Ducted vs. Ductless Lab Ventilation — What the Decision Really Involves

Laboratory ventilation design is fundamentally a risk management exercise. One of the most common decisions faced during laboratory planning is...
Laboratory ventilation design is fundamentally a risk management exercise. One of the most common decisions faced during laboratory planning is whether contaminated air should be ducted and exhausted from the building, or filtered and recirculated within the space. A recent whitepaper examines those tradeoffs from an engineering perspective, with an emphasis on how each approach performs over time. Two approaches to the same problem Ducted ventilation systems remove contaminated air from the laboratory and discharge it outside the building. Because...

Is Your Lab Exhaust System Doing More Work Than It Needs To?

Laboratory exhaust systems are among the major energy consumers in research buildings, and they run continuously. In facilities with a...
Laboratory exhaust systems are among the major energy consumers in research buildings, and they run continuously. In facilities with a single fume hood or low hood density, the architecture of that exhaust system is often carried over from designs built for much larger, centralized laboratories. A recent whitepaper evaluates whether that default assumption holds up when analyzed at the single-hood scale. What every lab exhaust system must do Laboratory fume hood exhaust systems have two jobs: keep contaminants contained at...

Unlocking Efficiency: How VFDs Optimize Fan Performance and Save Energy

In today’s energy-conscious world, optimizing the efficiency of industrial and commercial ventilation systems is more critical than ever. A common...
In today’s energy-conscious world, optimizing the efficiency of industrial and commercial ventilation systems is more critical than ever. A common challenge in system design is that fans are often selected based on a standard motor speed, which may not perfectly align with the system’s actual requirements. This mismatch can lead to oversized performance, wasted energy, and unnecessary operational costs. Fortunately, there is a powerful solution: using a Variable Frequency Drive (VFD) to precisely control the fan’s speed. In this article,...

Are Your Exhaust Fans Really Keeping You Safe?

Proper exhaust fan sizing represents only the initial step in effective ventilation design. This article examines the critical importance of exhaust plume height and the potential consequences of inadequate plume dispersion, including re-entrainment of hazardous fumes into building systems.

Most engineers and facility managers assume that if an exhaust fan is sized correctly, the problem is solved. But here’s the hard truth: if your exhaust plume doesn’t rise high enough above the roofline, you could be sending hazardous, corrosive, or odorous fumes right back into your building. That means: Risk of re-entrainment into air intakes Accelerated corrosion of building structure Potential code compliance issues with local authorities Increased liability for both designers and owners The question is simple: how...

The V-Series Lab Exhaust Fan - A New Way to Exhaust Fumes from Labs

In laboratory design across North America, it's common to see large, metal-clad exhaust systems with dilution nozzles towering over rooftops....
In laboratory design across North America, it's common to see large, metal-clad exhaust systems with dilution nozzles towering over rooftops. These systems aim to minimize re-entrainment by diluting hazardous fumes with ambient air. While the intention is sound, the assumption that dilution is the only compliant strategy is increasingly outdated. Enter the V-Series — a high-performance, corrosion-resistant lab exhaust solution developed by PLASTEC Ventilation. 100% Corrosion Resistance with Polypropylene The V-Series is made entirely from polypropylene (PP), offering unmatched resistance to...

In industrial, chemical, and hazardous environments, ventilation systems are vital for maintaining safety and regulatory compliance. The design and operation of these systems must follow the standards for explosion protection ventilation systems, which include globally recognized frameworks like the IEC 60079 series, the ATEX Directives in Europe, and NFPA standards such as NFPA 68 and NFPA 69. These standards define how to classify hazardous zones, select suitable equipment, and apply explosion protection methods. They cover flameproof enclosures, intrinsic safety, venting,...
