2019-12-10Modular ductwork TRANS-Quick system for dust extraction

Industrial dust extraction is used in welding industry, metalworking industry, woodworking industry, food and pharmaceutical industry. Installation air-tightness is crucial for this type of systems, since any kind of leakage may cause dust leaking outside of the ductwork and reduce dust extraction efficiency.

2019-11-18Is Elastomeric Closed-Cell Insulation a Good Solution for Ventilation?

Why insulate the ductwork? Insulation protects against condensation and energy loss as well as attenuates noises. Find out more about the pros and cons of elastomeric foam insulation in comparison to glass and stone wool.

2019-07-22Iris dampers for Circular Ductwork - accurate and quick airflow control

Quick, silent and efficient – these are the distinctive features of the GBL iris dampers used to adjust and measure airflow. GBL iris dampers allow for quick and exact adjustment of the airflow. They work very well wherever accurate airflow adjustment and individual control over the comfort conditions and parameters are required.

2019-07-08Air Volume Regulators CAV & VAV- overview

Airflow regulators maintain desired air flow rate in particular branches of ducting system regardless pressure variation inside the ducts. It makes the process of system design much easier but noise generation and operating costs should be considered that is why low initial pressure set up is crucial. Air flow regulation can take place both in supply and extract air duct

2018-01-10Ductwork cleanliness standards with M1 classification

It is hard to overestimate the cleanliness . Especially nowadays, when alarms go off about air full of pollution like particle matter, hydrocarbons or Carbon and Sulphur oxides.

2017-06-27Vibration damping solutions in ventilation systems

In a standard ventilation system, there are many vibrations and noises which are transmitted in the metal ducts, generated by air handling units - fans, heat recovery units, and chillers. A properly installed ventilation ductwork should have built-in components to counteract the transmission of these vibrations or significantly isolate and dampen them.
