Ducting is used to connect inline fans with items like spigot flanges, Air Carbon scrubbers or other fittings . This flexible aluminium Ducting is specifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems.
Rectangular ductwork is simply ducting that is squared or rectangular edges. It is not normally as common as spiral ducting because it’s not as efficient but it does have its uses. It is typically called into use where height restrictions or tight spaces won’t suit round ducting.
Round ductwork creates less airflow resistance. This means that air flows smoothly through the ducts, resulting in more efficient air conditioning. Several methods can be used to measure airflow in ducts.
A fiberboard air duct is mostly preferred for heating and cooling systems because it is insulated. But just like the Fiberglass lined air ducts, these air ducts are not recommended for ventilation as they too can become a home to mold and bacteria
Ducts are commonly joined together by two means – the simple, anchoring Drive Cleat and the reinforcing connector. They are also used in combination, where desirable.
Spiral ducting is used to transport large volumes of air from one point to another. It is a common choice of ducting product for ventilation systems. You might not need a spiral wound ducting ventilation system in your home, but commercial use is on a different level.
What does HVAC mean? HVAC is an acronym that stands for Heating, Ventilation, and Air Conditioning. The term HVAC is used to describe a complete home comfort system that can be used to heat and cool your home, as well as provide improved indoor air quality.
A plenum is a box or chamber that connects the air handling unit (AHU) to the ductwork in an HVAC system. It distributes conditioned air throughout the building and provides a return path for unconditioned air back to the AHU.
The supply plenum is an air distribution box. It’s attached directly to the supply outlet of the HVAC equipment–that is, the outlet that releases chilled or heated air into your home. The air ducts that distribute the air into the individual rooms of your living space all connect to this plenum.
The return plenum box receives used air from the return vents and distributes it to your HVAC unit to be heated or cooled again. The used air must pass through a filter before entering the return plenum, ensuring that it’s clean before it reenters your AC, heat pump, or furnace.
Galvanization is the process of applying a protective zinc coating to steel or iron in order to prevent premature rust and corrosion. Proponents of galvanized steel, who may use it to construct or repair steel structures, for example, benefit from lower maintenance and repair costs because of its special properties.

Stainless steel sheet metal is employed in building cladding to create sleek and modern exterior facades. Its corrosion resistance and aesthetic appeal make it suitable for enhancing the architectural appearance of commercial and residential structures.
Extraction canopies are one of the key pieces of apparatus when it comes to tackling kitchen ventilation. The prime function of a kitchen canopy is to protect the area surrounding the kitchen appliances from soiled matter heat and flame.
A pipework bend that is formed by cutting the pipe into angled segments, which are then joined together to form the bend.
Square to rounds are usually laser cut and folded in multiple segments. The one shown above was a simple mild steel design so it could be made in two laser cut halves. They are folded using “segmented bending” which is where multiple folds are used to create a radius.
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.
Balancing dampers are control dampers that balance the flow of air in an HVAC system. The intended applications for these dampers do not include a positive shutoff or for automatic control. The MBD series are shipped manual hand quadrants that can lock in place.
A roll shaped galvanized steel angle incorporating a long term non hardening sealant , which guarantees a reliable air tight connection – reduces the requirement for post installation sealing of the duct.
A roll formed galvanized steel angle incorporating a long term non hardening sealant , which ensures a trusted air tight connection – reduces the need for post installation sealing of the duct.
Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel material from the cut. During the process, an electric arc is struck between an electrode (cathode) and the workpiece (anode).
Dropper System. The Weather Guard dropper sits on the roof and connects the evaporative unit to the ducting system. 2. Ducting. Ducting distributes the cool, freshly conditioned air to each room in the home.
A roof vent cowl discharges air in a vertical position. Used in applications where a duct termination is required at roof level. Fitted with mesh to stop wildlife entering into the duct termination point.
