Engineering solution
What this equipment is designed to solve
GTK tubular silencers are used in round ventilation ducts to reduce aerodynamic noise. Inside there is a perforated channel and a sound-absorbing layer; length, diameter and design are selected according to the network cross-section, air flow and the required acoustic result.
The current site set does not have a separate passport for the GTK series, so the noise reduction range, permissible temperature and humidity are not published as confirmed parameters. Request calculations and drawings of the selected design.
Application
Suitable applications
- Reducing noise in supply ventilation systems
- Reducing noise in exhaust systems
- Soundproofing of ventilation units
- Ensuring acoustic comfort in rooms

Frequently Asked Questions
Long (L=980 mm) – reduction by 25–35 dB. Short (L=480 mm) – 15–20 dB. To calculate the exact value, you need the frequency spectrum of the fan.
Mineral wool in a perforated galvanized steel casing. Flammability class – NG (non-flammable). Service life – 15+ years.
L=480 mm – for typical tasks (offices, shops). L=980 mm – for facilities with strict requirements (hospitals, laboratories, residential buildings). If in doubt, we recommend the long model.
