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

2018-06-19FAQ - Plastic Ductwork for aggressive environments

How to join plastic ductwork? What kind of welding device to use? What materials and diameters we have in stock? Can plastic ducts & fittings be stored outside? These and more questions about chemically resistant plastic ventilation ductwork.

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.

2017-08-04Modular TRANS-Quick system for dust extraction installations

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.

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.

2017-06-01Plastics in ventilation

Plastics based on polymers are applicable in many industry fields. The sanitary industry has taken advantage of the solutions based on the so called plastics for many years.

2016-06-27Brief - STRUT support system

Easy, quick and precise installation of ducts even in hard to reach places is the main advantage of the STRUT support system. The available selection of mounting accessories make for a fully professional fixing system.

2016-06-27PWQ-R flange cleat – for fast duct joining in hard to reach spots

The PWQ-R flange cleat is used for joining rectangular ducts. A channel of particular length is slid on PQ-20 or PQ-30 duct frame profiles. Bent edges provide an easy way to slide and hammer the channel. SAVE time and room!

2016-04-06What is ErP 2015?

ErP, that is, ”Energy related Products” means products related to energy. In order to accomplish the objectives of the EU Climate and Energy Package the EuP directive - “Energy-Using Products” was issued in 2005, which was thereafter replaced by the ErP directive in 2009.

2016-02-01Axial and in-line fans

Fans can be divided in several ways: by place of installation, e.g.: in line, wall mounted, ceiling mounted; by application, e.g. for kitchen canopies, chemical resistant, desmoking; by fan construction, e.g.: axial, radial. The present article will present the most important features of in-line duct fans as well as axial, wall mounted fans.
