  • Air Velocity Temperature Measurment All-in-One (.pdf)
    If you are involved in HVAC installation or maintenance, or if you work with air flow in an industrial process, lab, or. research facility, then you will want to know about the new FMA1000 Air Velocity/Temperature Transmitter-Indicator. from Omega Engineering. This compact, full-featured unit
  • Air Showers- Increasing Productivity and Reducing Operating
    . velocities of 7,800 feet per minute (fpm) and circulate. mechanical bond with particles, making them difficult. 1,900 cubic feet per minute (cfm) of air. Velocity is. measured at the nozzle, and the cleaning effectiveness. deteriorates as the workers' distance from the nozzle. increases. Therefore
  • Hybrid Refrigerated/Desiccant Compressed Air Dryers
    of several minutes rather than seconds as with heatless desiccant dryers. This eliminates high air velocities in the desiccant beds that cause desiccant to breakdown. And it occurs far less frequently than heated or heatless dryers. Combining smaller desiccant beds with less frequent service intervals
  • Air Curtains Circulate Good Ideas for Food Service Facilities
    to first understand how air curtains work. How Air Curtains Work. Air curtains consist of a powerful fan that creates an invisible barrier of high velocity air to separate different environments. Typically mounted over doorways, this fan pulls in conditioned air, accelerates it and forces it through
  • Without AMCA Certification, Air Curtain Specification Is No Sure Thing
    rate listing of 1,200-cfms but operate with a power rating of 1.2 and 1.6-kW respectively, demonstrate an energy usage difference. For velocity projection and uniformity, the air curtain is placed on its side on the floor. Peak velocities are measured with an anemometer across the width of its air
  • How to Get Cleaner Air: Your Bottom Line for Dust Collection
    . What The Experts Say. According to EPA sponsored research, downward. uneven air velocity distribution and significant areas. flow of the dirty air stream in a dust collector results. of high velocities in the collector, prompting greater. in superior filtration performance. The American. potential

    is compared to the. of air velocity around the occupant [3] are important. temperatures measured at various locations in the. Other variables that influence thermal comfort are the. vehicle by conventional thermocouples. solar load, the occupant's clothing, and the humidity in. the passenger compartment
  • Understanding Forced Air Cooling in Power Supplies (.pdf)
    . supply requires convection cooling, then it's usually just a matter. of making sure that there is sufficient space around the power. Therefore the air velocity required is: supply and that the ambient temperature isn't exceeded. Power. supplies that include a fan require careful installation
