Engineering Library
Engineering documentation, calculators and product files - built for HVAC engineers, system integrators and installers.
Learn what CE, UL, ETL and RoHS mean for ventilation fans, and understand which certifications may be required for different export markets.
Compare inline duct fans vs exhaust fans. Learn the differences in installation, airflow, static pressure, and applications to choose the right ventilation fan.
If you are dealing with long duct runs, multiple rooms, or spaces where a traditional surface-mounted fan is impractical, an inline fan is often the only solution that delivers consistent, powerful airflow.
Step-by-step CFM sizing using NFPA 96 hood capture velocity and equipment heat load. Includes a worked example for a 12 ft canopy hood over a 6-burner range.
Three-year TCO model comparing EC and AC fans across a 2,000 m² hydroponics facility. Payback typically lands inside 18 months at $0.12/kWh.
Vibration isolators, service-loop slack, ducting alignment and access-panel placement for inline fans in <300 mm plenums.
Lubrication intervals, bearing temperature thresholds, dynamic balancing and impeller wear inspection — packaged as a printable annual checklist.
How to estimate friction loss and dynamic loss across runs >30 m without specialist software, using simplified Darcy-Weisbach with K-factors.
Temperature-based PWM control and ambient cut-out logic typically save 35–50% of cooling-fan energy on outdoor 60–180 kW chargers.
