Abstract: Embodiments of the present invention provide a blower enclosure configured to secure to a base and house a blower. The blower enclosure includes a main body defining an internal blower chamber, and at least one access door configured to open to allow access to the blower. The enclosure may also include a gland plate secured over a preformed opening in the main body. The gland plate may include an O-ring configured to sealingly engage an outlet pipe of the blower. The enclosure may further include a fixed filter shroud configured to allow a user to install and remove a filter element without the use of a tool.

Abstract: A method and apparatus for applying a uniform electrostatic force to a web moving between a pair of electrodes to create an electron wind that urges the web toward one of the electrodes controls the current forming the electron wind to maintain the current and the wind force substantially constant even though impedance may vary. The method may be used to provide a hard nip, to adjust tension, to spread and/or to smooth a coating, to remove curl, and to cure a coating.
