HVAC DUCTING

Ducts are used in Heating, Ventilation & Air Conditioning (HVAC) to deliver the supply air and transit the return air and remove the exhaust air.  As such, air ducts form a medium through which a conditioned air is transferred to an ambient space therein achieving acceptable indoor air quality and ensuring suitable thermal comfort. Ducts are fabricated DW144/SMACNA Standards and fully equipped with the updated specifications and client requirement.

MILD STEEL

Fabricated from high-quality Mild Steel and invariably coated in Red Oxide paint MS ducts are largely used in kitchen exhaust applications owing to its inherently fire resistant characteristic which can be further enhanced by externally applying a fire-rated fabric bonded both physically and mechanically into the ductwork. MS Duct is normally fabricated from 1 mm up to 3 mm thickness. MS Angles are fitted at all Transverse Joints. Self-flange construction is available as an option.

STAINLESS STEEL

These are useful for businesses and large manufacturing companies which calls for its specialized use in voluminous and industrialized applications. Use of stainless steel ductwork for any specialist application is recommended for its superior strength and rigidity. Its appearance though is much sleeker than the one in an aluminum duct it stands way out for its corrosion resistant characteristic. For SS Ducts stainless steel sheets are available in two qualities i.e. Grade 316 & Grade 304.

SPIRAL DUCTING

These ducts are made out of high quality GI sheets manufactured by metal industry’s leading steel manufacturers and use of high quality GI sheets ensures rigidity. Spiral duct is attractive and is frequently specified by architects because of its superior aesthetic appeal; it can be finished to blend in with or stand out in an indoor ambience.

RECTANGULAR

It is manufactured to meet the most stringent HVAC/Industrial specifications and quality standards. Rectangular GI Ducts are fabricated out of hot dipped galvanized steel sheet of lock forming quality as standard duct material. As per DW144/SMACNA Standards and fully equipped with the updated specifications and client requirement.

ALUMINIUM

This lightweight malleable and corrosion resistant metal in Plain type (Matt finish/Reflector) air duct is widely used in areas such as swimming pool, clean rooms for sensitive industrial applications etc. Stucco embossed type which is relatively dent and scratch resistant is largely used as cladding on exposed Rectangular or Spiral GI ductworks.

FIRE RATED DUCT WORKS

Firemac FM Ductwork Systems uses a flexible glass fibre fabric, bonded both physically and mechanically onto the duct to give the required fire rating. The fabric material is only 0.4 mm thick and adds virtually nothing to the overall weight of the duct. The fabric is silver grey in appearance, unobtrusive and gives a neat, aesthetically pleasing finish. During the finishing process, the fabric is overprinted with FIREMAC Logo and FIRE RATED Legend to ensure it remains independent of standard ventilation ductwork and service trays. Ductwork is made in the normal manner, broadly following the requirements of DW144 / SMACNA, and there is usually no requirement to upgrade the gauge of steel used to achieve the required fire resistance. Once the duct has been fabricated the fabric is applied quickly and easily and bonded to the duct using a contact adhesive.
