AMCA Publication 2and AMCA Publication.
Halifax Fan have designed Plenum fans for optimum performance and reliability.
Cincinnati Fan manufactures twelve sizes of Model PL Plenum Fans , an excellent choice for efficient delivery of high air volumes in contained air handling systems.
Direct drive, backward curved plenum fans are the optimum choice for practically all commercial HVAC applications. The following information will show the many reasons why. First, the basics of fans, fan curves and fan laws will be introduced.
Next, fan selection will be covere including points of operation, fan widths . Plenum and Double Width Fans are designed for applications in commercial air- handling systems and pressurized plenums. The MPQN Plenum Fan is used in field-fabricated and factory-built air handling units to pressurize the entire surrounding air plenum. This allows discharge ductwork to be directly connected to the air handler from any direction.
The plenum fan design also saves space by eliminating the fan housing, transitions and diffusers . Application EPFN Plenum Fans are used in field-fabricated and factory-built air handling units to pressurize the entire surrounding air plenum. This allows the discharge ductwork to be directly connected to the air handler from any direction.
EPLQN Plenum Fans are used in field-fabricated and factory-built air handling units to pressurize the entire surrounding air plenum.
