Practical Guidance on Taking Accurate Duct Velocity Measurements LEVCentral Expert Commentary The Pitot Tube remains one of the most important instruments used by LEV engineers, commissioning engineers and occupational hygienists. When used correctly, it provides a reliable method of measuring …
Understanding How Captor Hoods Actually Work Captor hoods are one of the most commonly used forms of Local Exhaust Ventilation (LEV) hood found throughout industry. However, despite their widespread use, captor hoods are often misunderstood. Many LEV systems fail to …
Low Volume High Velocity (LVHV) extraction systems have become increasingly important in controlling dust generated by portable power tools and hand-held processes. By capturing contaminants directly at the point of generation, LVHV systems can significantly reduce worker exposure to hazardous …
When a Demonstration Overwhelms a Fume Cupboard The “Screaming Jelly Baby” experiment is one of the most well-known chemistry demonstrations performed in schools and colleges throughout the UK. The demonstration involves dropping a jelly baby into molten potassium chlorate, resulting …
Measuring the Real Control Effectiveness of Captor Hoods This OXYL8 training video explores one of the most frequently misunderstood aspects of captor hood performance: determining the effective control distance (or control zone) of a captor hood. Captor hoods are widely …
One of the most common faults discovered during LEV commissioning and Thorough Examination and Test (TExT) is a centrifugal fan that has been wired incorrectly and is rotating in the wrong direction. Surprisingly, when a centrifugal fan runs in reverse, …
