VENTILATION
PE-FLEX
The basic element of the PE-FLEX® ventilation system is PE-FLEX® ventilation ducts made of first-grade PE-HD plastic. PE-FLEX® double-layer ventilation pipe is designed to distribute fresh and exhaust air in the house and is used to connect plenum boxes to distribution boxes.
For added protection, the smooth inner layer has bactericidal, fungicidal and anti-static additives. PE-FLEX cables come in two variants: Standard and Spectra 1000.
Available in three diameters: Ø50, Ø75 or Ø90 mm

PE-FLEX STANDARD
PE-FLEX SPECTRA 1000
- Almost 100% level of antibacterial and antifungal protection
- innovative Spectra 1000 additive inhibiting the growth of microorganisms
- The double-layer construction of the cables provides high compressive strength
- made of odourless and halogen-free raw materials
- available in 3 sizes Ø50, Ø75 or Ø90 mm
- high flexibility of wires allows free shaping, bending and routing of cables
- antistatic properties of the cables reduce the settlement and accumulation of dust in the pipes
- resistant to installation in the insulation layer of the ceiling and in the ceiling itself and poured in concrete
- no shape memory allows for aesthetically pleasing straight sections with fewer fixings
Properties
Bactericidal and fungicidal
More than 99% microbiological protection!
Mechanical ventilation is responsible for the continuous inflow of fresh outside air into the house and the removal of stale air, thus ensuring safe and healthy living conditions for all household members.
But how to make the ventilation system provide the highest standards of operation for many years of its life?
The solution is to use PE-FLEX ventilation ducts with the innovative Spectra 1000 coating, which has laboratory-confirmed bactericidal and fungicidal properties that guarantee no microbial growth in ventilation systems for many years.
Reduction of bacteria in PE-FLEX Spectra 1000 pipes
Bacteria reduction rate after 24 hours of contact with the inner layer of the pipe

Bactericidal coating
internal
30 year warranty
Phosphorescent under UV light, the inner wall of PE-FLEX pipes is made entirely of antibacterial and antifungal material, which protects it from the development of microorganisms on its surface. Additions of silver, copper and other microbial active compounds practically ensure the indefinite performance of the Spectra 1000 coating, which comes with a 30-year guarantee of effectiveness. Spectra 1000 is considered the best germicidal air duct additive on the market!
PE-FLEX Spectra 1000
vs. Standard
PE-FLEX ventilation ducts come in two variants that differ only in the properties of the inner coating:
– green Standard wires have bacteriostatic and fungistatic additives to provide basic microbiological protection.
– Spectra 1000 gray pipes with a coating that provides very high bactericidal properties and is the only one on the market with tested fungicidal properties of up to 100%.
Anti-static additives
smooth interior coating
Extensive experience in the industry has allowed us to create a pipe that combines an ideal compromise between the smoothness of the inner layer that maintains low airflow resistance and lack of dirt deposition, and the almost imperceptible notches that dampen air noise and ensure high flexibility of ventilation ducts.
To keep the entire ventilation system in the house as hygienic as possible, the inner layer has anti-static additives that reduce the settlement and accumulation of dust in the pipes.
High durability
Over 800N of compressive strength!
PE-FLE ventilation ducts even have more than twice the circumferential strength of other pipes on the market!
High durability ensures the safe installation of the system, without worrying about possible damage to it during the finishing of the building and for many years of use. It also allows the installation of ducts in the floors and ceilings of buildings and direct concrete pouring.
High flexibility
and no shape memory
Anyone who has installed a recuperation system at least once realizes how important the flexibility of the ductwork is to the comfort of its installation. The appropriate composition of plastics, the proportions of the pipe wall thickness and the appropriate width of the humps make it possible to make sharp bends of PE-FLEX pipes if necessary .
A very important feature of PE FLEX pipe is also the lack of shape memory, which makes it easier to run long and straight sections immediately after unrolling the pipe from the roll.
Self-extinguishing properties
Security for you and your home
To ensure peace of mind for residents of a house equipped with PE-FLEX recuperative ventilation system, all PE-HD plastic ventilation ducts have self-extinguishing properties.
In addition, for your family’s complete safety, Spectra’s gray PE-FLEX pipe is made of 100% halogen-free materials !
Hygienic certificate of PZH
Trust only proven products
PE-FLEX ventilation ducts are hygienically certified by the National Institute of Hygiene, which confirms the safety of their use in domestic ventilation systems.
Easy cutting
"made to measure"
with a dedicated PE-FLEX cutter
PE-FLEX is not only a ventilation system, but also a tool to facilitate the work of the installer. With the help of the PE-FLEX cutter, specially designed for corrugated pipes with diameters of 50, 75 and 90 mm, cutting flexible pipes is easier, faster and, most importantly, more accurate.
Quick and easy installation
special holder for PE-FLEX pipes
With a dedicated PE-FLEX holder for ventilation ducts, making installations is even easier and faster. The special design of the bracket makes it possible for even one person to mount pipes from the ceiling , and the lockable clip ensures that the pipe will not dislodge on its own. The ability to join brackets together also allows several pipes to be installed side by side using fewer studs or screws.
Three types of diameters
depending on the installation method
Ø50 pipe
Usually used in the insulation layer of the ceiling, when the ventilation system was not planned in advance and the standard thickness of the polystyrene foam layer in the floor was not increased.
Ø75 pipe
Remember! Increase the thickness of Styrofoam in the floor to a minimum of 8, and preferably 10 cm!
The most common diameter of ventilation ducts used in Poland. It is suitable both for installation in the insulation layer of the ceiling and for installation in suspended ceilings.
Ø90 pipe
The larger diameter of the pipe allows to transport more air over a greater distance. It is used most often in large and spreading ventilation systems.

Selection of the number of ducts depending on the amount of transmitted air
The amount of air transferred, and thus its velocity, is crucial in terms of the air resistance generated by the installation, as well as possible noise. Therefore, when designing a ventilation system, the number of strands of individual ventilation pipes should be adequately predicted, so that at maximum air flows the velocity in the pipes does not exceed 3 m/s.

Installation of ventilation ducts
PE-FLEX in the ceiling insulation layer
- Boxes and ventilation pipes are mounted directly on the ceiling.
- The installation is hidden in the insulation layer of the ceiling, for example, in Styrofoam, which should be at least the same thickness as the diameter of the pipe.
- A good solution is to lay a thicker layer of ceiling insulation and cover the entire ventilation system
- Underfloor heating can be installed directly over PE-FLEX® pipes - the two installations do not interfere with each other.
- When installing an expansion box, a hole should be made in the ceiling. From below, only the anemostat is visible, and the entire installation is covered with concrete screed and floor
