PLASTEC Ventilation introduces its new fan curves

When it comes to choosing a fan for your buildings, laboratories, fume hoods, cabinets or scrubbers, you will need to understand fan curves sooner or later.

What's new about PLASTEC fan curves ?

New design

Reminder: Each fan is defined by a non linear curve of the Static Pressure Ps in function of the Flow Rate Q at a given speed rotation N. 

  • On PLASTEC graphs, by convention the red curve represents one fan model at a given power and speed. This is the fan performance without frequency variation, i.e. at maximum speed (60Hz)
  • The blue doted curve represents the same fan performance but at lower speed rotation.

Fan curves explanation

Energy saving alternative models

If you take a look at a few models like the PLASTEC 25 or 35, you may notice that some curves are split in two parts. The idea here is to offer two different powers on the same curve: 

  • A smaller power for lower CFM. This model is called "ES" for Energy savings
  • A higher power for higher CFM. This model is called "MP" for Maximum power

This new system allows our customers to find the best fit for their fan installations while saving energy at a lower price. 

New data tested and approved by AMCA International These brand new curves are approved by AMCA International since the beginning 2021. All PLASTEC Ventilation fans have been tested according to AMCA 211 and 311 for Sound and Air at the AMCA partner laboratory "CETIAT".

Plastec Ventilation Inc has extensive experience in the field of fume extraction systems. We offer a comprehensive line of high-quality chemical, corrosion, and even carbon-impregnated explosion resistant polypropylene fans and blowers dedicated to the needs of the industry.

Our products are built to last and highly cost-effective, which makes them the perfect solution for many applications that require fume

exhaust extraction. Some examples include ventilation of acid or chemically-based manufacturing processes, laboratories, water or wastewater treatment, hospitals, medical facilities, educational institutions, chemical production, fume hoods, natatoriums, vehicle exhaust, and much more.

Our plastic polypropylene (and Stainless Steel) fans are typically installed in highly aggressive environments where even metal, FRP fans

(with epoxy coatings), and others will fail.

In 2007, we added Electro Polished 316 Stainless Steel blowers to our product line, as well as Laboratory Hood Air Flow Controls and Monitors with a series of Inverter/VFD Drives. We also offer a Carbon Fiber Impregnated Polypropylene Housing for explosive atmosphere applications.
