product with an aluminum foil surface exposed to the airstream. Duct board is an alternative to galvanized steel in the fabrication of rectangular duct.  Used most in specific regions and on specific types of jobs including apartments, condos, and residential new construction, specifically tract homes.

VENTECH manufactures various types of Duct Board Cutting Machines for pre-insulated duct fabrication, including cnc cutting machine, bending machine, duct board grooving machine, square duct electronic cutting machine, etc.

As an industry-leading provider of the most complete, innovative machinery and equipment for HVAC ductwork fabrication, VENTECH also offers solutions to improve insulation cutting processes that eliminate the duct liner bottleneck impacting your operation’s bottom line. 

Use of conventional and machining methods of cutting insulation requires part replacements and compromises the integrity of the insulation. 

VENTECH’s cutting systems can bring accuracy and efficiency to the cutting and fabrication of fiberglass and elastomeric foam insulation to keep your operation running proficiently and safely. 

VENCETH HVAC Laser Cutting Advantages:

1. Laser cutting is a non-contact process that eliminates the need for expensive tooling and retooling costs.

2. System costs and monthly operating expenses are significantly lower than those of similarly operating equipment made by leading foreign and domestic manufacturers.

3. The high positioning accuracy provided by the ultra-reliable servo system and the thin cutting beam allow the operator to successfully make precise cuts in the finest materials without damage during the cutting process.

4. High quality exhaust system and the safety guarantee of eliminating exhaust gas emissions and compliance with environmental standards allow for considerable electrical and thermal energy savings during forced ventilation.

5. No complex mirror system requiring constant adjustment and expensive maintenance.

HVAC grilles and diffusers are the exit ventilation points for heating, ventilation and air conditioning (HVAC) systems. Although they are occasionally used as return vents, their primary purpose is to introduce conditioned air into the space so that it is evenly distributed and mixed with minimal noise. 

HVAC grilles and diffusers come in a variety of standard sizes, usually square, rectangular or round; they usually have a set of louvers or fins that direct airflow in a pre-set pattern. Larger industrial grilles and diffuser may include adjustable louvers or dampers that can be adjusted manually or automatically to control airflow.

Although diffusers are often seen as decorative grilles for inlet vents, they play a vital role in the effectiveness of HVAC systems and should be properly matched to any given application.
