EPP DUCTING

EPP DUCTING

90˚ ventilation bend made of expanded polypropylene (EPP).

Dehum PTY LTD supplies all ducting and ducting accessories for your next project.

Bends are produced in diameters 125, 150, 160 and 180mm.
The standard wall thickness is 15mm (grey). Available on request 43mm thick (black colour). Each bend is delivered with one female coupling in the set, the connection method eliminates thermal bridges. The 90 ̊ bend can be cut in half along the extrusion, forming two 45 ̊ bends (an additional EPP-MSF may be needed).

Lack of insulation on ventilation ducts is one of the most common assembly errors, which can lower heat recovery ventilation efficiency.
This kind of “oversight” will end up being very costly for customers, regardless of whether it was due to inexperience, insufficient knowledge, or a desire to save money or time.
The outdoor air and exhaust ducts, as well as all ventilation ducts after the heat recovery unit that pass through unheated rooms, should be insulated. A poor insulation method or quality of the insulation layer will result in condensation forming on the outside or inside of the duct.
It is also possible that cold air will be blown in due to uninsulated ducting.
An alternative to self-insulating ventilation ducts is the use of pre-insulated ducts. Insulated ducts are an excellent solution if quick installation is desired or if site insulation is not possible. We offer two insulated duct systems for mechanical ventilation systems with heat recovery:

Pre-insulated ducts and fittings with rubber insulation – steel ventilation ducts and fittings (bends, tees, male and female couplings, reducers) equipped with a rubber seals. Insulation is available in 4 thicknesses: 9, 13, 19 and 25 mm.

EPP Thermal ducting – made of expanded polypropylene (EPP), a material that provides excellent thermal insulation. Because EPP is already an insulator (as a material itself), it requires no additional insulation, which reduces assembly time. Two thicknesses are available: 15 and 43 mm.

EPP ducting is an alternative to insulated steel ducts or insulating ventilation ducts with one’s own hands using mineral wool or rubber foam. Ducts and fittings made of EPP (expanded polypropylene) are a ready solution for heat recovery installation.
Dedicated for installation in the outdoor and exhaust ductwork section.

Although expanded polypropylene “looks like” ordinary polystyrene, it is a stronger material, meaning that EPP is both lightweight and durable, and has excellent thermal insulation properties, which means EPP pipes do not need to be insulated.
Why is it worth buying EPP thermal ducting?

  • Quick installation (we do not need any additional mounting accessories such as screws, tapes, etc.)
  • Simple assembly – no special skills are required to connect EPP elements (pipes and fittings are push-fit connected); ducts can be cut according to our needs with a knife or saw
  • A limited number of system components – only 3-4 pieces
  • Light and durable design

EPP ducts come in two thicknesses: 15mm and 43mm.

A healthy life is inextricably linked to what we breathe. Air is the first and most important nourishment for all life forms. On average, a person breathes more than 12,000 litres of air per day.
