Modular Dust Extraction Ducting

2019-12-10Modular Dust Extraction Ducting

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.

Air Volume Regulators CAV & VAV- overview

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

MOCarz-CA - Upgraded air filtration with activated carbon

2019-02-20MOCarz-CA - Upgraded air filtration with activated carbon

Referred to also as activated charcoal or activated carbon is a substance in the form of dust consisting of elemental carbon, and finely crystalline graphite. The most important feature of actrivated carbon is a vast surface of adsorption. Adsorption is the process by which liquid or gaseous molecules are concentrated on a solid surface, in this case activated carbon (activated charcoal).
