Low-noise pipes

The low-noise pipe is a one-touch product that enables convenient and
fast construction this product reduces noise more than twice as much as before.
And NC2 is clamped and NC1 is cap-tightened it's different.

NC2
feature

PRODUCT FEATURE

By applying innovative sound insulation technology, it is effective in reducing living noise and improving the convenience of the people.

Excellent flame retardancy
Excellent noise effect and flame retardancy using special PVC material
A smooth flow
Smooth surface compared to conventional triple NC pipes for smooth flow rate
Excellent shock resistance
Better impact resistance than normal PVC pipes
Excellent insulation effect
Special material for thermal insulation and insulation is better than normal PVC pipes
Maintaining the quality level
Maintaining an even quality level with a simple manufacturing process compared to the existing triple NC pipe

NC2 toilet bowl elbow
feature

PRODUCT FEATURE

The NC2 toilet bowl elbow adopts its own patented elastic variable nozzle (EVN) technology to minimize the drainage noise and control the flow of fluid.

3^rd generation
elastic variable nozzle

An innovative technology that controls the behavior of the drainage fluid by placing an elastic soft nozzle that varies depending on the flow rate in the elbow of the toilet to suppress noise and limit the external transmission of the generated noise

Noise-reducing products (5db reduction compared to NC) *Measurement criteria (toilet test results)

Sensory noise reduction more than twice as compared to NC products

Test performance

Discharge performance of toilet bowl according to the test method. Selection of test specimens and discharge performance test by analyzing major causes of pipe clogging at home and abroad

· Test specimen for toilet discharge performance test

· Add sample of main cause of pipe blockage. Sanitary pads, wet wipes, floss

NC1 toilet bowl elbow
feature

PRODUCT FEATURE

A NC1 toilet elbow designed to minimize wastewater noise is an eco product that solves various problems such as noise, heat insulation, which are disadvantages of existing products.

Low-noise
Effectively block external transmission in case of drainage noise
Shock relief
Use a soft PVC at the point where the major impact sounds occur to minimize the drain impact sounds
NC toilet elbow feature
A layer of air is formed inside the product to prevent condensation on the surface of the pipe due to high thermal perfusion resistance
